Hello,

Server Error in '/' Application.

Configuration Error

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive.

Source Error:

I have .Net Framewor 4.0 installed on my machine with Silverlight 4.0
also installed. I have vs 2008 sp1 installed on my machine dont have visual studio 2010 installed.

Hello Paras,

The problem is that the .exe from our installation is running ASP .Net Development server . As I can see from the message your server is targeting older version of .Net Framework and CLR. Maybe you have  targetFramework attribute in the root Web.config file of the development server which is not pointing to .Net 4.

The best thing is to install VS2010 because without it in fact you are not able to use SL4. If you want to stick to VS2008 I advice you to install the SL3 version of our controls as in VS2008 you can create only Silverlight 3 projects. You can get it from here: http://www.telerik.com/account/free-trials/download-trial-file.aspx?fileid=10436&dispkey=True

Let me know if you have further questions.

Best wishes,
