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

As outlined by Joe Duffy, LINQ introduces inefficiencies in the form of hidden allocations, from The 'premature optimization is evil' myth: Good question, who knows, probably only Jon Skeet can tell just by looking at the code!!

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

There are several great resources on the Internet about using the new Configuration and Options framework of ASP.NET Core - like this comprehensive post by Rick Strahl.

I needed this video of running an example app through the Desktop App Converter from start to finish and so I'm sharing it here too; For full details, go to MSDN. Feel free to borrow that video if you have a use for it at your own events etc.

I decided to prepare a simple Step by step: ASP.NET Core on Docker sample

Today we’re excited to announce the final release of TypeScript 2.0!

1, 2, 3, GO! Run IIS in Docker on Windows Server 2016

It's new, shiny and all the cool kids are using it, but is Core right for you? If you're just setting out with .NET Core (as most of us are) you're starting with a lot of the landscape hidden from you. Here's a rough plan of action to help you get started.

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 ...

Creating a service for unknown technology is usually painful. Sorry, "service" is an unpopular world, nowadays we call it an API. For a few years, everybody says: let's create some REST service. Cool, flexible and uneasy to consume. Exactly uneasy - it is not a mistake, uneasy is a correct word.

Pull requests have been widely accepted as a best practice for teams using Git to peer-review code changes. Peer reviews are a great practice for discussing how to improve code and for spreading knowledge about a codebase amongst team members.

TL;DR - I like the CoreCLR, project.json project system, and the new dotnet CLI so far, but there are a lot of differences in API that could easily burn you when you try to port existing .Net code to the CoreCLR. As I wrote about a couple weeks ago, I've been working to port my...

Today we are releasing our new output format, a simpler schema that will cover most end-user scenarios with less headache

today we’re releasing the CSP Evaluator, a tool to visualize the effect of setting a policy and detect subtle misconfigurations

This week we are rolling out our sprint 106 work. Here are the release notes. By now, the update has made it out to most customers and it should finish by the end of the week. Overall, sprint 106 was a modest sprint. It has lots of nice, relatively small, improvements and nothing particularly earth shattering.

You ever take over a codebase where the previous developer liked to ignore exceptions?

I've recently enabled support for Facebook Instant Articles, Google AMP, and Apple News on this blog following this enlightening article. It wasn't exactly plain sailing; AMP needs a logo, and a featured image set for every article (both of which must be above a minimum size); the Instant Articles plugin has a feed url which my feedburner plugin breaks; Apple News needs some real tweaking, but still strips out code blocks from posts.

Version 0.16.0 of Cake has been released, and it's a big release!

We have now released TFS "15" RC2. We are using it in production internally. It is fully supported for production use. You can upgrade from TFS 2012 or newer to RC2. You can also upgrade the RC1 release to RC2, and you will be able to upgrade from RC2 to RTM (that should be a very fast upgrade, since there will be very few changes between RC2 and RTM).
