Here is an example how to use WhenCalled in order to ignore (stub) a private call:
Copy
[TestMethod]
[Isolated]
public void StubPrivateMethod_DoNotWriteToDisk()
{
    RealLogger fake = Isolate.NonPublic.Fake.Instance(typeof(RealLogger));

    // Avoid performing actual write to disk by ignoring (stubbing) a private call
    Isolate.NonPublic.WhenCalled(fake, "WriteToDisk").IgnoreCall();

    // The private call is stubbed so no actual disk writes are performed
    fake.Log("Hello World");

    Assert.AreEqual(1, fake.LineCount);
}
