@sam - You can't install ASP.NET - you can install IIS or .NET framework. so which of those is it? Also, did you follow the exact steps described here? technet.microsoft.com/en-us/library/cc731911.aspx –  Shadow Wizard Nov 23 '10 at 13:05

this might help somebody else... I just spent 10 minutes trying to figure out this same issue.

Check if your project is actually marked for Build in Configuration Manager. For some reason my MVC4 project was not checked.

You might wanna register asp.net with iis. So install iis using the features and then execute the command "aspnet_regiis.exe -i" with the Visual Studio Command Prompt.

ok i did that and it says aspnet_regiis.exe -i is not recognised as and internal or external sommand operable program or batch file??? –  sam Nov 23 '10 at 12:56
    
Try navigating to the folder "C:\Windows\Microsoft.NET\Framework\v4.0.30319" with the VS Command Prompt. It's located in that folder. –  Fabian Nov 23 '10 at 13:28
    
says the samething as before –  sam Nov 23 '10 at 13:31

Check the System Event log for ASP.NET and related events. Then you can confidently search the web for information on the relevant errors you find.

Also, the path to the ASP.NET 4.0 IIS tool is:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i

Another method is to browse to the v4.0.30319 directory and find the file. If you can find it, hold down the shift key and right-click aspnet_regiis.exe. Choose copy as path, then paste into the command prompt with the -i flag. If it isn't in the directory, you have other problems. ;)
