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 »

Application Insights telemetry processors

Two weeks ago I had a wonderful experience speaking at a small conference in Finland. The talk was titled What is going on - Application diagnostics on Azure (slides) and focused on the importance of semantic logging and how Azure Application Insights (AppInsights) can help make sense of that data and correlate it w...

Exploring .NET managed heap with ClrMD

Since my posts on making code allocate less memory and memory allocation for strings were quite well received, I decided to add another post to the series: Exploring .NET managed heap with ClrMD. In this post, we’ll explore what is inside .NET’s managed heap (you know, the thing where we alocate our objects), how it... Read more »

Exploring memory allocation and strings

A while back, I wrote about making code allocate less memory (go read it now if you haven’t). In that post, we saw how the Garbage Collector works and how it decides to keep objects around in memory or reclaim them. There’s one specific type we never touched on in that post: strings. Why would we? They look like val... Read more »

Making .NET code less allocatey - Allocations and the Garbage Collector

The .NET Garbage Collector (GC) is quite cool. In combination with the runtime’s virtual memory, it helps providing our applications with virtually unlimited memory, by reclaiming memory that is no longer in use and making it available to our code again. By doing so, it also takes away the burden of having to alloca... Read more »

Hotel California

At the start of 2015, I checked out from JetBrains to join Microsoft. Today, after almost two years in the NuGet team, it’s time for change. Microsoft and NuGet have been a fun ride, and I got to complete my personal mission… I remember Paul Stack trolling me (“Hey Maarten, is NuGet down?”) on more than one occasion... Read more »

NuGet and NPM news from the community

You may know (or not, shame on you!) Xavier Decoster and myself are operating MyGet, a hosted service providing teams with hosting and management of NuGet, npm, Bower, VSIX and debugger symbols. Recently, we started looking into how we could do better on the content marketing front, an important piece of getting peo... Read more »

Building NuGet (.NET Core) using Atlassian Bitbucket Pipelines

A while back, I signed up for the beta of Bitbucket Pipelines, a new continuous integration service from Atlassian, built into Bitbucket. The build system promises easy configuration using YAML files to describe the build steps. It runs builds in a Docker image, so that means we can also use it for building and pac... Read more »

Disabling session affinity in Azure App Service Web Apps (Websites)

In one of our production systems, we’re using Azure Websites to host a back-end web API. It runs on several machines and benefits from the automatic load balancing we get on Azure Websites. When going through request logs, however, we discovered that of these several machines a few were getting a lot of traffic, som... Read more »
