Dude, ur video is amazing! Ur explained everything so smoothly, in a way that as long as u speak, u keep incrementally expanding examples, showing how everything works and proving ur point . Congratz, dude. One more sub !
Wow thank you Bruno for your kind words. This is exactly what I aim to achieve with each of my videos. Hope you are enjoying the playlist bit.ly/aws-net-series
Hi Rahul, great video! You have helped alot throughout the last 6 months or so. I am having an issue where my lambda function works locally but it doesn't work on the aws lambda section. The error I'm getting is 'Reason: No parameterless constructor defined.' It seems it's not looking for the serverless.template file as an entry point and instead is trying to instantiate the 'Function' class (which is where my Function Handler is). i don't have a paremeterless constructor because I'm injecting my dependencies there.
Hey Gabriel Glad you are liking the content. Are you using the Lambda Annotations framework and have setup the Startup class etc appropriately? The entry point might be pointing to the actual class instead of the auto-generated class name that the annotations fwk generates. You can see in the example here that the entry point is a generated class. github.com/rahulpnath/youtube-samples/blob/main/LambdaAnnotationSample/LambdaAnnotationSample.FromScratch/serverless.template Let me know if that helps - if not you can reach me on email with more details and probably a demo app (details in About page)
@@RahulNath Thanks for the response. I am currently utilizing the lambda annotations framework and have configured both the startup class and function handler functions with the appropriate annotations. For local testing, I'm employing the Test Mock Lambda tool, which seamlessly works with injected services. Upon inspecting the .ddl file utilized by the AWS console using dotPeek, I observed that it mirrors the files generated locally in the bin/debug folder, including the presence of the serverless.template file accurately referencing the generated class serving as an entry point. My suspicion arises from the possibility that my company utilizes Terraform to orchestrate the AWS cloud infrastructure. Within the Terraform module for Lambda, they specify the handler. In this context, the handler points directly to the actual class, resembling something like: MyProduct.Functions.Submission::MyProduct.Functions.Submission.Function::FunctionHandler. I speculate that if I were to request a modification of the handler to reference the generated class defined in the serverless.template, akin to: MyProduct.Functions.Submission::MyProduct.Functions.Success.Function_FunctionHandler_Generated::FunctionHandler, it would likely function as expected. This assumption aligns with my understanding that the true entry point is the function inside the _Generated.cs file, defined in the serverless.template file. Correct me If I'm wrong regarding the true entry point. Regarding your example showcased in the video, subsequent to integrating your FromScratch project with lambda annotations, does the handler in the Lambda section of the AWS console alter to: LambdaAnnotationSample.FromScratch::LambdaAnnotationSample.FromScratch.Function_MathPlus_Generated::MathPlus? In your Lambda annotations video, before integrating with lambda annotationjs, it is set to -> LambdaAnnotationSample.BeforeAnnotations::LambdaAnnotationSample.BeforeAnnotations.Function::MathPlus. The video in question is this one: th-cam.com/video/qWxjCkqX_lM/w-d-xo.html, at exactly the 3 minute mark.
@RahulNath I missed this but at the 16:29 minute mark in the current video, it did in fact change the handler to the generated file LambdaAnnotationsSample.FromScratch::LambdaAnnotationsSample.FromScratch.Function::MathPlus_Generated::MathPlus. I will request this change in the handler of the terraform modules. Thank you for this, I have learned alot from you. My sincerest respect goes out to you.
Maybe someday you can make a video on how to use different environments (or Stages, development or production in example) and how to deploy them using Lambda Annotions Framework.

Do you recommend Singleton or Transient with repository class that work with data?

Great let me know how this goes and hope you are able to resolve your problem. Do let me know if you have any topic suggestions.
Maybe someday you can make a video on how to use different environments (or Stages, development or production in example) and how to deploy them using Lambda Annotions Framework.
Thank you Mariano for the feedback. What would you like to see in that video? Anything you are particularly stuck with?
Great video and very much clear. Do you have any plan to make some video on how to deploy .NET Core WEB API into AWS EKS and scale accordingly ?
How can we work with EF and Lamda?
In this case will the dbcontext be singleton if injected in function constructor or an interface
