Hi all,

I'm writting a Custom Tool in C# for VS 2005 by implementing IObjectWithSite
and IVsSingleFileGenerator. I based my code on the gotdotnet
BaseCodeGeneratorWithSite sample which I'm trying to migrate to VS 2005 with
no success. My problem is I cannot find the assembly that declares
IVSMDCodeDomProvider interface.

I found this interface in Microsoft.VisualStudio.Designer.Intefaces.dll and
all works fine if I reference this assembly. But this assembly is for VS
2003 and I'm using VS 2005.

I also tried to declare the inteface myself:

[ComImport, Guid("73E59688-C7C4-4A85-AF64-A538754784C5"),
InterfaceType((short) 1)]
public interface IVSMDCodeDomProvider
{
     [DispId(0x60010000)]
     object CodeDomProvider { [return: MarshalAs(UnmanagedType.IDispatch)]
[MethodImpl(MethodImplOptions.InternalCall,
MethodCodeType=MethodCodeType.Runtime)] get; }
}

But I'm not an Interop guy and I got InvalidCastException in the following
line of code:

IVSMDCodeDomProvider vsmdCodeDomProvider =
(IVSMDCodeDomProvider)GetService(CodeDomInterfaceGuid);
