Hi zipzap,
The fact that we still do not have an example/help topic for CRUD with ASP .NET does not mean that it is not supported. Our product is a JavaScript library + HTML so it should be relatively easy to build CRUD with ASP .NET, but we still do not have the sample. We try to provide create more and more samples and to improve our documentation with every new version. However, we still did not cover all scenarios for the most popular technologies. We will do our best to provide CRUD with ASP .NET sample in a future version. In order to use the widgets in .NET, MVC3 or MVC4 is not something that is required.
