.NET 3.5 的起订量 mocking 库是否与 mono 一起使用？

Question

I'm trying to use Moq on a Mono / .NET 3.5 Project using MonoDevelop for MacOS X

I've tried the sample C# code:

var mock = new Mock<IFoo>();
mock.Setup((foo => foo.DoSomething("ping"))).Returns(true);

With IFoo beeing:

public interface IFoo
{
    bool DoSomething(string a);
}

But I keep getting the following compiler errors on the mock.Setup line:

    Error CS1660: Cannot convert `lambda expression' to non-delegate type `System.Linq.Expressions.Expression<System.Action<Test.IFoo>>' (CS1660) (Test)
    Error CS1502: The best overloaded method match for `Moq.Mock<Test.IFoo>.Setup(System.Linq.Expressions.Expression<System.Action<Test.IFoo>>)' has some invalid arguments (CS1502) (Test)
    Error CS1503: Argument `#1' cannot convert `anonymous method' expression to type `System.Linq.Expressions.Expression<System.Action<Test.IFoo>>' (CS1503) (Test)

Am I doing something wrong or it´s just that Mono is not yet ready for Moq?

Add a reference to System.Core
