Autotagging and versioning for C# app with AppVeyor and Git

I needed a way to auto-tag my release when I’m modifying the AssemblyInfo.cs file in my C# application.

I created a pre-commit, post-commit and simple file to do so:

The contain which file need to be monitored. When this file is changed and part of the commit, the new version will be extracted. (please be sure you only have one

[assembly: AssemblyVersion("3.4.2.*")]

in your Assembly file). The version need to be specified as shown (X.X.X.X) where the last X is the build version (that I let Visual Studio manage and don’t consider relevant for a tag).


Check for version change, if it’s the case, change also the version the appveyor.yml file and add it to the commit.


If the version change, add a new tag using the commit message and the version extracted from the AssemblyInfo.cs file.
