Switching Xamarin Accounts on Mac and Windows

By -
I had a situation where one of our development Macs already had a Xamarin Indie license installed for iOS development.  We then needed to install a client's Business account onto the Mac but unfortunately Xamarin Studio got confused between the two accounts (it showed the new account name but it still said 'INDIE', when it should have said 'Business'). To do a clean switch over you need to do the following:  First make sure you've logged out of your first account.  And login with your new account.  In Xamarin studio you can do this by selecting Xamarin Studio -> Account from the menu bar. Then delete the entire folder listed below.  Windows %programdata%\MonoTouch\License\ %programdata%\Mono for Android\License\ You may need to startup Visual Studio as an Administrator. Mac ~/Library/MonoTouch ~/Library/MonoAndroid When you start up Xamarin Studio, and build the an app it should reset and pick up the new license and

Xamarin Forms - InitializeComponent does not exist in the current context

I was presented with this error whilst developing with Xamarin Forms For me it was simply down to copy and paste :-O.  I'd created a new Xaml Page, which fully qualified was MyNameSpace.MyPage. I then copied in some Xaml which had a different name in the Xaml x:Class attribute (x:Class="NotMyNameSpace.OrPage"). I then tried to compile with our fixing the x:Class attribute and got the 'InitializeComponent does not exist' error. Once I changed the Xaml to match my actual classname (x:Class="MyNameSpace.MyPage") I was back on track and the error went away. Hope this helps. For more information have a look at  forums.xamarin.com The other reason is that you may have created a Shared Xamarin Forms Project rather than a Xamarin Forms Portable project. From Craig Dunn at Xamarin (taken from  Xamarin Forms Forum ) You cannot use Xaml with the Shared Project template with iOS apps (in Xamarin Studio). It's a weird combination to rem

System.UnauthorizedAccessException error with Visual Studio and Xamarin

By -
When you try and install Mono.Android in Visual Studio for the first time you may find that you're presented with an error similar to the one below: System.UnauthorizedAccessException: Access to the path 'C:\ProgramData\Mono for Android\License' is denied. at Xamarin.Components.Ide.Activation.ActivationService.GetErrorWorkflow(LicenseSyncResult[] results, Boolean ignoreSyncErrors) at Xamarin.Components.Ide.Activation.ActivationService.<GenerateFullWorkflowSequence>d__88.MoveNext() at Xamarin.Components.Ide.Activation.ActivationDialog.DisplayWorkflowStep(ActivationWorkflowStep step) at Xamarin.Components.Ide.Activation.ActivationDialog.<>c__DisplayClass13.<StartSpinnerTaskAndScheduleContinuation>b__12(Task t) If you close down VS and run it again as an Administrator it should sort the issue out. Remember activation of your Xamarin licenses doesn't actually kick off until you run the project for the first time. If you're still having activat
