First up was Phil Pursglove, giving us a whistle stop tour of Cosmos DB, a new database platform that Microsoft are now offering on Azure. I’ve seen a couple of talks this year about Cosmos, and it looks really rather nice. It’s got protocol-level compatibility with MongoDB (what Microsoft call ‘bug compatible’), plus support for SQL and a couple of other language bindings. One of the coolest features of Cosmos is native support for multiple consistency models, allowing you to optimise your own application for your particular requirements - with the ability to override the global consistency model on a per-request basis. There’s a time-limited free trial available here - check it out.
Next up, Robin Minto gave us a run-through of OWASP ZAP, a proxy-based web security tool created by the Open Web Application Security Project (OWASP). ZAP is beautifully simple; you install it (or fire up the Docker image), it acts as a web proxy whilst you navigate through some of the primary user journeys on your web application, but in the background it’s probing your server and scanning your HTML for a whole range of common security vulnerabilities - and when you’re done, it’ll generate a security report you can share with the rest of your team.
James Singleton - author of ASP.NET Core 2 High Performance - gave us a very cool live demo of some of the cross-platform capabilities of .NET Core 2.0, including using his Windows laptop to cross-compile a web app for ARM Linux and running it live on a Raspberry Pi. What I found really impressive about this is that it didn’t require any .NET framework or runtime install on the Pi - it’s just vanilla (well, raspberry!) Raspbian Linux with a couple of things like libssl, and everything else is included in the deployment package created by the dot net tooling.
Ed Thomson, the Git program manager for Visual Studio Team System, did a great walkthrough of his open source project libgit2sharp - a set of C# language bindings for working with local and remote git repositories. If you’ve ever had to parse the output from the Windows git command line tools, you’ll know how painful it can be - but with libgit2sharp, you can use C# or Powershell to create automated build tools, manipulate your git repositories and do all sorts of cool stuff.
Ben Abelshausen came along to show us Itinero, an open-source route planning library for .NET which you can use within your own applications to calculate routes and analyse map data.
Finally, we had Matt Ellis from Jetbrains giving us ’Ten Jetbrains Rider Debugging Tips in Ten Minutes’ - including some really neat stuff like cross-platform support for DebuggerDisplay attributes and the ability to define interdependent breakpoints in your code.
