Set-AssemblyVersion.ps1

<#
.Synopsis
   Sets the assembly version of all assemblies in the source directory.
.DESCRIPTION
   A build script that can be included in TFS 2015 or Visual Studio Online (VSO) vNevt builds that update the version of all assemblies in a workspace.
   It uses the name of the build to extract the version number and updates all AssemblyInfo.cs files to use the new version.
