Hot to debug Code actions?

If you want to launch the debugger and use breakpoints, you need to perform a few preparatory steps.

First, you need to run WorkflowServer in your IDE in debug mode. Next, you should enable debugging during the initialization of WorkflowRuntime:

WorkflowRuntime.CodeActionsDebugMode = true;

Or you can set a configuration parameter in the config.json file:

{
  // ...
  "DebugMode": true
  // ...
}

Then, you can set a breakpoint right in the code of CodeAction by writing /*break*/ (commentary brackets do matter).

It is rather convenient because if debugging is disabled, a breakpoint will transform into an ordinary comment. At the same time, if debugging is enabled, a breakpoint will turn into the following code:

if (System.Diagnostics.Debugger.IsAttached) {
    System.Diagnostics.Debugger.Break();
}

That's it! Now, when your Code Actions are executed, the program will stop at your breakpoints in the IDE.
