SysThough I am not very sure, but we had a similar problem in our project. If we choose the framewrok to 4.0 (the project was supposed to run in 3.5), we used to get these errors. To resolve it go to your web.config file and change the 4.0.0.0 to 2.0.0.0. It worked for us! Hope it helps :)

Hi, Where in the Web config we have to change the version from 4.0.0.0 to 2.0.0.0, I am not seeing any where that I am setting it to 4.0.0.0. Can you please point me the element name in the Web config I have to do it? Thanks in advance.

SysThis is the same problem I had two days ago and it took me way too long to figure out. If you right click the project in Visual Studio and go to Property Pages you will see the targeted framework. You have said that your's is targeted correctly however under MSBuild Options make sure that you do not have any of the checkboxes checked. It took me forever to figure out that I had one checked off and it was interfering with testing in the browser. Hope this helps.
