Whenever I download Visual Studio 2010 projects from the Internet and open the solution I am always prompted by the following message “Security Warning for [project name]. You should only open projects from a trustworthy source”. The warning makes sense because who knows what the code will do and we all run virus scanners for a good reason.

Its easy enough to suppress the warning for multiple projects in the same solution but next time you open the solution you get prompted with the same security warning.


Fixing this is quite easy, just select the project file in the Windows Explorer, right click and open the files properties and click the Unblock button to tell Windows, and Visual Studio, that you trust the file.


Of course you better be sure that you can trust the source code [:)]
