Retiring as a Microsoft MVP
I have decided to retire from the Microsoft MVP program. In the first week of April, an e-mail from Microsoft landed in my mailbox. I was given the choice to either remain an active MVP (but without access to NDA content) until my next renewal period, or retire from the program. Read more »
Running Kotlin in Azure Functions

Extending .NET CLI with custom tools - dotnet init initializes your NuGet package
A few weeks back, .NET Core 1.1 was released (and a boatload of related tools such as Visual Studio 2017. For .NET Core projects, a big breaking change was introduced: the project format is no longer project.json but good old .csproj.

Using dotPeek to figure out why IIS crashed
Here’s a story on how I once used dotPeek to provide debugger symbols and (decompiled) source code for a crashed application for which we had nothing but the application assemblies available. Namespaces have been altered to protect the innocent. Read more »
