Using Web.config transformations in Sitefinity v. 4.x

In Sitefinity v. 4.x, the connectionStrings element has been moved from the Web.config file to a file called DataConfig.config.  Unfortunately, the move away from the Web.config file does not allow one to leverage Web.config transformations which were introduced as part of Visual Studio 2010.

Fortunately, the folks at Telerik are able to offer a solution that will allow developers to continue to utilize Web.config transformations:
