Q3 2010 SP 1 has been a pretty bountiful release for the Telerik Extensions for ASP.NET MVC. Apart from introducing the official support for MVC3 and the Razor view engine, this Service Pack also makes the Extensions available in the NuGet package manager. You can now incorporate the Telerik Extensions for ASP.NET MVC into your app during development without having to leave Visual Studio.
Talking about Razor, you can now find all Telerik MVC examples in both ASPX and Razor views. What is more, you might be interested to take a look at the open source Razor Converter tool which the Telerik ASP.NET MVC team created first for internal use, but then decided to share on GitHub hoping the community will develop the tool further. This simple tool converts ASP.NET MVC WebForms Views to the new Razor syntax. Of course, it has its limitations, since completely automatic conversion is hardly possible, but it can do the dirty work for you.
