Attempt to run the tests above with JustMock profiler enabled fails with System.InvalidProgramException. The issue is not reproducible with MSTest.TestFramework and MSTest.TestAdapter packages prior to 3.0.x.

public void ValidParameters_Success(int param1, int param2)
{
	// Arrange
	Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);

        // Act
	IService service = new Service();
	bool result = service.method2();

	// Assert

	Mock.Assert(() => MyClass.method1(), Occurs.Once()); // <-- the test fails here because it reports that method invocation occurs twice
}

The issue in not observed if the code is modified in the following way, which indicates behavioral incinsistency:

public void ValidParameters_Success(int param1, int param2)
{
	// Arrange
	Mock.SetupStatic(typeof(MyClass), Behavior.Strict, StaticConstructor.Mocked);

        // Act

	bool result = service.method2();

	// Assert

One of the possible workarounds is to create a mock like this:

...
var cultureInfo = Mock.Create(() => new CultureInfo(cultureName));

The test passes, but the debug trace output contains the warning message: "Calling one test method from another could result in unexpected behavior and must be avoided. Extract common mocking logic to a non-test method." even there is no call to the other test methods.
