Compiling ASP.NET MVC 1.0 on Mono.

[Tom Opgenorth]

Hello all,

For my own curiousity, I tried to compile the ASP.NET MVC 1.0 source
code on Mono 2.4.3 (Ubuntu 9.10 x64).  When I do so under either
MonoDevelop or xbuild, I get this error message:

Mvc/FormCollection.cs(24,6):   error CS0246:  The type or namespace
name `FormCollectionBinder' could not be found. Are you missing a
using directive or an assembly reference?

Now, FormCollectionBinder is an attribute that adorns the class
System.Web.MVC.FormCollection.  The declaration of
FormCollectionBinderAttribute is a private sealed class inside of
FormCollection.  If I move the code for this attribute outside of the
class declaration for FormCollection and then try to compile, there
seems to be no problems.

Could this be a bug with the compiler?  A simpler case is this:

using System;

namespace Test
{
        [MyAttribute]
        public class MyClass
        {
                private sealed class MyAttribute: Attribute
                {
                       
                }
                public void MyMethod()
                {
                  Console.WriteLine("Hello World!");
                }
        }
}

I could not get this to compile on Mono 2.4.3.  Or, is there something
special one must do to get this to compile?

Yes, and the bug was fixed after 2.4.3 was released.

A workaround is to move the attribute class outside its containing type.

I just ended up tweaking the ASP.NET MVC source and moved the code for the attribute outside the class, all is good now.
