[MiYanni]

Summary

In dotnet/sdk, there were 2 tests marked against this original issue. That issue has been closed, but unskipping the tests still results in failure. This is to investigate those test failures.

TestInterfaceWithOperatorGeneration

Fails with:

    Expected:
    namespace A
    {
        public partial interface IntType
        {
            public static IntType operator +(IntType left, IntType right) => left + right;
        }
    }
    Resulted:
    namespace A
    {
        public partial interface IntType
        {
            static public IntType operator +(IntType left, IntType right) { throw null; };
        }
    }

TestInterfaceWithCheckedOperatorGeneration

Fails with:

    Expected:
    namespace A
    {
        public interface IAdditionOperators<TSelf, TOther, TResult>
            where TSelf : IAdditionOperators<TSelf, TOther, TResult>?
        {
            static abstract TResult operator +(TSelf left, TOther right);
            static virtual TResult operator checked +(TSelf left, TOther right) { throw null; }
        }
    }
    Resulted:
    namespace A
    {
        public partial interface IAdditionOperators<TSelf, TOther, TResult>
            where TSelf : IAdditionOperators<TSelf, TOther, TResult>?
        {
            static public abstract TResult operator +(TSelf left, TOther right) { throw null; };
            static public virtual TResult operator checked +(TSelf left, TOther right) { throw null; };
        }
    }

Can you expand on what you think is a bug in the compiler?
