Error: Unable to start debugging on the web server.

 

If you are getting an error like the following

“Unable to start debugging on the web server. See help for common configuration errors. Running the web page outside of the debugger may provide further information. Make sure the server is operating correctly. Verify there are no syntax errors in the web.config by doing a debug.Start without debugging. You may also want to refer to the ASP.NET and ATL Server debugging topics in the online documentation.”

Make sure you look into your event log. That may provide you with extra information that might be crucial to the resolution of the issue.

Make sure that you grant the user created in step 2 the permissions to access files and folders. I on my development box generally make it an administrator and give it full control on files and folders.

Also make sure you are changing the configuration files of the same version which that project uses to run. E,g, if project is .Net 3.5 then modifying the configuration files of .Net Framework 4.0 will not have any effect.

Hope this helps.
