I included a link to a SharePoint Solution Template for VS.Net 2005 in my previous post, which I discovered was a broken link, so I have created my own and you can get it here.
It is VERY basic. Just one of our deployment solutions stripped of all the content, which the makecab/build targets setup and the directory structure for things like assemblies, templates and the folders for each file destination.
One day I'd like to automate the generation of the DDF file, perhaps via a macro or XSLT.
The Project Template will appear under My Templates in the C# area (assuming you put it in the top level templates area under the Visual Studio 2005 directory in your My Documents area).
It will prompt you with a warning about possible badness because of the custom build target stuff, but ignore and open normally - unless you don't trust me of course ;-)
