I had still this Problem (.NET 4.5). I my case the problem was, that the computer was not connected to the internet, but there were some other device (cameras etc.) which were connected via GigE. The startup of every .NET Application was delayed for about 20 seconds.

The solution was quite easy: Just connected the computer once to the internet, started any .NET application (first startup took about 7 seconds) and after that, every startup was quite fast, even if the computer was no longer connected to the internet. In addition I had to disable the protocol TCP/IP V6 (caused 3-5 seconds delay).

Another possible solution is to select Properties for the "internet Protocol Version 4 (TCP/IPv4), then select Advanced, select the tab "WINS" and set "Disable NetBIOS over TCP/IP".
