This adds support for F# project files which are the same xml format as those of C# & VB.Net. It also adds support for props files which are used to extend them. MSBuild assumes a file name of Directory.Build.props but you can also manually import files of any name which commonly use the .props extension.

Sample F# project file
https://github.com/cartermp/GiraffeSample/blob/bbb8a0d3d08a31bf8d9ecac75457cd41953e8414/LunchAPI/LunchApi.fsproj
