Xamarin iOS: message to build client ... canceled

Question

I can not start the Xamarin application from visual studio on my PC in iOS Simulator on a network Mac.

I get the following error:

C: \ Program Files (x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS.Common.targets (543.3): warning: message to the build7148techn client on xvs / Build / 4.2.0.680 / execute- task / RFTIOS / 5434a49% 2FDetectSdkLocations canceled 1> C: \ Program Files (x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS.Common.targets (543.3): warning: operation was canceled. 1> C: \ Program Files (x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS.Common.targets (543.3): warning: in System.Threading.CancellationToken.ThrowOperationCanceledException () 1> C: \ Program Files ( x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS.Common.targets (543.3): warning: when System.Threading.CancellationToken.ThrowIfCancellationRequested () 1> C: \ Program Files (x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS.Common.targets (543.3): warning: on Xamarin.Messaging.Client.MessagingClient.d__23`2.MoveNext () in C:\ data \ lanes \ 3513 \ c4382f51 \ source \ xamarinvs \ src \ Messaging \ Xamarin.Messaging.Client \ MessagingClient.cs: line 135 1> C: \ Program Files (x86) \ MSBuild \ Xamarin \ iOS \ Xamarin.iOS. Common.targets (543.3): error: message for client build7148techn on xvs / Build / 4.2.0.680 / execute-task / RFTIOS / 5434a49% 2FDetectSdkLocations canceled

Does anyone know how I can solve this error?

Answer 1

Your "question" is not very descriptive, but, nevertheless, Google made me here. Today I have the same error. This is what worked for me (not sure if all steps are needed to fix the problem)

• Restart MAC
• Reboot the computer.
• Delete bin and obj folder in project folder
• Clear project (in Visual Studio)
• Rebuild

Answer 2

@boulev and tie: today I had the same problem and I can confirm that you need to restart Visual Studio. Enough.
