Recently, in a project upgrade task I faced an issue on Team City, the code was perfectly building on my local but failing on Team City
error CS0012: The type ‘System.IDisposable’ is defined in an assembly that is not referenced. You must add a reference to assembly ‘System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’.
Conditions:
- Microsoft .NET Framework 4.5.2
- Unity Project
After some attempts, nothing solved, the solution was the installation of “Microsoft .NET Framework 4.5.2 Developer Pack” on Team City servers

Note: If the installation occurs on a Windows 2008, the machine needs to be rebooted, but If the installation occurs in a Windows 2012, the reboot is not necessary. I would like to thank Vinicius Deschamps for this note
