LiveSharp 1.6.31 crashes iOS app at launch

[michaelstonis]

I updated LiveSharp to 1.6.31 and backed by server 1.6.7 and my iOS app crashes at launch with the following error. The livesharp.dashboard.cs file is using the out of the box configuration.

Transport type: LiveSharp.ServerClient.SocketTransport

Hey @michaelstonis

Did you restart Visual Studio after the update? Also, please make sure to do a full rebuild.

[streinhard]

I have the same issue with all Livesharp Versions higher than 1.6.12. The Crash is exactly the same as @michaelstonis stacktrace. I always did a full rebuild for every version. Seems like there is a bug in CreateInterceptorOnly().

[ionoy]

Hey guys!

This issue should be fixed in the latest release. Please try it out!

After experiencing the described issue on Xamarin iOS I updated the nuget to 1.6.52 and used server to 1.7.2. Crash still happens at iOS LoadApplication(new MyApp.FormsApp()), but with this Stracktrace
