👀 Just show me the code already With the upcoming release of .NET 6, we're also getting a new API to build applications. This new API is called the "Minimal Web API". This blog post came to life because seeing this new structure triggered some new brainwaves that made me question my current project structure. After having read about CUPID by Dan North these thoughts have only amplified. Before we

I recently came across the need of hosting a .NET assembly (DLL) as an out-of-process COM server. While .NET ships with excellent support for COM interoperability, this particular scenario isn’t directly addressed by the interop layer. While there are some fairly complex solutions such as COM+ hosting or custom class factory registration, I would like to show you how to accomplish this task using

Running non-root .NET containers with Kubernetes - .NET Blog
Rootless or non-root Linux containers have been the most requested feature for the .NET container team. We recently announced that all .NET 8 container images will be configurable as non-root with a single line of code. This change is a welcome improvement in security posture. In that last post, I promised a follow-up on how to approach non-root hosting with Kubernetes. That’s what we’ll cover tod
In this post I describe Windows named pipes, what they are, the scenarios where they're useful, how to use them with ASP.NET Core, and how to call a named pipe ASP.NET Core app using HttpClient. What are Windows named pipes? Windows named pipes provide a named, one-way or duplex pipe for communication between a client and a server. They provide a way to communicate between different processes, typ
Last weekend I migrated the Giraffe web framework from AppVeyor to GitHub Actions. It proved to be incredibly easy to do so despite me having some very specific requirements on how I wanted the final solution to work and that it should be flexible enough to apply to all my other projects too. Even though it was mostly a very straight forward job, there were a few things which I learned along the w
Porting a C++/CLI Project to .NET Core - C++ Team Blog
One of the new features of Visual Studio 2019 (beginning with version 16.4) and .NET Core 3.1 is the ability to build C++/CLI projects targeting .NET Core. This can be done either directly with cl.exe and link.exe (using the new /clr:netcore option) or via MSBuild (using <CLRSupport>NetCore</CLRSupport>). In this post, I’ll walk through the steps necessary to migrate a simple C++/CLI interop proje
Secure your container build and publish with .NET 8 - .NET Blog
.NET 8 raises the bar for container security for .NET container images and SDK tools. The SDK produces application images that align with industry best practices and standards, by default. We also offer additional security hardening with Chiseled images for an extra layer of protection. dotnet publish will generate a container image for you and configure it as non-root by default. It’s easy with .
I’ve decided to make a series of at least 8 free weekly-based webinars about in-depth implementation details of the .NET GC and… I’m super happy with it! Why the idea? Many my other activities are about more practical “.NET memory management”, like my book or workshops/trainings/consultancy I gave. But during all this practical-oriented events there is always not enough time to explain in details
