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…


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 =


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

It’s been a long time since we had a geek BBQ! No PowerPoint’sPowerPoints or projectors on the beach, we use White Boards and flip charts for beach meetings. Battery power only for laptops.  We might have a Brighthouse signal there. I will check that, but count on no internet. We will have the big hut with the huge grill, so this event is on rain or shine. It’s a county park so this is $2 parking with incredible sunsets. There is a playground for kids. Walking trail lookout over the Gulf where you can see houses on stilts in the water. No bottles on beach. See park rules and general info here for Green Key beach.

Event starts at 3PM (eat at 5) and runs until sunset, which should be about 8:30 .

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

It was a packed house! Greg Leonardo was working on my AV here.   It is funny, I once did that for him a few years back at one of his sessions. Full circle, huh?


First Demo, Xamarin Forms Hello World in iOS, Android, and Windows Phone. This got a big warm round of applause!

Russ Fustino, Xamarin Developer Evangelist!

Hello all! I am happy to announce I am the new Developer Evangelist for Xamarin! I am so excited about this next chapter in my career. I am looking forward to learning and teaching one of the hottest set of software products on this planet, which will help the lives of many fellow geeks! It is a very rewarding position indeed and I am on cloud 9. Everyone I have met at Xamarin is awesome and I look forward getting to know the entire team.

For those that unfamiliar on what Xamarin does… we produce software for programmers which facilitates creating the same mobile app, natively, on multiple platforms such as Windows Phone,  Android and iOS. It is a ‘must have’ tool in the industry with some incredible recent announcements on the new version Xamarin 3.



I will be traveling up to the Boston Xamarin office on occasion and I look forward to seeing all the “Shed Heads” back home. So, New England crew, get those lobsters ready!

And of course, I will be hitting up all the conferences for speaking engagements in and around Florida and all over the country. Drop me an email if you are interested in having me speak at your user group or conference. My new email at Xamarin is russell.fustino@xamarin.com .

I also setup a new twitter @RussFustino with my actual name (about time huh?). Please follow! I will have more details on my Xamarin blog once it gets set up. Stay tuned and follow me on twitter. Thanks!


Xamarin 3 Rocks! Tampa Xamarin Meetup Recap

I had the great pleasure of attending the Xamarin user group in Tampa the other night.  Xamarin 3 was recently announced on May 28, 2014.  James Montemango, Developer Evangelist for Xamarin, delivered a killer online session for the Tampa Xamarin User Group. The folks at the meeting were very appreciative of the fact that James took the time to present to us.  We had a packed house at the AgileThought office to see all the new features of Xamarin 3. Wow. Everyone was blown away. I overheard one attendee saying on the very next day, he would pitch  to his boss to get Xamarin licenses for entire staff at his company. So, I guess it was a successful meeting! Special thanks go to Michael Stark for heading up the new group and organizing this meeting with James.


James Montemagno delivered a session to Tampa from Seattle on Wednesday night at the Tampa Xamarin User Group.


MVPs Kevin Wolf and yours truly, Russ Fustino were in the house.

James gave a quick overview of Xamarin and  covered the Xamarin Designer for iOS as well as Xamarin Studio & Visual Studio Enhancements.

Local developer,  Imaya Kumar, then showed off the new Xamarin Forms!


Imaya Kumar, Solution Architect Convene Technologies

Here are my notes from the meeting:

  • C# on 2.6 Billion devices! Yes, billion not million!
  • Xamarin 3 is the best release yet!
  • Xamarin Mission Statement: Make it fast, easy and fun to create apps.
  • The third year of the company was celebrated with a Birthday cake! Happy Birthday Xamarin!


Birthday Cake and Pizza were provided by Xamarin!

  • Xamarin is seeing explosive growth with strong recognition from the Gartner Magic Quadrant as a Visionary :


  • Xamarin has a test cloud for all of the different Android devices. Wow! So, now you don’t have to buy all sorts of Android devices to test with.



  • Users prefer to use Native apps that are fast, smooth and deliver a great experience. Hybrid apps typically don’t get good reviews. For example,  Facebook switched to a native interface and the downloads doubled.


  • F# and C# are supported.
  • New meaning to “write once and run anywhere”.  Shared C# backend  code is typically  %75 of the code, but  now the UI code can be sharable too, raising that number even higher!
  • All native API’s are supported and are made available to C# Developers.




  • Xamarin University is the quickest way to become a Mobile Developer? Numerous classes in all time zones are available 6 days a week with live training.

Major elements in Xamarin 3

  • Xamarin Designer for iOS
  • Xamarin Studio & Visual Studio Enhancements
  • Easy code sharing
  • Xamarin.Forms

Xamarin Designer

  • iOS provides and intuitive interface for developing iOS apps. For example, when you double click on an item in the designer it opens a code windows for the default event handler, etc.
  • Comprehensive editor, auto layout, etc.
  • iOS6 and iOS7 are both supported
  • Works on Windows and Mac

Xamarin Studio

  • Handy for those that don’t’ have Visual Studio and the interface has been improved. NuGet Package manager along with integration with Xamarin Component Store provides ease of access to many libraries.
  • Easy assess to solution
  • Main panel has new information from Xamarin, blogs, etc.

Visual Studio and Xamarin Studio

Easy code sharing

  • Shared project support
  • Editing can be in the context of the editing container. For example,  Android code is grayed out when in the iOS context.


  • Same project can be opened in both VS and XS
  • Build Story Boards to provide app functionality
  • iOS has native calls for face detection and sepia color editing, since 100 percent of the calls are available in Xamarin, this is no problem.
  • Custom Controls can be built as well
  • Screen shots of sample custom control, to crop and apply sepia filter


Auto Crop (uses automatic face detection in iOS): provides real time update in designer.


Sepia filter:


Xamarin Forms:

Besides the Xamarin Birthday cake, Xamarin Forms was the topic I was the most excited about! Can you imagine using shared code for multiple platforms. Wow!


  • Build native UI’s for iOS, Android and Windows Phone from a single shared C# codebase
  • uses XAML like code for the Xamarin compiler

With Xamarin Forms you can…

  • build the entire app with Xamarin Forms…
  • or use this to prototype, leaving the door open to incorporate  further platform specific features…
  • or take an existing project and add a new page, build you don’t want to do that three times

Pages, Layouts and Controls oh my!

  • Controllers are provided for pages using Master Detail , navigation, tabbed pages and more
  • Layouts are provided for stack, Absolute, relative, grid and more
  • Controls, controls and more controls. Being a former developer evangelist for control vendor, this is huge!




I am about to update my Tull Tribute Windows Phone app (to be renamed Jethro Tull, which is endorsed with Tull assets). There is no doubt in my mind when porting to iOS and Android, I will be using Xamarin to to this.

If you missed the meeting, don’t worry… here are links to the deck and a recording of the announcement of Xamarin 3. The video features Xamarin’s Nat Friedman, CEO and Co-Founder, Miguel de Icaza, CTO and Co-Founder and James Montemagno, DE.
