I still get this AndArgumentsMatch exception after applying patch TypemockIsolatorSetup_602_q273.msi.

Here's the production code

    public interface ISpectralResponseCurve
        double SpectralAcceleration(double period, double dampingRatio);
        double SpectralDisplacement(double period, double dampingRatio);

And here's the test code:

    var curve = Isolate.Fake.Instance<ISpectralResponseCurve>(Members.CallOriginal, ConstructorWillBe.Ignored);
            Isolate.WhenCalled((double period, double dampingRatio) => curve.SpectralAcceleration(0, 0))
                .AndArgumentsMatch((period, dampingRatio) => period == 1.0).WillReturn(0.85 * 386.4);

The exception I got was:

failed: TypeMock.TypeMockException :
*** All argument matching parameters should be used on the same method.
at hd.a()
at hd.a(Int32& A_0)
at f6.d()
at c8.a(Boolean A_0)
at dd.b(Boolean A_0)
at ib.c(Boolean A_0)
at ib.a(Object A_0, Boolean A_1, Func`1 A_2, Action A_3, Action A_4, Action A_5)
at ib.c(Object A_0)

Any idea?

Hi Soon Hui,

When matching arguments, all argument matching variables (the ones you pass in to the WhenCalled() lambda expression) need to be used on the same method in the expression. In this statement:
Isolate.WhenCalled((double period, double dampingRatio) => curve.SpectralAcceleration(0, 0))... 

the variables period and dampingRatio are not used. Replacing that call with the following should work:
Isolate.WhenCalled((double period, double dampingRatio) => curve.SpectralAcceleration(period, dampingRatio))
