Edit: Oh, I really havenβt seen that you are going to create a new project type for C ++ Builder files. In this case, you need to create a language pack. Visual Studio Extensibility site should get started. Also see this more specific link .
I will leave my old answer here for reference, because it can help people who just want to create C ++ Builder projects without creating a completely new type of project :)
You did not specify a version of Visual Studio, but I assume a recent one. In Visual Studio 8 and 9, most project files (all popular except Visual C ++) are actually MSBuild files and therefore can be created by MSBuild. You can add a simple command line task (Exec) to create your bpr in the command line or create a custom task for it (if you do not find it already available, the search conditions must be MSBuild and a custom task), thus, Visual Studio and MSBuild can create whatever you like. If you donβt have an MSBuild file to start with or want to dive into the task development,
