Description
I found code that throws a VerificationException for static virtual interface methods, and generic constraints, similar to this issue #73658 but without reflection.
Reproduction Steps
Run this code:
public interface ITestItem<T>
{
}
public interface IStaticInterfaceBase<T, in TRequest>
where T : class
where TRequest : IStaticInterfaceBase<T, TRequest>
{
static abstract void TryInvoke<TItem>(TItem item, TRequest request) where TItem : ITestItem<T>;
}
public interface IStaticInterface<T, in TRequest> : IStaticInterfaceBase<T, TRequest>
where T : class
where TRequest : IStaticInterface<T, TRequest>
{
static void IStaticInterfaceBase<T, TRequest>.TryInvoke<TItem>(TItem item, TRequest request)
{
}
}
public class Request : IStaticInterface<object, Request>
{
}
internal class Program
{
public static void Invoke<T, TRequest>(TRequest request)
where T : class
where TRequest : IStaticInterfaceBase<T, TRequest> =>
TRequest.TryInvoke((ITestItem<T>) null!, request);
public static void Main(string[] args) => Invoke<object, Request>(new Request());
}Expected behavior
The code will run without error.
Actual behavior
Unhandled exception. System.Security.VerificationException: Method StaticInterfaceBug.IStaticInterface`2[System.Object,StaticInterfaceBug.Request].StaticInterfaceBug.IStaticInterfaceBase<T,TRequest>.TryInvoke: type argument 'TItem' violates the constraint of type parameter 'TItem'.
