Can I use nested class with events?

[MWK]

Hi All,

I use VS2003 and managed code to compile a DLL.
When I use a nested class, the event always cause an error:

LINK : error LNK2020: unresolved token (06000004)
Test.TestClass::OnEventFired
LINK : fatal error LNK1120: 1 unresolved externals

If I remove the nested class, everything goes fine.
Here is the class structure, can some one please tell me what's wrong with
the code.

namespace Test
{
public __gc class TestClass
{
public:
TestClass()
{ }

public:
__event void OnEventFired(TestClass* sender, String* Data);

///
/// something here to raise the event
///
//hereis the nested class
__gc class NestedClass
{
public:
NestedClass()
{ }
};

};
}
