When, at some point, for some reason, you would like to create a RAR- or ZIP-file for the source code you created, you can do so in WinRAR, by using the following exclude filter.
Be aware, that this will include any *.btp.cs, *.xsd.cs, etc…
These files should not be part of your TFS/VSTS, but are created by Visual Studio.
You could add them to the filter, creating the following exclusion:
*\bin *\obj *.xsd.cs *.btp.cs
