Keeping Visual Studio Projects on a Network Drive

In the interests of actually answering the question, I copied this comment from jcarle.com:

Trusting Network Shares with Visual Studio 2010 / .NET Framework v4.0

January 20, 2011, 4:10 pm If you are like me and you store all your code on a server, you will have likely learned about trusting a network share using CasPol.exe. However, when moving from Visual Studio 2008 (.NET Framework 2.0/3.0/3.5) over to Visual Studio 2010 (.NET Framework 4.0), you may find yourself scratching your head.

If you are used to using the Visual Studio Command Prompt to quickly get to CasPol, you may find that some of your projects will not seem to respect your new FullTrust settings. The reason is that, unless you are carefully paying attention, the Visual Studio Command Prompt defaults to adding the .NET Framework 4.0 folder to its path. If your project is still running under .NET Framework 2.0/3.0/3.5, it will require setting CasPol for those versions as well. Just a note, I have also personally had more success with using 1 as a code group instead of 1.2.

To trust a network share for all versions of the .NET Framework, simply call CasPol for each version using the full path as below:

C:\Windows\Microsoft.NET\Framework\v2.0.50727\CasPol -m -ag 1 -url file://YourSharePath* FullTrust
C:\Windows\Microsoft.NET\Framework\v4.0.30319\CasPol -m -ag 1 -url file://YourSharePath* FullTrust

While we do use Source Control, we do also run all our projects from Network Drives (not shared directories, private directories on network drives). The network drives are backed up nightly, and also use Volume Shadow Copy, so if you need to revert to something before it made it's way to SC, then you can.

To get projects to run correctly with the right permission, follow these steps.

Basically, you've just got to map the shared directory to a drive, and then grant permission, based on that Url, to all code. Say you map to "N:\", then use "N:\*" as your Url pattern. It isn't obvious you need to wildcard, but you do.

The question is rather generic so I'll give an answer to one issue I was facing.

I run Visual Studio 2010 using a Parallels virtual machine on my Mac while keeping all my projects on the mac side via a network share. Visual Studio however wouldn't load the projects assembly files from there. Trying to set the rights using "caspol" alone didn't help in my case.

What finally worked for me to allow Visual Studio to load assemblies from a network share was to edit the file "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe.config" (assuming a default installation).

in the xml "<runtime>" section you have to add

<loadFromRemoteSources enabled="true"/>

You may have to change the permissions on that file to allow write access. Save the file. Restart Visual Studio.
