Switching Xamarin Accounts on Mac and Windows

By Steve Gray - November 06, 2013

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

By Steve Gray - August 21, 2014

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

How to setup Azure Service Bus Relay to use with ACS

By Steve Gray - September 30, 2015

In August 2014 Microsoft decided to remove Microsoft Azure Active Directory Access Control (also known as Access Control Service or ACS) from the default Azure Portal setup when creating a new Service Bus Namespace. Shared Access Signature (SAS) is now default. Service Bus authentication through ACS is managed through a companion “-sb” ACS namespace and to create this we now need to do it from the Azure Power Shell command line (thanks Microsoft!) To do this: Download the PowerShell console https://azure.microsoft.com/en-gb/documentation/articles/powershell-install-configure/#Install Open up the Console and type Add-AzureAccount and then type in the email address and password associated with your account (Work or Microsoft) Once authenticated you need to create the Service Bus Namespace so it's good to go for ACS. To do this you use the New-AzureSBNamespace command Parameter Set: Default New-AzureSBNamespace [-Name] <String> [[-Location] <String&g
