This feature allows you to step into the member at the caret when debugging. Just place the caret on the member you want to drill into, and press CTRL+SHIFT+F11, or click the Step Into Member button on the Debug toolbar.
Program execution will jump to the first statement inside the method or property at the caret.
For Step into Member to work, source code to the method or property at the caret must be part of the active solution.
Step into Member is useful when you encounter code like this while debugging:
Text = blackBox.Encode(GetFullName(FirstName, MiddleName, LastName));
If you want to step into blackBox.Encode without stepping into the property getters for FirstName, MiddleName, and LastName, and without stepping into the GetFullName function, just place the caret on the "Encode" member on the line, and press CTRL+SHIFT+F11.
