7 Scenarios on covering how to deploy ASP.NET, NancyFX and F# applications as Docker Containers

Ever wonder how to become a Microsoft Most Valuable Professional? Lisa Anderson, a Microsoft community program manager (CPM) for the central region of the United States, explained what she looks for recently at That Conference 2016, a summer camp for geeks, when she sat down with Channel 9's Seth Juarez.

Xamarin.Forms ships with over 40 pages, layouts, and controls for you to mix-and-match with to build great native, cross-platform user interfaces. One of my favorite features of Xamarin.Forms is that we have access to 100% of the controls and APIs for iOS, Android, and Windows.

F# xUnit library supporting better testing

I was on another whirlwind trip back in July, this time to a bunch of spots in the US which included Chicago where Pluralsight has one of their offices. The last time I was there I'd recorded a "Play by Play" course which is video recorded rather than a screen

One of the things that we have learned from supporting RavenDB in production is that you by default, everything is a black box into which you have exactly zero input. And in order to figure out what the problems are, you need to use expert tools (WinDBG or VM MAP for example) that are typically more focused on developers, and not usually available in production.

Functions are the reason why many nice features become hard or impossible to implement. Functions make type inference hard and they make it impossible to use tools that rely on manipulation with concrete values - because functions introduce names with unknown values and types.

PSYaml is a simple PowerShell module that I've written that allows you to serialize PowerShell objects to "YAML Ain't Markup Language" (YAML) documents and deserialize YAML documents to PowerShell objects. It uses Antoine Aubry's excellent YamlDotNet library To start, you can simply load the PowerShell file and the manifest from its home on GitHub PSYaml ...
