By clicking on a certain command in my code, I get the information not available and available within my project. I do not understand how this is possible, and informs me that you can use the navigation bar to switch context, but I do not know how to do that. The attached figure shows the message. My questions are:

  1. How can something be available and not avilable in the same project?

  2. What is the navigation bar and how do I use it to change the context?

This is the message I received:

Usage:
  Dim r as list (of Streaming) = Await StartAsync(...)
   MSGEM – Available
   MSGEM – Not Available
You can use the navigation bar to wsitch context.

This could be be down to two front-end files sharing the same back-end codefile. In such a situation, the code file will reference a front end control which is in only one of the front end files and not both.

If you do not use such a coding technique, it can easily happen accidently when making a backup of a front end code file by copying it to a different filename but forgetting to add the .exclude extension.
