for anyone who can not "preview xima form" : you can change the text size, right ? I mean 100%, 150% .... and so on .... right at that row, look on the right corner, there is a (really) small double arrow button >> name "Expand Pane" . Use that button instead of finding it on "View" tab, it seem that on new version of visual studio/xamarin, they change a little bit of the design so we can only use the double arrow button to preview the xamarin form.
I dont understand why all are writing XML Code ? So for what is the fucking Toolbox+Designer ? And why i cant place a Button in the middle of the form... Xamarin sucks.
This is a great tutorial but the latest release of Visual studio is pretty poor so far. The event handlers don't auto complete when creating them in XAML, errors are still underlined even after the error is fixed have to rebuild close/open file for the error to go away. Also PCL has been removed when creating a new Xamarin App, now you need to select .Net Standard.
Intellisense is broken in new VS install an older version if you can developercommunity.visualstudio.com/content/problem/167039/intellisense-completely-broken.html
it was jan.1,2018 when ive experienced a lot of bugs from xamarin, i posted the problem on SO but they said it was really a bug in Xamarin what a sad new year for me :'(
Hi Eduardo! I was able to follow your tutorial and everything worked perfectly. For the first time things started clicking, thanks to the way you teach. Miguel de Icaza would be proud of you. :) I'm heading to your udemy page for the complete Xamarin course. All the best! Thank you!
For the windows version UWP i.e. why i came here string fileName = "books_db.sqlite"; string fileLocation = Windows.Storage.ApplicationData.Current.LocalFolder.Path; string full_path = Path.Combine(fileLocation, fileName); LoadApplication(new MyBooks.App(full_path));
hey nice tutorial. I can't add book to table I'm getting an exception. SQLite.SQLiteException: Could not open database file: /data/user/0/com.companyname.App1/files/../Library/books_db.sqlite (CannotOpen)
Just in case anyone ran into an issue while trying to create a new Content Page as shown in the tutorial, the (partial) solution can be found here: developercommunity.visualstudio.com/content/problem/184365/cannot-create-new-contentpage-on-xamarinforms-proj.html I mean partial because even though you add the names of the files to this xml, it will not automatically generate them for you, so you will have to do it manually by creating a text file and "Save As" -> "All files..." -> add your extensions (.xaml and .xaml.cs) Cheers!
I was unable to display the Books in the homepage, it doesn't show any error or warnings, but simply doesn't display. I have followed the code thoroughly .
I followed your tutorial and by the way its very well done and easy to follow, great work, Unfortunately I can not open the database and get exception errors once I click on the Save button/ any help would be appreciated? Unhandled Exception: System.TypeInitializationException: The type initializer for 'SQLite.SQLiteConnection' threw an exception. occurred this was the error and halted it all.
I gave up, I cannot make Xamarin forms even run my app. I don't know if my computer is too slow. It seems like my HAXM is running and the emulators do run but they do not run my app and they get difficult to shut down. Even if I run the application again, it resumes to the google os but not my application code. I'm honestly confused and frustrated.
Under Add New Item - Solution Items it shows Installed and only has General, Performance, and Test Settings. Visual C# is not there even though I have the .NET and Windows workloads for C# install in addition to Mobile development with Xamarin. VS 2017 15.4.0 Community. In the about, Visual C# 2017 shows.
on 2019 version is almost the same but can happend listview will not show the data. For fix it in app.xaml.cs file rewrite it to DB_PATH = database_Path for example and as App parameter do App(string database_path). Now everthing should work like in this tutorial
Why wont my TextCell Text="{Binding Name}" find that property of the NewBook class? The same for when i had to add "Newbook" before calling Name in AddBok.cs like this NewBook.Name. Im using VS2017.
Hello Eduardo i was following behind you, but when i tried to set this.db_path in 44:37 it doesn't work, it says member 'app.DB_PATH' cannot be accessed with an instance reference; qualify it with a type name instead.
I made an app using this tutorial, I archived it in release mode (followed some other tutorials on how to make an APK file), I install it on my phone, but when I try to open it it shows a white screen for like half a second then closes. What do I do wrong!? PLEASE HELP

