Hi All,

I'm trying to generate a C# wrapper for a Windows type library using the
following command line ...

csc /target:library /doc:Interop.MyLibrary.xml /unsafe Interop.MyLibrary.cs

And receiving the following error message ...

Interop.MyLibrary.cs(499,18): error CS0536:
'Interop.MyLibrary.IImpBaseCollection_SinkHelper' does not implement
interface member 'Interop.MyLibrary.IImpBaseCollection.Item(object)'.
'Interop.MyLibrary.IImpBaseCollection_SinkHelper.Item(object)' is either
static, not public, or has the wrong return type.

Here's the code....

(Line 499
Any ideas appreciated!! ;-)

Thanks,
Roland
