How to set runtime for .Net application

Question

How to set the execution level for a .Net application to run with administrator privileges when it is launched in a regular user account in Win XP?

Answer 1

access to the registry requires an elevated privilege. However, there is only a piece of code that requires additional permission. Impersonation is used to process such scenarios, that is, you will run this application as a regular user, but this particular piece of code will be executed as if you were an administrator.
