I downloaded the source from that link, but it doesn't appear to build properly. Is there a problem with the source?

It appears to be working fine on my end. I'm testing with VS2008 SP1 and SQL Express 2008. What error are you getting?

Does the webmail demo work with visual studio 2008? When I try to build the website I get the following error:
Error 1 Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. C:\Documents and Settings\jay\Desktop\source\Web.config 17
I understand that .Net 4.0 does not work with vs 2008. Is there a version of the webmail demo that works with vs 2008 and .Net 3.5?
thanks,
Jay
The latest online version of our WebMail demo is built against .NET 4. If you want to use it under VS 2008 and .NET 3.5, you will need to modify the application's web.config to include references to the .NET 3.5 versions of the assemblies registered there.

i was getting the this error when i opened the demo on VS 2008 and Sql server 2008
Error 1 Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive. C:\Documents and Settings\jay\Desktop\source\Web.config 17
Then i changed web.config to framework 3.5 & after changing into web.config i m getting this error
Error 48 Could not load file or assembly 'Telerik.Web.Design' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
will you please suggest me how can i check the demo on Vs 2008 as i don't have vs 2010.
Did you also replace the Telerik assemblies in the bin with their .net 3.5 build version?

I'm new to telerik, i have downloaded the demo version of telerik. i'm using microsoft visual studio '05 and framework of 2.0. When i try to open "RadControls for Silverlight Q2 2012 Demos" i'm getting this "Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive" error in my browser. even i have tried changing the framework in this path"C:\Program Files\Telerik\RadControls for Silverlight Q2 2012\Demos\Examples.Web" but still its not working. Any help will help me alot.
You need to run the sample in .NET 4.0. Here are the requirements taken from the readme file of the webmail demo:
==== Requirements ====
Telerik RadControls for ASP.NET AJAX Q2 2012 (2012.2.607, full trial or purchased installation)
Visual Studio 2010 (or later)
Microsoft .NET framework 4.0
SQL Server Express Edition 2008 (or later)
==== Connecting to a different instance of SQL Server ====
The application is configured to connect to the (local) instance by default.
If your SQL Server is using a different instance name, update the connection string in the web.config file.
