Build fails due to postsharp error: Pipe server exited prematurely with exit code 1

Question

i am unable to build projects and solutions when postsharp is part of the project. even when postharp is not used but only installed as nuget, the build fails.

when building, i get the following behaviour: build stalls and opens multiple postsharp-x64-srv.exe processes that use 100% of the cpu. when i manually stop the processes, i get following errors:

• pipe server exited prematuraly with exit code 1.
• PostSharp.targets(333,5): warning : The server shut down while waiting for PipeAvailableEvent.

it appears that the proxy enviornment from work is the issue (see below for description)

background

• i use visual studio 2017 on windows 10.
• i work behind a proxy that requires authentication
• postsharp version is 6.0.27

already tried

• already set the host to native => no luck
• disabled the pipeserver => no luck
• already tried the latest version (6.0.33) and has the same result.

what does work (but is not acceptable behaviour i think)

• building on home computer (so without the proxy environment from work)
• building with all networkadapters disabled on work computer

please advise on how this can be resolved
