Application identity not set Exception

问题

I have just converted a project to VS2010 and I now starting to see Exceptions in my software in IntelliTrace.

One such Exception is 'Application identity is not set', this occurs whenever my software see's something like

string m_AppPath = Application.UserAppDataPath;

This isn't a problem as the AppDataPath returns correctly, I'm just wondering why this happens.

The code is in the Main function of Program.cs (if that makes a difference), once out of the Program.cs file and into MainWindow.cs the code works.

My main issue is that I setup Logging prior to the application starting. Any help appreciated as searching the web doesn't really help.

If the problem is occuring in debugging you can first check if the debugger is attached before accessing any application settings:

If System.Diagnostics.Debugger.IsAttached then
       Me.Text = "Debug Mode"
Else 
       Me.Text = "Version " & My.Application.Deployment.CurrentVersion.ToString
End If

I found that this problem exists only if you untick "Just My Code" under debug options.

If this is a ClickOnce application being debugged, another option is to check the System.Deployment.Application.ApplicationDeployment.IsNetworkDeployed setting.
