cannot get visual studio connected to mac

I've tried to get Visual Studio 2019 (Community Edition) working with a Mac to create a Mobile app iOS and Android. Unfortunatly I'm struggling the whole day wit this combination.

My current issue, which I cannot solve myself is the following error in Visual Studio on Windows:

An unexpected error occurred while checking the SSH configuration of '192.168.178.74'
An item with the same key has already been added.

I tried to change the MAc Address of the virtual machin to get a new IP Adress, without success

my setup:

Btw. I forgot to mention, that it is possible to log in to the Mac via ssh from Windows.

I had not Monotouch folder, so I created it manually and run VS using Administrator privileges. This solved my problem.

I found this error happened on VS 16.5.2 and after updating to 16.5.3 today it fixed the issue.

It looks like this is an issue with Visual Studio on Windows. Microsoft seems to be aware of this and working on a solution.

Details: https://developercommunity.visualstudio.com/content/problem/928605/an-error-occurred-while-generating-the-ssh-keys-pl.html

Update: Microsoft just recently released version 16.5.2 of Visual Studio. That released (non-preview) version fixed the issue for me ;-)

I was able to get this working. It seems that running chmod og-w "$HOME" on the MacOS device fixed it for me.

However, I'm not 100% sure that was the only step because I've been debugging this for hours, so everything I did might be unnecessary, but if the above doesn't work alone, here is everything I did:

  1. Followed steps from https://github.com/xamarin/xamarin-macios/issues/7882#issuecomment-604330852 to copy old scp (again, don't know if this was necessary)
  2. Restart both machines just so you're sure you have a clean slate.
  3. On the PC, delete contents of %LOCALAPPDATA%\Xamarin\MonoTouch directory (leave the directory itself)
  4. On the Mac, clear contents of ~/.ssh/authorized_keys file
  5. On the Mac, delete ~/Library/Caches/Xamarin/XMA directory
  6. On the Mac, run chmod og-w "$HOME"
  7. On the PC, start Visual Studio and try to connect

My fix to this issue was to delete the hosts.key file in this directory

%LOCALAPPDATA%\Xamarin\MonoTouch
