I have a class that I want to mock. The class has a method that returns an array of strings. I want to return a specific value from that method. I have tried to use the NullExpression class to return null, but I get the following error: "The type or namespace name 'NullExpression' could not be found (are you missing a using directive or an assembly reference?)" I have tried to add the Telerik.JustMock.Core.Castle.DynamicProxy.Generators.Emitters.SimpleAST namespace to the top of the file, but that does not seem to work. I have also tried to add the Telerik.JustMock.Core.Castle.DynamicProxy.Generators.Emitters namespace, but that did not work either. I have also tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns(null). I have tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns((string[])null). I have tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns(new string[0]). I have tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns(new string[] { }). None of these worked. I have also tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns(new string[] { null }). This one worked, but it is not what I want. I want to return an array of strings that are all null. I have also tried to use the Mock.Arrange(() => myClass.MyMethod()).Returns(new string[] { null, null, null }). This one worked, but
