Framework of the ASP.NET

I am having a problem with my computer program.  I do not know what the Framework is for this program.  Can you help me?  

This is the configuration error in the web.configuration file.

<compilation debug="true" strict="false" explicit="true" targetFramework="4.0">

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I assume that you'll need the framework .NET 4.0
If you're using Visual Studio 2010 try right-clicking on your web site/web appication in solution explorer and go to properties.

Go to Build and check that target framework is set to ".NET Framework 4" then OK.

If you're working with .net 4 (or want to) you're probably best off installing the 2010 version of visual web developer express -
