Dapr is an impressive set of APIs for building distributed applications with any language and platform. It provides a set of building blocks that you can use to build microservices. Dapr is based on sidecar architecture. Meaning that you need to run a Dapr sidecar for each of your applications. How do you debug your Dapr apps effectively? If you have been using PowerShell scripts to run and attach your debugger, you know how tedious and error-prone it can be. Ready to see how to use Rider or Visual Studio to debug your Dapr apps with ease and confidence?Continue reading
With my team, we like to keep our C# code base updated. So, recently we went to .NET 7 and C# 11. At the same time, we were still adopting some of the new capabilities of .NET 6 and C# 10. Our code base is large, so it takes some time. One of the new features that we planned to use was the
ArgumentNullException.ThrowIfNull method, which throws an exception if an argument is null. In this post, I will show you how I effortlessly did that refactoring by letting the machine work and not the human 😁 (me). In the past, I used the same approach to migrate lots of code that used
Assert.That(, Is.True) and for some other even more complex cases. We will use ReSharper and Rider for that.
On October 24th, Docker announced the support of WASM and WASI in a new technical preview release. I wanted to try it out and see how it works with .NET 7. If you want to know more about WASM and WASI you can read the introduction from my previous post, “Using WASM and WASI to run .NET 7 on a Raspberry PI Zero 2 W“.Continue reading
I am using a tool called logseq to manage my notes. It is a fantastic tool, and I would like to be able to extend it. I am not an expert web developer, but I am a .NET developer. I would like to be able to write plugins for logseq using .NET and C#. I have found a way to do it using WebAssembly. In this post, I am going to show you how to do it.Continue reading
In the past, within my team at Innoveo, we had several discussions about the best way to unit test async WPF ICommand. We value quality, so testing is essential to us. We decided to make the methods called by the command
internal so that our tests could call those.
What is the problem with unit testing an Async WPF ICommand? The problem is that the command is an
async void method! So, you have no way to
await the end of the execution of your command. So, your test might assert on things that are still executing.
Early in my journey in developing software, I used to start a project by setting first a way to build my software automatically each time I did a set of changes. Long, very long ago, I used scripts scheduled to run. When JetBrains shipped TeamCity I started to use it extensively for my projects, here is my first post about “Set Up a Build Computer using VisualSVN, Team City, MsTest, NUnit“ from March 21, 2008, but used it since version 1.0. Later on, I also used Azure Pipelines to build Git Diff Margin and also GitHub Actions, for example, to build and deploy those pages.Continue reading
Till now, we have seen two Dapr building blocks which are the service to service invocation building block and the secrets building block. The secret building block serves to protect things like a database connection string, an API key… so that they’re never disclosed outside of the application. The service to service invocation building block serves to make calls between services in your distributed application easy. In this post, we will introduce a third one which is the bindings building block. The bindings building block enables your distributed application to handle external events or invoke external services.Continue reading
In all previous posts, we were looking at the Dapr service invocation building block. We have seen how to expose and call HTTP and gRPC services using it. In this post, we will see how Dapr ease developers life when it comes to deal with secrets, thanks to the secrets management building block.Continue reading
In previous posts, we focused on Dapr service invocation using the HTTP protocol. Dapr, through its service invocation, can also reliably and securely communicate with other applications using gRPC. We will have a look at this other capability in this post.Continue reading
In the last post, we have seen how to call a service from another service using the Dapr .NET SDK. In this one, we will have a look at a possible way to simplify the development of the client code using Refit, the automatic type-safe REST library for .NET Core, Xamarin, and .NET.Continue reading