When you describe partial class you say it is defined in 2 files - cs and xaml. This is not quite correct. It is defined in 2 files - both cs and the second one is designer file. Right click on function InitializeComponent and select GoToDefinition. You end up in different file. This is the second file where partial page is defined
Followed your video and made projects twice now and took care about the code, restarted the first project several times, but the app fails to start since running it at 01:03:21.
I am trying to learn mvvm and this seems to go against that paradigm by using code behind. Every official Xamarin tutorial I have watched strongly discourage using code behind.
Thank you so much. This is an excellent tutorial to get someone started building mobile apps in C# and XAML. Question for you: Is it best to create a single Connection object that is public and persists throughout the application''s life? Or to create a new Connection object every time an interaction with the database is required? (I will be using SQL Server Express and eventually migrating to SQL Server proper.) Many thanks again
Gracias!!! muy buen curso! Solamente queria hacerte una pregunta; si quiero limpiar los datos de la DB, cómo puedo hacer? De todas maneras, estaré buscando e investigando
When you use a software let's say Xamarin and you get some errors from the start and everyone says that the way to fix these errors is by reinstalling the software, well that's when you realize that you're smart enough never to use this shite again...
Truly Awesome. I could follow and run it live on my Android Phone 100%. This is my first introduction to Xamarin Forms. I just want to know if it is possible run the IOS app directly on an iOS Phone instead of connecting to a Apple Computer first.
Bro, this is the wrong video to start learning coding. Cross-platform development is complex even for experienced programmers. Start with basics and give it time to sink in.
Yeah dude, to think that this is the place to first start to learn programming is absolutely stupid to say the least... Learn a computer language like Jave or C first. And even then there are still much more things to learn before you move one to a cross platform mobile development language.
Eduardo, I'm having an issue. I've done basically all you've shown in the video, leading up to building the app (30:40). Whenever I do this, the emulator displays nothing. Then when I close it, the error message "There were deployment errors. Continue?" shows up. The build fails once that pop-up message displays and the error is only a warning "ID0006. Error encountered while loading the project. Some project features, such as full solution analysis for the failed project and projects that depend on it, have been disabled" How can I fix these issues? Great video by the way. Very helpful.
Awesome Job Eduardo!!! I am JUST starting out and one of my first projects will be to do a database, but in my case it will be on a server or in the cloud and this answers a TON of questions I had. Keep up the good work and I look forward to more videos by you!
Oh boy, you're amazing! You teach so well and finally i could understand why i got so much issues with forms and what i was doing wrong, thank you so much for the video, everything worked properly i'm so happy!
Hi eduardo, great video. The "Binding" feature in Listview~TextCell doesn't seem to work in the newest release of Xamarin Forms There isn't a drop down list of functions when i type
Hey, I'm already stuck at the start just on rebuilding the solution, you say that it gets 2 succeeded and 1 skip yet I get 1 succeeded, 1 failed and 1 skipped
Thank you so much! I am coming from the Python world and having tutorials like this that talk through the logic really help a lot to connect the dots using a new language. Thanks again!
No hay manera que yo pueda llegar a correr una aplicacion en Visual Studio 2017 Community. Yo fui a un evento de Microsoft y ni siquiera ellos pudieron ayudar con los errores que salian...
@@EduardoRosasOsorno yo siempre he usado visual studio para Windows Forma, luego WPF y MVC sin problemas. pero desde que Xamarin salió hasta ahora no hay manera que yo de pie con bola con ello. Uno de los problema que tengo es con el emulador. Se abre pero no corre. El segundo problema es con el Android SDK. Abrí el SDK Manager e instale el Android Pie y ahora me da error. El emulador que tiene dice Oreo 8. A lo mejor eso es. El tercer problema es que todo cambio y ahora en Cross Platform solo hay una opción y la opción Portable ya no dice Portable. Aunque los archivos parecen ser los mismos. Yo puedo vivir con eso. El último problema es que no tengo un Previewer. Microsoft looking saco de VS en la última versión. Ahora hay algo que descargas una aplicación en el teléfono y Lee un QR Code y así es como lo ves directo del teléfono. Pero ya esa ventana que ponías al lado para ver los cambios en el xaml no existe.
Ya pude arreglar todos los problemas. Basicamente todo era culpa de el SDK Manager que no tenia los SDK necesarios. Fui a Tools - SDK Manager e instale todo desde Android 4.4.4 KitKat hasta la ultima Android Pie 9. Gracias por la explicacion del Previewer. Me ayudo a encontrarlo bien facil!
I have followed your tutorial and made a small application. But when I write code to set Itemsource to ListView, my build is failing saying that Listview not found in this context. Please do help me to resolve the same. I am beginner and first timer on xamarin.
17:40 The base class associated with this Xaml file could not be found. Please double check the class referenced in the "Class" atrtribute exists, and that the project has been compiled ?

