Looking forward to the next video that covers paging, filtering and sorting with this new method.

3:50 When using .AddType(), then throw error - 'Query': static class type cannot be used as type arguments

[@rpreviato]

Why when I use AddType(); I get the following error?
"The call is ambiguous between the following methods or properties: 'SchemaRequestExecutorBuilderExtensions.AddTypes(IRequestExecutorBuilder, params Type[])' and 'SchemaRequestExecutorBuilderExtensions.AddTypes(IRequestExecutorBuilder, params INamedType[])'"

[@razvangoia800]

How would this work if the query type is in a different project in the solution, having a hard getting the AddTypes to detect the query

[@douglaswoods3869]

Where can I find the code for this example? Looks really good, but having the sample code would make life much easier for the humble user of hot chocolate

Just followed this guide but I am still getting the following error: "A second operation was started on this context instance before a previous operation completed."
Did something change?

[@dandoescode]

Why does the AssetRepository need to be registered twice? Is there any way that can be made more succinct?
Look forward to seeing the follow-up video. 🙂

[@ChilliCream]

No,
You register it ones with the DI. But if you want to use it without attribute then you need to register it as well-known services with the GraphQL configuration as well.
Hot Chocolate resolves services through the IServiceProvider interface we have no way of inspecting what services are available through that interface. Nor can we see how they can be used.
Either use the service attribute, register it with the GraphQL configuration or write a parameter expression builder that can identify your services.
