Thanks gellyfish, and thanks holli

To gellyfish: I'll intend to open my class to C# developer, that are very slow.Unfortunately I'm not so able to access a custom assembly via COM and Win32::OLE (can you provide some guideline?)

When you say that I must be conservative what you means ?

I never got an WSDL to run with C# client (many posts of me about). There is a reference to simply do this or a tool ?

thanks you two Lor*