what a sad new year for me :'(
It's ridiculous how bad it is.
I noticed its lame
I read somewhere, I don't remember where... that they were encouraging the use of commands.
Hi Eduardo! I was able to follow your tutorial and everything worked perfectly. For the first time things started clicking, thanks to the way you teach. Miguel de Icaza would be proud of you. :)
I'm heading to your udemy page for the complete Xamarin course. All the best! Thank you!
Wouldn't it be nice if the guys at Microsoft would not be radically changing everything every couple of months? I think it would...
For the windows version UWP i.e. why i came here
string fileName = "books_db.sqlite";
string fileLocation = Windows.Storage.ApplicationData.Current.LocalFolder.Path;
string full_path = Path.Combine(fileLocation, fileName);
LoadApplication(new MyBooks.App(full_path));
Thanks alot! Do you have any idea on how you would be able to remove inputs from the list?
i'm getting errors. In the SaveClick method,when i type DisplayAlert(.......); It says "does not exists in the current context" help!
thank you for this video, i wished that you did also 'update, delete and search' then you will complete all things. thank you again.
By far, one the of the beginner friendly Xamarin tutorials on youtube, still packing a lot of content, that can make you launch your first app
Much Appreciated ("Ka Leboga" in Setswana) Eduardo - to think I was lazy to go thru the entire video

This for tutorial am new Xamarin . i am android developer . i am little bit confuse In Xamarin we wright different -different code for android & IOS
When i wrrite
..... in MainPage.xaml does not apear in MainPage.xaml.cs ....why?
Hope you can make a video on how to make a Point of Sale Application. Thanks!

Sudipto Kumar Mukherjee not exactly, you could try using the Xamarin Live Player, but a Mac is required to run the app directly
I give up. I don't understand any of the logic of coding.
dont give up bro, it is really worth it once you get into it, and isnt that complicated once you wrap your head around the basics
Start by learning OOP programming fundamentals
Bro, this is the wrong video to start learning coding. Cross-platform development is complex even for experienced programmers. Start with basics and give it time to sink in.

@@quicksilver1752 I think learning java is more useful than C.

Hi eduardo, great video.
The "Binding" feature in Listview~TextCell doesn't seem to work in the newest release of Xamarin Forms
There isn't a drop down list of functions when i type
JChan1026 nothing wrong, there is no autocompletion of the TextCell, but you should be able to run the app and see the cells being displayed

Thank you so much! I am coming from the Python world and having tutorials like this that talk through the logic really help a lot to connect the dots using a new language. Thanks again!
What if there is no PCL option?
.NET standard.
Excellent tutorial!, thank you

