IsAny() not matching where it should?

[jez9999]

So I've been trying to verify if my .NET Core 3 ILogger mock has been called in my Assert phase, and the following successfully throws if my test method logs an error or a critical:

    _weatherLoggerMock.Verify(logger => logger.Log(
        It.IsIn(new LogLevel[] { LogLevel.Error, LogLevel.Critical }),
        It.IsAny<EventId>(),
        It.IsAny<It.IsAnyType>(),
        It.IsAny<Exception>(),
        It.Is<Func<It.IsAnyType, Exception, string>>((v,t) => true)
    ), Times.Never(), "Logger was called with Error or Critical!");

However, the following doesn't throw:

    _weatherLoggerMock.Verify(logger => logger.Log(
        It.IsIn(new LogLevel[] { LogLevel.Error, LogLevel.Critical }),
        It.IsAny<EventId>(),
        It.IsAny<It.IsAnyType>(),
        It.IsAny<Exception>(),
        It.IsAny<Func<It.IsAnyType, Exception, string>>()
    ), Times.Never(), "Logger was called with Error or Critical!");

Is this correct behaviour? It looks like the two should be semantically identical; in both cases I'm saying that the parameter should match the given type, and match no matter what the value. Why doesn't IsAny match?

See #919 and the ILogger-related linked there.

See #919 and the ILogger-related linked there.

I did read that but I don't quite see how it answers this issue? The solution there can't use IsAny() either.

[stakx]

Again, very likely because of the nested It.IsAnyType. Have you seen #918 (comment)?

[jez9999]

Ah ok, I see now.

I'll close this as a duplicate of #918. If you think that's in error please post here again.
