Detect local application path

How do I detect my local application path?

When launched from a Web server .NET applications are copied in the assembly download cache (ADC) of the client machine.

Note: Please be aware that you have no right to read or write within that location by default and need to assign the necessary permissions or FullTrust to the assembly.

When you write a Windows Forms application there are basically four ways how to determine your application path.

• Application.ExecutablePath (Windows.Forms)
• Assembly.CodeBase (Reflection)
• AppDomain.CurrentDomain.BaseDirectory (System)

These three return the URL to the folder on the web server the application was launched from. And finally...

• Assembly.Location (Reflection)

... returns the local path in the assembly download cache (assuming the necessary permissions).
