There is no way I can list everything I learned with MonoTouch over the last couple of months. I'll summarize my experience by saying I'm a very happy customer. There were bumps and bruises along the way, but between the mailing list and the support crew at Xamarin, I heartily recommend investigating MonoTouch if you're a .NET developer that wants to get to the iOS AppStore quickly. I had to take several detours along the way (converted my existing app from Lightspeed to EF4 CodeFirst, converted to use POCOs, had support obligations, and wrote a sync engine to communicate over ServiceStack, but in the end, things lined up pretty well.

Some of the highlights:

  • I had to write code to essentially mimic the context loading that EF would do for you. This included fixing up object references as well as reading and writing from the SQLite database. Not horribly difficult, but it was something I'd rather I didn't have to do.
  • I encountered a couple of problems executing various LINQ statements when running on the device. A quick test case, and the devs at Xamarin had me with either workarounds or fresh bits to solve my problems.
  • Be sure to embrace threading when making web calls - especially on startup. You have 15 seconds to have your app launched on the device, or the device will think it is hung and kill the app.
  • Deploying to the app store has been written about extensively as a complex and intricate process. It turns out, there's good reason for that. After I got through an error due to linking my release build to ServiceStack.Text.dll, the resulting upload to the app store was failing verification. For some reason, the application name of RouteBoostiPhone.app was not being accepted. I changed the name to RouteBoost.app and it sailed right through. I have no idea exactly why this was required, but there you have it.
  • MonoTouch.Dialog is a very nice framework for building a line of business app. Be sure to check it out.

When I look back on the road I travelled to get my app to the app store, I'm impressed with how much of the business logic I was able to carry over. The time savings in being able to bring my business logic across as POCOs that have been extensively tested in production over many years was the real reason I went with MonoTouch to begin with. I most definitely do not regret that decision.

Note: I was not compensated or asked to write this post. I am just a happy paying customer of a product that saved me time, and I wanted to share my experience.
