WIF: Enable tracing

WIF(Windows Identity Foundation) is not the most easy framework to use. The moment something goes wrong it’s not always transparent what actually happened leaving you no clue where to search for the root cause.

Luckily Microsoft integrated great tracing functionality so you can have a look under the hood. To enable tracing, add the following configuration to your app.config/web.config file:

<system.diagnostics>
<sources>
<source name="System.IdentityModel" switchValue="Verbose">
<listeners>
<add name="xml" type="System.Diagnostics.XmlWriterTraceListener" initializeData="WIF.svclog" />
</listeners>
</source>
</sources>
<trace autoflush="true" />
</system.diagnostics>

Tracing information will be written to a file in XML format. However you can use the SVCTraceViewer tool to open and read the trace messages in a more user-friendly format.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...

.NET 9 - Goodbye sln!

Although the csproj file evolved and simplified a lot over time, the Visual Studio solution file (.sln) remained an ugly file format full of magic GUIDs. With the latest .NET 9 SDK(9.0.200), we finally got an alternative; a new XML-based solution file(.slnx) got introduced in preview. So say goodbye to this ugly sln file: And meet his better looking slnx brother instead: To use this feature we first have to enable it: Go to Tools -> Options -> Environment -> Preview Features Check the checkbox next to Use Solution File Persistence Model Now we can migrate an existing sln file to slnx using the following command: dotnet sln migrate AICalculator.sln .slnx file D:\Projects\Test\AICalculator\AICalculator.slnx generated. Or create a new Visual Studio solution using the slnx format: dotnet new sln --format slnx The template "Solution File" was created successfully. The new format is not yet recognized by VSCode but it does work in Jetbr...
