Deploying a SQLite database file with a Xamarin.Forms app–(UWP update)

Say you have a SQLite DB you want to deploy with your Xamarin Forms app. Here is an excellent article on how to do this from Rob Gibbens of Xamarin University fame…

http://arteksoftware.com/deploying-a-database-file-with-a-xamarin-forms-app/

The article has wp8 but it uses Application.GetResourceStream and that is only for Windows phone, and the code below I have updated for UWP. Also, in November the UWP team posted some great sample code where I found the answer at: https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/FileAccess

So, just replace the WP8 code in the blog article with this code below and you will all set. The iOS and Android code works fine in the blog.

var storageFile = IsolatedStorageFile.GetUserStoreForApplication();

if (!storageFile.FileExists(dbPath))

{
// copy storage file; replace if exists.
var fileToRead = await Windows.Storage.StorageFile.GetFileFromApplicationUriAsync(new Uri(“ms-appx:///people.db3″, UriKind.Absolute));

Windows.Storage.StorageFolder storageFolder =

Windows.Storage.ApplicationData.Current.LocalFolder;

StorageFile fileCopy = await fileToRead.CopyAsync(storageFolder, “people.db3″, NameCollisionOption.ReplaceExisting);

}

Great SD Times Article on Xamarin and Azure

I had the great pleasure of chatting with Microsoft RD Patrick Hynds and I contributed a few quotes to his latest article in SD Times Magazine on Azure.  We talked  about how Xamarin fits nicely into this scenario. Xamarin has an Azure Mobile Services Component in the Xamarin Component Store.

Enjoy a good read at:
http://sdtimes.com/follow-azure-road-cloud/

Xamarin is specifically mentioned on page 9:

Xamarin Forms session by Russ Fustino, Xamarin Developer Evangelist

Xamarin at Successful Tampa Code Camp! Recap

I had the great pleasure presenting Xamarin Forms at the recent Tampa Code Camp. This event was resurrected from a one year hiatus and a welcome site to the Tampa Developer Community. Many are looking forward to a bigger and better code camp as part of a very engaged developer community here in Tampa next year.

Personally, this was a huge moment in the next chapter of my career as well. I delivered my first Xamarin Session, concluding with three weeks of intense training and setup. It was a culture shock, of sorts, for me to present on a Mac and I joked about it that it was more of a challenge for me to learn a Mac than learn Xamarin! The Mac is a better presenting machine in that there are fewer moving parts to demonstrate iOS development. I still use my Windows machine to develop on. Anyway, it all turned out good as about 60 in my session learned about the Xamarin Platform and Xamarin Forms.  For most of the audience, it was their first exposure to Xamarin.

Here are is PowerPoint for the session: http://1drv.ms/1AbKxPp
