windows Registry Editor => Computer\HKEY_CURRENT_USER\Software\Xamarin\VisualStudio\MacAgent Just Add new String var "DisableMonoValidation" = "True" Now You can connect but may you can't debug your app

Thanks @Kremed! But I'd rather wait for the effective problem to get fixed...

Thank you for the response! Could you clarify what the "effective problem" is? Are there any resources or updates you could share regarding this issue?

marco-skizza commented 1 month ago

As I understand, there's a problem with a Xamarin website that gets queried by Visual Studio. I think I read in an earlier issue, that this website is hosted by the .NET MAUI team. My point was, that I'd rather wait for the website to be fixed - as I don't want to "mess" with the Registry.

mrdhockey87 commented 1 month ago

I have the same problem and the while the registry entry of "DisableMonoValidation = true" does allow the mac to pair to my Windows system it is useless as I can't access the iOS Simulators or the iPad that I have attached to my Mac. So while it says it's connected it is not really connected as it wont let me do anything that requires a connection to the Mac. Please fix this very Quickly.

We are experiencing the same issue.

LeoJHarris commented 1 month ago

@marco-skizza we updated the registry and its working fine now, removing the the registry key should be as simple as adding it.

The registry only lets us connect, you cannot debug or access simulators, it's not really a 'fix' it just kicks the issue further down the road. Being connected to the mac by itself is useless for 99% of the people who are trying to pair to mac. People shouldn't need to arbitrarily manage registry keys whenever Microsoft drop the ball.

@EddyCwdry Debugger wasn't being impacted for me when adding the registry, maybe check debugger setting if this was changed in the project?

There are no remote devices or simulators listed, can't exactly debug when we can't even pick a device to debug. If you re-read the message by the person saying to add the registry key, they also state that debugging may not work.

Just Add new String var "DisableMonoValidation" = "True" Now You can connect but may you can't debug your app

Some unknown hero fixed the website. Thanks! 👍 If anybody knows (for the next time): Who's responsible for hosting this Xamarin website...?
