I managed to reproduce the issue locally using Mono AOT LLVM configuration. Test case: using System;
namespace HelloWorld
{
public interface ITypeChecker
{
static abstract bool Test<T>();
}
public interface IHandler
{
bool Test<T>();
}
public class TypeChecker : ITypeChecker
{
public static bool Test<T>() => true;
}
public class Handler<TChecker> : IHandler where TChecker : ITypeChecker
{
public bool Test<T>() => TChecker.Test<T>();
}
internal class Program
{
private static void Main(string[] args)
{
var handler = GetHandler();
bool test = handler.Test<int>();
Console.WriteLine(test);
}
public static IHandler GetHandler() => new Handler<TypeChecker>();
}

@vargaz If cmethod is a static virtual method, the receiver's type is null. In such case, if klass is used instead of the receiver's type, the test case works. I am not sure if the /cc: @lambdageek |

The fix has been merged. We should verify if it resolves the customer issue. Additionally, a runtime test should be added if this scenario is not already covered by full AOT llvm job on the CI. |

Hi everyone! |
|
The issue has been merged into main after the RC1 snap and backported to .NET 8 branch (not RC1). At some point, it will flow into RC2 and GA. @SamMonoRT Please fill in with details if I missed something. |

You can either wait for RC2 or switch to Preview 7. I will check if we can backport it to the RC1 as well. |
