It's not the languages, it's Visual Studio that provides the extensibility. First step: Understand that with VFP, the language and the IDE are inseperably linked together. That's not the case with Visual Studio and the .NET languages. You have different parts that are used together, but not insperably linked. You can develop C# or VB apps without VS. You can also create your own language and hook it into VS. One problem that you're going to run into is that Microsoft keeps changing how add-ins to VS work. DevExpress created DXCore, that is supposed to make it easier to write VS plug-ins. Start by looking at that.

>Hi,
>Do the .NET languages have the ability to create builders like in VFP? I create the tools the other developers in my shop use and they are used to builders that greatly speed development. Things like a form builder that allows fields to be dropped on a form and the framework knows how to get data to and from various SQL Server databases, that sort of stuff.
