I'm a .NET developer and want to write an IOS & Android app in C#. I've had a read around Xamarin for Visual Studio which looks interesting if not a tad expensive!
Do you need a Mac to debug your code? Do you just need a networked Mac to actually deploy the app to the Store?
Is the best option just to buy a Mac and run Windows with VS in a VM or can I just use my windows machine, write & debug the code in Windows then just hook up to a networked Mac for final deployment?
From May 2017, you can develop app without MAC.
Microsoft Xamarin introduce a Live Player. With Live Player, iOS apps can be deployed directly onto an iPhone or other iDevice from a PC running Visual Studio, where the code can then be tested and debugged.
