❔ Source Generator does not work in .NET CLI

When I compile my project in Rider, everything works fine:

2>------- Finished building project: WebFormsCore.NativeAOT.Example. Succeeded: True. Errors: 0. Warnings: 0

2>------- Finished building project: WebFormsCore.NativeAOT.Example. Succeeded: True. Errors: 0. Warnings: 0

but when I try to build it with the CLI (dotnet build or dotnet publish), I get the following:

Build FAILED.

C:\Sources\WebForms\examples\WebFormsCore.NativeAOT.Example\Program.cs(12,10): error CS1061: 'ServiceCollection' does n
ot contain a definition for 'AddAssemblyControls' and no accessible extension method 'AddAssemblyControls' accepting a
first argument of type 'ServiceCollection' could be found (are you missing a using directive or an assembly reference?)
 [C:\Sources\WebForms\examples\WebFormsCore.NativeAOT.Example\WebFormsCore.NativeAOT.Example.csproj]

first argument of type 'ServiceCollection' could be found (are you missing a using directive or an assembly reference?)
 [C:\Sources\WebForms\examples\WebFormsCore.NativeAOT.Example\WebFormsCore.NativeAOT.Example.csproj]

In my .csproj I included the source generator with a project reference:

<ProjectReference Include="..\..\src\WebFormsCore.SourceGenerator\WebFormsCore.SourceGenerator.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />

<ProjectReference Include="..\..\src\WebFormsCore.SourceGenerator\WebFormsCore.SourceGenerator.csproj" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />

The source generator generates the following:

namespace WebFormsCore.NativeAOT.Example
{
internal static class ControlsServiceProviderExtensions
{
    public static void AddAssemblyControls(this global::Microsoft.Extensions.DependencyInjection.IServiceCollection services)
    {
        global::Microsoft.Extensions.DependencyInjection.ServiceCollectionServiceExtensions.AddTransient<WebFormsCore.NativeAOT.Example.Test, WebFormsCore.NativeAOT.Example.CompiledViews.Test_aspx>(services);
        global::Microsoft.Extensions.DependencyInjection.ServiceCollectionServiceExtensions.AddTransient<WebFormsCore.NativeAOT.Example.CompiledViews.Test_aspx>(services);
    }
}
}

namespace WebFormsCore.NativeAOT.Example
{
internal static class ControlsServiceProviderExtensions
{
    public static void AddAssemblyControls(this global::Microsoft.Extensions.DependencyInjection.IServiceCollection services)
    {
        global::Microsoft.Extensions.DependencyInjection.ServiceCollectionServiceExtensions.AddTransient<WebFormsCore.NativeAOT.Example.Test, WebFormsCore.NativeAOT.Example.CompiledViews.Test_aspx>(services);
        global::Microsoft.Extensions.DependencyInjection.ServiceCollectionServiceExtensions.AddTransient<WebFormsCore.NativeAOT.Example.CompiledViews.Test_aspx>(services);
    }
}
}

and in code I do the following:

services.AddAssemblyControls();

services.AddAssemblyControls();

I tried both net8.0 (preview 2) and net7.0, with and with-out <PublishAot>true</PublishAot>. What am I missing? Should I try to remove the preview SDK and see if it works..?

Ah, for now I found a work-around for my initial problem. I couldn't use Activate.CreateInstance on my type. So I've added the following:

[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)]

[DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicConstructors)]

on the assembly attribute that registers the control. ThinKenobi

Looks like nothing has happened here. I will mark this as stale and this post will be archived until there is new activity.
