Getting the ExecutingAssembly Location / SecurityException

Hi, I've added a reference to a class library assembly in my Office Project.

If I do :

System.Reflection.Assembly.GetExecutingAssembly().Location

from my Office application, it works fine. However, if I put the same code in my class library, I get a SecurityException when accessing the Location property when it's called from the Office application.

The goal of the class library is to offer some tools I can use from various .NET projects. In this particular case, I need to know the location of my Office application DLL and use it internally. Passing the path from the application isn't an option.

Does anyone have any idea how to fix this problem?

PS: I use Visual Studio 2005 Beta 1

Thanks, Martin

Any additional assebmly called from VSTO solution requires a separate FullTrust to execute. Use caspol.exe to trust your library at either user or machine level. For example:

caspol -u -ag All_Code -url file://YourAssemblyName.dll FullTrust

Right ... to access that property you'll need to have PathDiscoveryPermission. If you want to only add one code group to your policy, instead of using a UrlMembershipCondition like above, you could strongly name your assemblies using the same key and then trust that single key. I give instructions for how to do that here: http://blogs.msdn.com/shawnfa/archive/2005/04/14/408284.aspx
