Description
I've tried to use the new configuration binder source generator to bind a type that contains a custom collection of abstract types.
I got following error:
C:\Users\adsitnik\source\repos\ConfigBindRepro\Microsoft.Extensions.Configuration.Binder.SourceGeneration\Microsoft.Extensions.Configuration.Binder.SourceGeneration.ConfigurationBindingGenerator\BindingExtensions.g.cs(61,29): error CS0
103: The name 'InitializeEndPoint' does not exist in the current context [C:\Users\adsitnik\source\repos\ConfigBindRepro\ConfigBindRepro.csproj]
I would expect it to not produce a compiler error and just try to map what it can, without throwing an exception at runtime (this is what the reflection based binder does in this case).
