What do you mean by WCF application. There is nothing called as WCF application, there is always a WCF service and service is always the background activity which runs in the background and no UI.
Can you please clarify your question to get correct answer.
If you just want to active another application through the WCF service, you can use System.Diagnostic.Process.Start("yourapplicationname");
Hope it will be helpful to you.

Please elaborate your question properly, so that we can provide you the best solution.
1) If you want to open another application from a windows form application using C# on button click, try following:
Process newProcess = new Process();
newProcess.StartInfo.FileName = "notepad.exe";\\ You can provide here path of your 2nd application.
newProcess.StartInfo.Arguments = @"C:\Users\ShashikantG\Desktop\Movie.txt";
Now you have two applications opened on your computer.
2) If you want to switch between 2 forms use following:
SecondForm frmSecond = new SecondForm();
Hope it helps.
