Usage

1. Put Directory.Build.props in your project props directory or your project root directory

Setup

1. Create empty file .reporoot in your project root directory
2. Adjust <SrcRoot> nicely

Option

If you want to use 7-chars hash instead of full hash, use this diff.

-        <VersionSuffix Condition="'$(GitHeadSha)' != ''">git-$(GitHeadSha)</VersionSuffix>
+        <VersionSuffix Condition="'$(GitHeadSha)' != ''">git-$(GitHeadSha.Substring(0, 7))</VersionSuffix>
