Building Your App On App Center

In my previous (and first) blog post on App Center I talked about getting started, adding the SDK to your code, and looking at Analytics and Crash reporting.  In this post I’d like to discuss building your app on App Center; which allows you to distribute your app to Beta testers and others.

There are a few steps in setting up and configuring your build process, but once done, building is as simple as pressing a button (or, even simpler, you can set it up to build on every push to your source control!)

Getting Started with VS App Center

There is no doubt that Microsoft’s VS App Center is an incredible resource for mobile application programmers.  The problem is that it seems hard to get started.  The good news is that once you get started, it turns out to be wicked easy!

For this blog post, I’m going to assume that you are already sold that App Center is the Cat’s Meow; if not check out this article by Microsoft on why App Center is so cool.

The short version is that App Center allows you to Build your application in the cloud, directly from your repository. You can Test (using Xamarin Cloud) and you can Distribute to beta testers.  You can also set up and view analytics and crash reports.  Finally, you can set up push notifications.

In the next few blog posts I’ll go over each of these areas, and be sure to keep an eye out for my forthcoming course on App Center on LinkedIn Learning (part of my Azure Essentials series) .  You’ll find these posts on Wintellect’s blog and on my own.

Creating A Generic Report in Xamarin.Forms

I recently had a client who wanted to create simple reports that consisted of a variable number of columns, followed by a “more” button that takes you to a page with the full details. 

The problem was that they didn’t want to hard-code anything.  They wanted the ability to add reports without sending out a new version of the software, and they wanted to be able to pick which columns were visible.  Yikes!

Building A Generic SQLite Repository

In a recent project, I found myself needing multiple, seemingly unrelated databases.  It was crazy to copy and paste the code for such basic operations as getting all the data, etc., so the obvious alternative was a generic repository, and a database with tables for each set of data.

The first step is creating the SQLite repo.  We begin by creating the class:

public class GenericSqliteRepository<T> where T : IEntity, new()

Getting a PDF from a remote host to a Xamarin.Forms Application

It is fairly easy to display a PDF file that is local to your phone.  For example, see this article from

A bit trickier is to get a PDF from a server and then to display it.  Here’s how I did it (note, this blog post offers snippets of code, rather than a complete solution… I will reduce my larger program to something manageable asap)

The first thing I did was create a model object named ReportItem. Its primary goal is to help group all the items in my list of pdf’s, but it contains the all-important URL to the pdf itself.

Next, I created a page named ShowPDFPage.  In the XAML part of this page I just have a CustomWebView:

         <local:CustomWebView Uri="foo.pdf" 
                               VerticalOptions="FillAndExpand" />

The CustomWebView was taken from an article I found on the web.

 public class CustomWebView : WebView
       public static readonly BindableProperty UriProperty = BindableProperty.Create (propertyName:"Uri",
       public string Uri
          get { return ( string ) GetValueUriProperty ); }
          set { SetValueUriPropertyvalue ); }

This performs the magic of showing the PDF file, but how do we get it?
