	// Instructions
	// 1.  Add a new Text Template to the project
	// 2.  Copy this file into the new template
	// 3.  Update the string: versionfile with the complete path to the .version file
	// 4.  Remove the following line from the file AssemblyInfo.cs (usually located in the "Property" folder inside your C# project):
	//        [assembly: AssemblyVersion("1.0.0.0")]
	// 5.  Add the following to the PreBuild steps:
	//
	// set textTemplatingPath="%ProgramFiles(x86)%\Microsoft Visual Studio\2017\Community\Common7\IDE\texttransform.exe"
	// %textTemplatingPath% "$(ProjectDir)AssemblyVersion.tt"
