I'm a beginner in ArcGIS & I'm shooting blind really. I want to add the Network Analyst tool box to find the shortest path in my project. I tried this solution:

I can't add Network Analyst dll to my web mapping application. I use ArcGIS 10 & Visual Studio 10 and I used web application adf to build my website. I tried the Network Analyst toolbox or networkanalyst.dll from developer kit folder but an error occurs:

The dll not found.

Any help will be appreciated.
