yield-return decompiler failed

[CreateAndInject]

Original:

        public static IEnumerable<int> Enumerate()
        {
            for (int i = 0; i < 10; i++)
            {
                int result;
                try
                {
                    result = DateTime.Now.Second;
                }
                catch
                {
                    continue;
                }
                yield return result;
            }
        }

ILSpy:

[IteratorStateMachine(typeof(<Enumerate>d__1))]
public static IEnumerable<int> Enumerate()
{
	//yield-return decompiler failed: Unexpected instruction in Iterator.Dispose()
	return new <Enumerate>d__1(-2);
}

But my target is .NET Framework 3.5 rather than .NET 9

Seems compiler change something, ILSpy doesn't work even if such code:

        public static IEnumerable<int> Enumerate()
        {
            for (int i = 0; i < 10; i++)
            {
                yield return i;
            }
        }

Yes, exactly, from time to time, the roslyn team is changing their code gen a bit and we need to update the decompiler to support that. Unfortunately, currently there is no publicly available nuget package containing these changes. Usually we update our decompiler tests to always include the latest version of the compiler, but we only can do that if there is a nuget available. Usually, the package is updated in time with each release of VS, but it seems that this time, they take longer to publish the packages. I'd prefer to wait for the official release from nuget to be able to test all the language features at once, without having to resort to hacks or manually writing tests, because it is more time consuming than just following our usual procedure.

Thank you for your understanding.
