I just ran into a little problem when attempting to run a Visual Studio unit test on my Windows 7 machine. I downloaded log4net.dll and wanted to use it in a project, but when running the unit test I ran into the following error:
Failed to queue test run 'Mark@L-ONE 2009-10-11 14:08:38': Test Run deployment issue: The location of the file or directory 'c:\users\mark\documents\visual studio 2008\projects\sources\developone.myproject.unittests\bin\debug\log4net.dll' is not trusted.
Turns out that a downloaded file is blocked. You can unblock the file by right clicking the file and choosing “Unblock”.
Make sure you remove all copies of the assembly (if you have copy local = true) and then recompile.
