Opening the Network Atlas fails. In the Network Atlas log file, you can find the following error: 

[1] FATAL NetworkAtlas - 
Message: Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly 'mscorlib, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.


  • Network Atlas on a server with .Net version earlier than .Net 4.5


Upgrade the .Net on the server with Network Atlas to version 4.5 or later.
