Walletwasabi: AsyncMutex: NotImplementedException

[lontivero]

General Description

After killing the Wasabi process and restart it I got the following error message:

ERROR AsyncMutex: NotImplementedException: The method or operation is not implemented

The problem is that I cannot open the wallet any more (i think I will need to restart the laptop because it shows me the same error message again and again.

How To Reproduce?

1. cd WalletWasabi.Gui
2. dotnet run
3. open a wallet (I am not 100% sure I did this step)
4. close wasabi with the cross button on the top right corner
5. kill wasabi with CTRL+C (because it didn't finished)
6. I got the error. If you don't get the same error go to step 1.

We throw one NotImplementedException, but we don't have Message there. It seems to me that .NET Core is throwing it, that it's on Linux something is not implemented that we are using. @molnard can you take look at it? I added a priority label to this issue. (Even more priority than the rest.)

@lontivero since you can reproduce it, can you somehow figure out where the exception is thrown?

Could reproduce the error on my Ubuntu. Move forward to debug it.

@lontivero I have an idea could you verify if it solves anything?

@molnard the NotImplementeException is not raising any more ;) However there is another behaviour that I am not 100% sure is new but could be. Now, when I kill an instance, the services stop okay and the log says the Wasabi was stopped but the GUI is still there in my screen, it doesn't do anything but I have to kill the process by command line.

These two instances where killed but they survived someway.

I will try to reproduce it with 1.1.4 but I don't remember this problem.
