Visual Studio Error: "The debugger cannot relax in this frame." for any exceptions

Question

I used to edit and continue when an exception occurred in Visual Studio 2015 C # projects (WPF, if necessary). I often get simple things like null reference exceptions, and I could quickly fix the problem and continue.

However, lately I have been constantly receiving the following warning message:

"The debugger cannot relax in this frame."

He notes that unwinding is not possible in the following:

• Debugging was started using Just-In-Time debugging. - This is not so, I am debugging by running "Start Debugging" from Visual Studio.
• Now unwinding is taking place - not what I know about, if for some reason this does not always happen!
• A System.StackOverflowException or System.Threading.TreadAbortException - this occurs in all exceptions, including simple ones like Null Reference

There are several articles in my googling which say that they implemented this function in 2006, besides this, only about 3 results are returned!

This seems to be a specific project. In a new new project:

Object o = null; String s = o.ToString(); 

Throws an exception and allows me to edit and continue the line earlier. In my existing project, I can’t relax, and it causes a dialogue.

Edit: Tried it using another computer and installing Visual Studio and still has the problem.

There seems to be a problem with Caliburn Micro.

If I have a button on my user interface associated with an event in the code with the above code, I can rewind and debug it. However, if I use cal.message.attach and put the code in the ViewModel reference method, I cannot relax. But I'm not sure.

You can try and test these solutions one at a time. 1. Exceptions are unreliable in optimized code. Enabling "Tools → Options → Debugging →" Only my code "2. Tools | Options | Debugger | General and proven compatibility management mode 3.Under Debug → Options, disable" Enable property evaluation and other implicit function calls. "If this does not work , 4.under Debug → Options check "Use deprecated C # and VB expression evaluators 5. Debug-> Window-> Exclusion Parameters, and then expand the drop-down menu Exception of common languages. Make sure your exception is checked.
