Hi!

Is creating a new Project type really the only way if you want to
participate in the build process like I want to do?

I have an own file type and my build tool builds a number of source
files. Those source files (e.g. C# classes) should be referenced and
compiled in the VS project. I have already an editor for this file type
as a VsPackage and the package could also do the build step.

Adding a Custom build step is not convenient for the user and is also
restricted to a command line interface.

Typically the user (developer) would add the build parameters for my
file type as properties. During the build process I would like to get
an event whenever my file has to be processed.

Any ideas? Thank you in advance! Regards :-)
