Launching the "Coded UI Test Builder" without creating a new Coded UI Test

With a class like this one, right clicking inside the test method should give you a "Generate Code for Coded UI Test" -> "Use Coded UI Test Builder" option. It will still minimize Visual Studio, but it shouldn't create a new test method. There is also a keyboard shortcut: CTRL+\, CTRL+C

[CodedUITest]
public class MyUITests
{
    public MyUITests()
    {
    }

    [TestMethod]
    public void StartMyTest()
    {
        //right click in here to get the context menu option
    }
}

1. You can open Visual Studio command prompt
2. execute "codedUITestBuilder.exe /standalone"

You can also right click the UIMap.uitest file in Solution Explorer and select "Edit with Coded UI Test Builder" No need for a Coded UI Test this way
