I was recently writing a server status report program to check the statuses of servers and produces a text file report (stunning good naming scheme I know) and I ran into an error that was quite perplexing mostly because it shouldn't have been happening for various apparent reasons. On launch of a unit test, I received the error ---- Could not load file or assembly 'file:///binDebugsome.dll' or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) ---- This is quite the problem since unit testing is a wonderful thing sent down from God Himself to bless us developers (who ever said God wasn't good?). **The problem here is that Visual Studio won't load in untrusted assemblies**, and assemblies on a networked drive are not considered trusted, *. That being said, to fix this problem, all we need to do is allow remote sources to be loaded in. Here's how... Open up **C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config**. Near the top of the configuration file (mine was line 10) you should see an xml parent of ****. Directly beneath that add ** image:files/devenvConfig.jpg[height=300] Save and close out *devenv.exe.config* and restart visual studio. On restart, you should now be able to debug using assemblies in remote locations. Category:Microsoft Category:Visual_Studio // vim: set syntax=asciidoc:
