Thanks Ramesh S, This solved the problem. But i have few more questions in mind. While adding assemblies to the web.config file we have to sepcify the name of the assembly,version, culture and public key token. I found the public key token for the assembly as you have suggested. Is it possible to find the version and culture of the assembly.
1. Open the folder , where you placed you assembly .dll, using Windows Explorer.
2. Just right click on the assembly .dll file
3. Go to Versions Tab
4. Click on the File Version item in the Other version informtion panel to see the version details
5. Click on the Language item in the Other version informtion panel to see the version details
Mark as solved if this post answered your question
