Common Language Runtime detected an invalid program.

[kristof12345]

Hi!

I get an excepion when running my tests:
System.InvalidProgramException : Common Language Runtime detected an invalid program.

My test is:
// Set DateTime.Now
Shim dateTimeShim = Shim.Replace(() => DateTime.Now).With(() => new DateTime(2020, 1, 1).AddHours(1));

        PoseContext.Isolate(async () =>
        {
            Assert.Equal(new DateTime(2020, 1, 1).AddHours(1), DateTime.Now);

            var result = await Repository.IncrementVotes();
            Assert.Equal(1, result);

            result = await Repository.IncrementVotes();
            Assert.Equal(2, result);

            result = await Repository.CountVotes();
            Assert.Equal(2, result);
        }, dateTimeShim);

Thanks.
