Many programmers, open source developers, hardware gurus and IoT masterminds have been taking their craft to online streaming platforms such as to share with the world what they are doing. Some people are running their live coding sessions as a tutorial and others are just coding. People are watching, and it is really fascinating to watch how other people write software.

When adding custom animations to your Xamarin Applications don't immediately jump to the custom renderers and platform specific code, it is not needed. Often overlooked the Xamarin.Forms Animation APIs can usually handle your mobile apps animation needs. The APIs are built right into the platform so you can be confident your code will work across the platforms your application is being built for.

When building Xamarin Apps there is no easy out of the box mechanism to control your enviornmental settings such as web service url as your app migrates through the different environments such as Development, Staging and Production. With a little work we can add a configuration file very similar to how you would update a web.config or appsettings.json in an ASP.NET or ASP.NET Core application

When I am developing a DNN Module or even a DNN Platform change I typically configure my development enviornment to output the assemblies in the bin directory or I manually copy over the assemblies and the pdb files. This turns into a very tedious process very quickly when I am trying to rapidly develop or debug DNN Code.

Image Manipulation is a powerful utility provided by .NET that can make really cool applications or tools depending what you are building. We have worked in both patterns building developer tools using basic image manipulation and production applications that required thumbnail and compression algorithms before we served images to the user.

When building a test framework it is sometimes useful to be able to write test code against DbSet<T> objects. Since DbSet<T> implements IDbSet<T> it is relatively easy to wire up a mock for your entity. Before we jump in let’s go over an important concept in the Moq framework.

On my Xamarin.Forms project I am using an Untrusted Certificate (SSL) just for development on my local machine and with the development servers. This has caused several headaches and issues while trying to code around it on VPN. The latest issue that has popped up was exceptions being thrown regarding untrusted certificates when trying to access images off of the development server.

At the end of my last project I spent some time getting touch gestures to work on a WPF application. This was surprisingly easy and difficult at the same time. This will be part 1 of a 2 part blog series which focuses on Multi-Touch in WPF applications. Part 1 will focus on simple multi touch events and part 2 will dive into a more complicated real world example with an open source project I forked on github.
