AppActivate In C#

AppActivate, which many of you may recognize from VB activates a window for an application which is already running, bringing the window of that app to the foreground.

In C#, there is no exact equivalent to this function, which leaves two alternatives (see link at the bottom for code examples):

Option 1 (recommended):
Use SetForeGroundWindow, described in my similar post (scroll down a bit for the code examples).

Option 2:
Add a reference to Microsoft.VisualBasic and call Interactive.AppActivate.

Although Option 2 is a little simpler/faster if you are not familiar with or ready yet to delve into Win32 API, it is not a recommended solution as there can be potential side effects of this approach.

For code examples of both options, see my similarly titled post below and scroll through for code references.
