webservice

Hi,

Hi,

I have an application which has three layers

1. ASP.Net application (C#)
2. C++ Manged
3. C++ Native

C++ Native has all the intellegnce and algorithm, and C++ Managed is wrapper, so it should be easily work with C# code. My application is working well when we are working on desktop. Now we want to expose C++ Managed code (which is wraper for C++ Native) as web service. It works fine till it goes throuh .Net code, but as soon as native code started executing web service stopped working.

Which tool I should use? How should I expose my unmanaged C++ code?

Thanks in advance.
