COM+ and .NET

[Guest]

I have written a COM+ server and it works fine with vb 6.0 clients, but it
does not with .NET clients.

For the COM + server, I created a Class Library project and a COM class
inside. Inside the COM class I wrote a function. I built the project and
generated the COMserver.dll and COMserver.tlb files (If I try to do this with
the .dll file I get the message "One or more files do not contain components
or type libraries. These files cannot be installed"). All was OK.

I created an COM+ Application in my machine and I installed a new component
with the COMserver.tlb file. All was OK.

After, I created a Windows application client with VB 6 which called the
component I have already created. It all was OK again.

Finally I created a Windows application client with VB .NET and when I tried
to register the COMserver I got the message:

"A reference to 'COMserver' could not be added. Converting the type library
to a .NET assembly failed. Type library COMserver was exported from a CLR
assembly and can not be re-imported as a CLR assembly"

I hope some of you can help me. Thanks

Hi there... Make sure your COM's references are present in the machine from
which you're trying to create your .NET Windows App. Regards.

They are present. At least I can create then COM Application with Component
Services and VB 6 and VB.NET list it as a COM Component. In fact, the VB t6
client works fine.

I could solve my problem referencing EnterpriseServices and derivating my
classes from ServicedComponent (look at
http://www.15seconds.com/issue/030501.htm for details).

Now, I want to use COM+ role based security for my methods, but Component
Services does not show me my class methods. I mean, I can see my components,
their interfaces, but below those interfaces I can't see any method.

Any idea?
