The message can appear in any service trying to retrieve active Azure Resources either within Azure Portal or from any 3rd party consumer. As an example, it can appear while trying to create an Azure Resource Manager service connection in Azure DevOps.

Docker cheatsheet for .NET Core
This is just a cheat sheet of commands and terminology for Docker and ASP.NET Core; it contains commands that you can find in the original cheat sheet, plus a
Dockerfile for ASP.NET Core and a quick guide on how to created one from Visual Studio. Hopefully, both developers that are in the process of getting into the containerize world with Docker and developers that are already in but need a quick recap will find it useful.
It may be that .NET 5, the one and only .NET that will clear the confusion and lead the way for the next years was probably the biggest(?) announcement of Microsoft Build 2020, but there were numerous other equally important; from the general availability of the Blazor WebAssembly, the Azure Static Web Apps and all the projects related to IoT and Artificial Intelligence, all the way to .NET MAUI (short for Multi-platform App UI), Visual Studio Codespaces, Entity Framework Core 5, Project Tye, Azure Quantum and the multiple new features and capabilities of Azure Cosmos DB.
Although there were many more interesting things, C# 9 was left out intentionally because in this post we will deal with some of its exciting new features!
GIT cheat sheet
I know there are many cheat sheets around (here is one I like from GitHub) but I couldn’t find many that contain sequence of commands, from clone to merge and push. This is my version of a cheatsheet which I hope you will find useful.
How to make authenticated requests to an ASP.NET Core web API using IdentityServer4 with Client Credentials.
This is a guide on how to make requests to a protected resource using Client Credentials with the IdentityServer4.Contrib.HttpClientService nuget package. The library is actually an
HttpClient service that makes it easy to make authenticated and resilient HTTP requests to protected by IdentityServer4 resources. Additionally, more features include automatic complex type serialization for requests / deserialization for responds (using
Json.NET), caching of the token response to reduce load and an
HttpRequestMessage factory that adds an “
X-HttpClientService” header for logging/tracking between cascading API calls.
