Description Thomas Smith 2013-03-29 19:12:38 UTC
The following code is syntatically correct, but won't compile with Mono (it compiles fine in Visual Studio).

    public enum TestEnum { A, B, C };

    public abstract class TestClass<T>
    {
        public TestClass()
        {
            Test0();
            Test1();
            Test2();
        }

        public void Test0() { }

        public void Test1(TestEnum param = TestEnum.A) { }

        public void Test2() { }
    }

The compiler errors at the Test1 and Test2 calls in the constructor:

  error CS0103: The name `Test1' does not exist in the current context
  error CS0103: The name `Test2' does not exist in the current context

The compiler seems unable to locate the Test1 and Test2 methods in this case. It's capable of locating the Test0 method though (order seems to matter?). Doing one of the following things allows the code to compile:
- moving the Test2 declaration above Test1
- removing the template on the class
- removing the default value for the parameter "param" of Test1
- changing the type of parameter "param" to a non-enum type

Already fixed in Mono 3.0
