Use this as a pre-build step, either as part of your TeamCity/TFS/etc process or by adding it to the pre-build step of your project, like the following example. Assuming you have the script saved in a directory build located in the same directory as your .sln file:

<Project> 
  <!-- usual other stuff here //-->
  <!-- ... //-->
  <PropertyGroup>
    <PreBuildEvent>powershell -ExecutionPolicy RemoteSigned -File  $(SolutionDir)build\gitinject.ps1 $(ProjectDir)</PreBuildEvent>