I'm having the same problem, any help ??
It was hard to find a sulotion for this just by googleing, found nothing yet. And I switched to Xcode, sry bud :[
First start the emulator from the Android Device Manager, and after you have a running emulator click on the green triangle =)
Great tutorial ! Very clear ! Nice Job !
Great explanation!!!!!! I will take the full course
Great tutorial Eduardo, thank you very much
40:01 reminder for myself
No hay manera que yo pueda llegar a correr una aplicacion en Visual Studio 2017 Community. Yo fui a un evento de Microsoft y ni siquiera ellos pudieron ayudar con los errores que salian...
Eso suena mal, qué errores te salían? Yo he usado Visual Studio 2017 Community sin problemas.
@@EduardoRosasOsorno yo siempre he usado visual studio para Windows Forma, luego WPF y MVC sin problemas. pero desde que Xamarin salió hasta ahora no hay manera que yo de pie con bola con ello.
Uno de los problema que tengo es con el emulador. Se abre pero no corre.
El segundo problema es con el Android SDK. Abrí el SDK Manager e instale el Android Pie y ahora me da error. El emulador que tiene dice Oreo 8. A lo mejor eso es.
El tercer problema es que todo cambio y ahora en Cross Platform solo hay una opción y la opción Portable ya no dice Portable. Aunque los archivos parecen ser los mismos. Yo puedo vivir con eso.
El último problema es que no tengo un Previewer. Microsoft looking saco de VS en la última versión. Ahora hay algo que descargas una aplicación en el teléfono y Lee un QR Code y así es como lo ves directo del teléfono. Pero ya esa ventana que ponías al lado para ver los cambios en el xaml no existe.
Ya pude arreglar todos los problemas. Basicamente todo era culpa de el SDK Manager que no tenia los SDK necesarios. Fui a Tools - SDK Manager e instale todo desde Android 4.4.4 KitKat hasta la ultima Android Pie 9. Gracias por la explicacion del Previewer. Me ayudo a encontrarlo bien facil!
Best getting started video yet. Thanks and keep it up!

I have followed your tutorial and made a small application. But when I write code to set Itemsource to ListView, my build is failing saying that Listview not found in this context. Please do help me to resolve the same. I am beginner and first timer on xamarin.
Hey, I had the same problem. I fixed it by: Rebuild solution, and then try and then it should be accessible
René Schmidt but problem is for every control we add we need to build. Because I'm new to this development it will be very hard to build all time.
Im new to this kind of development also - however, I'm familiar with C# and windows forms :) so it's still kinda different for me :)
Haha, love the title... liked!
Speed it up @ 1.25

17:40 The base class associated with this Xaml file could not be found. Please double check the class referenced in the "Class" atrtribute exists, and that the project has been compiled ?
Hey man I'm having the same problem, did you find a solution to it?
NVM i found out how to fix it. You have to rebuild the ENTIRE SOLUTION PROJECT, after that you have to then rebuild MyBooks again, then it will work.
Thank you
Excellent
Thanks
Previewer is gone!
Perhaps this can help: lalorosas.com/blog/where-the-hell-did-the-xamarin-forms-previewer-go
@@EduardoRosasOsorno Thank you. This really helped me. Microsoft always changing stuff around without letting us know!
at 21:20 for me the new event handler doesnt fire up
Same for me. Any fix for this? Its pretty frustrating that you have to type in the C# eventhandler part manually.
Intellisense is broken in new VS install an older version if you can developercommunity.visualstudio.com/content/problem/167039/intellisense-completely-broken.html
Hello @Eduardo Rosas, thank you very much for this great tutorial! It's brilliant.
Thank you @TZCoder, I will try this out.
Kind regards.
Use commands instead.
Get to the point. Gosh, almost 20 minutes before anything happens....
I followed this but I get an exception error when I try to save at:
using (SQLite.SQLiteConnection conn = new SQLite.SQLiteConnection(App.DB_PATH))
Unhandled Exception:
System.ArgumentException: Must be specified
Parameter name: databasePath occurred
Fixed it! I had LoadApplication(new App()); instead of LoadApplication(new App(full_path));
so did your application run after changing these fore mentioned errors?
Important: Set the speed to AT LEAST 1.5 (i did 2) or you will be frustrated from wasting time on all the redundant information.
Also: This does not allow you to add a service reference.
