Can't enter break mode at this time

Break mode is the state in which a program is still running, but its activity is suspended. This error has the following cause and solution:

• You tried to enter break mode, for example, by pressing CTRL+BREAK, pressing the Break button on the Standard toolbar or the Debug toolbar, or by executing a breakpoint in the running code.

  A change was made programmatically to the project using the extensibility (add-in) object model. This prevents the program from having execution suspended. You can continue running, or end execution, but can't suspend execution.
