If you installed IIS after installing dot net framework,then you wont be able to debug the project in visual studio…

Reason
The IIS is not configured with asp.net .Simply IIS dont know what is asp.net..SO we will have to link IIS with our dotnet framework.

Solutions

First Solution

1.Take start >Run
2.Copy the code below and press Ok

“H:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe” -i

Replace ‘H’ with the drive in which your windows is installed.
Replace v1.1.4322 with the version of your dotnet framework

Trouble shooting —>If this is not working the take search and search for the file aspnet_regiis.exe ….If found copy its address,compare it with the code above and rewrite the code…DOnt forget to write ‘-i’ at the end

Second Solution

If you dont understand the first solution then simply reinstall dotnet frame work

It will be in the Visual Studio Prerequisite CD….No need to reinstall entire Visual Studio
