Add the following to your manifest file:
<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
You can also use highestAvailable
for the level.
Look here about embedding manifest files:

PS: If you don’t have a manifest file, you can easily add a new one:
In Visual Studio, right click project -> Add Item -> Choose
Application Manifest File ( under General for Visual C# items)
The added file will already have the above part, just change the level to requireAdministrator
from asInvoker
