compilation gives error SYSLIB1094 for a GeneratedComInterface interface deriving from an interface in another project

[smourier]

Description

I have two projects, one console app project, referencing another class library project. One interface IMy is declared in the class library, and another interface IMy3 is declared in the console app and derives from IMy

Both projects are using ComWrappers source generation feature (GeneratedComInterface).

I cannot compile the console application.

Reproduction Steps

Here the class library project:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<TargetFramework>net8.0</TargetFramework>
		<ImplicitUsings>enable</ImplicitUsings>
		<Nullable>enable</Nullable>
		<AllowUnsafeBlocks>True</AllowUnsafeBlocks>
		<PublishAot>true</PublishAot>
	</PropertyGroup>
</Project>

Contains only one file IMy.cs:

using System.Runtime.InteropServices;
using System.Runtime.InteropServices.Marshalling;

namespace AotTest
{
    [GeneratedComInterface, Guid("68207504-314f-492a-b4f2-fbc1838e6ac3")]
    public partial interface IMy
    {
    }

    [GeneratedComInterface, Guid("80511349-dff5-4c5e-839b-af4735977ebf")]
    public partial interface IMy2 : IMy // this derived one works fine
    {
    }
}

Here's the console app project:

<Project Sdk="Microsoft.NET.Sdk">
	<PropertyGroup>
		<OutputType>Exe</OutputType>
		<TargetFramework>net8.0</TargetFramework>
		<ImplicitUsings>enable</ImplicitUsings>
		<Nullable>enable</Nullable>
		<PublishAot>true</PublishAot>
		<AllowUnsafeBlocks>True</AllowUnsafeBlocks>
		<InvariantGlobalization>true</InvariantGlobalization>
	</PropertyGroup>

	<ItemGroup>
		<ProjectReference Include="..\AotTest\AotTest.csproj" />
	</ItemGroup>
</Project>

contains only one file Program.cs:

using System.Runtime.InteropServices;
using System.Runtime.InteropServices.Marshalling;

namespace AotTest.Cli
{
    internal class Program
    {
        static void Main()
        {
            Console.WriteLine("Hello, World!");
        }
    }

    [GeneratedComInterface, Guid("755293e8-fe80-4654-aee3-732fefaaf3e0")]
    public partial interface IMy3 : IMy
    {
    }
}

Expected behavior

I don't see why it shouldn't compile, I hope this simple scenario is supported.

Actual behavior

I get compilation error:

1>------ Build started: Project: AotTest, Configuration: Debug Any CPU ------
1>AotTest -> E:\smo\work\AotTest\AotTest\bin\Debug\net8.0\AotTest.dll
2>------ Build started: Project: AotTest.Cli, Configuration: Debug Any CPU ------
2>E:\smo\work\AotTest\AotTest.Cli\Program.cs(15,30,15,34): error SYSLIB1094: COM interface AotTest.Cli.IMy3 inherits from AotTest.IMy, which has errors. ComInterfaceGenerator will not generate source for AotTest.Cli.IMy3. (https://learn.microsoft.com/dotnet/fundamentals/syslib-diagnostics/syslib1094)
2>Done building project "AotTest.Cli.csproj" -- FAILED.
========== Build: 1 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Also, independently from the SYSLIB1094 error, Roslyn seems to crash (but not always, seems more a background thing) this is what I see (sometimes) in Visual Studio and it seems somehow related (I have a bigger project where these top error lines popup continuously):

Here is the stack trace from the first error line:

Regression?

I don't tink so but I can't be sure.

Known Workarounds

I don't have any.

Configuration

.NET 8.0.5, Visual Studio 17.10.0 (latest), Windows 11 x64
