I have .net 3.5 program where i load some assemblies from a network share via reflection. Now i've got the following exception: "That assembly does not allow partially trusted callers''(Detailed message below).

The calling assembly(.exe) is local. This .exe loads the assembly from network via reflection. The assembly from the network share then has a reference on a third assembly which is located beneath the .exe. (Hard to explain, image will do better...)

The reason for this failure is the .net security. It doesn't allow the MyLib.dll to be loaded, because the calling assembly is located on a network share and is signed with a strong name.

Solution 1, caspol.exe

Allow all code to be executed.

This might be dangerous, but if you're desperate it could be a solution.

 "C:\Windows\Microsoft.NET\Framework\v2.0.50727\CasPol.exe" -machine -chggroup All_Code FullTrust

Solution 2, no signing

If you remove the signature from MyLib2.dll, everything works.

Solution 3, set attribute AllowPartiallyTrustedCallers

If you set the AllowPartiallyTrustedCallers in the AssemblyInfo.cs of the signed assembly, everything works.

using System.Security;

[assembly: AllowPartiallyTrustedCallers()]

If you debug your windows phone application, and the OnOrientationChanged event is not fired, just press Page Up or Page Down. Those keys are used to activate/deactivate the phone keyboard. If the phone keyboard is active, the following code will be executed. Strange thing...

protected override void OnOrientationChanged(OrientationChangedEventArgs e)
{ 
   base.OnOrientationChanged(e);
}

Found(after some time) on the microsoft forum.

This is the list of issues/features i have in mind. I'm not sure whether i will solve all of those, or even when. It's just to keep them in mind. Write me a comment if you have anything in mind which should be changed/fixed.
