ASP.NET IIS Registration Tool – Aspnet_regiis.exe

When multiple versions of the .NET Framework are executing side-by-side on a single computer, the ASP.NET ISAPI version mapped to an ASP.NET application determines which version of the common language runtime (CLR) is used for the application. The ASP.NET IIS Registration Tool (Aspnet_regiis.exe) allows an administrator or installation program to easily update the script maps for an ASP.NET application to point to the ASP.NET ISAPI version that is associated with the tool. The tool can also be used to display the status of all installed versions of ASP. NET, register the ASP.NET version that is coupled with the tool, create client-script directories, and perform other configuration operations.

Problem Situation

I have faced one problem while deploying the website.

Actually I need to deploy a website on my computer where all the ASP.Net Framework are installed like 2.0, 3.5 and 4.0

After that I have installed the IIS on computer properly and I have deployed my website

My website is not working because my all the framework are not registered with my IIS Server. This is because my frameworks are installed before the IIS installation that why it is not registered with IIS server

Then I have to registered framework with IIS Server with the help of ASP.NET IIS Registration Tool (Aspnet_regiis.exe)
