Last week at Build 2025 a new way of running C# applications were introduce in which there is no need for a csproj files! This could help getting started with C# easier and more like python, node, or go! Let's take a look into it together!
So far we looked into Diagnostic Analyzers and Code Actions from the perspective of a creator! What if we switch roles and take a look from the consumer's view point of those tools!
In the previous post in the Roslyn series we have explored how we could create code analyzers and how to test them, to reduce the cognitive load on our development team! However, what if we take an extra mile and create a Code Fix Provider to provide some suggestions for the developers! Shall we?
As a developer if you are using Azure for cloud development, one of the first things to do is to authenticate your machine against Azure environment so that Azure knows commands issued against it are from a trusted machine! This is important to also eliminate the need of using connection strings as far as possible! Let's see how easy it is and how it could be done!
In the previous post we have seen how it is possible to create a diagnostic analyzer using Roslyn APIs. Being a TDD advocate it would be disappointing not to talk about how we could test our code analyzer! So let's take a look into it.
We are all familiar with diagnostics that are provided from the compiler when we develop an application, they could be in form of warnings, errors or code suggestions. A diagnostic or code analyzer, inspects our open files for various metrics, like style, maintainability, design, etc. However, sometimes we need to write a tailor-made analysis for our specific situation, tool, or project.
A syntax tree has knowledge about the textual content of what it represents and that content relates to C#. There are scenarios that we need to change the code, such as code fixes, refactorings, or advanced source generation, and it could be done through changing the syntax tree; since this is a bidirectional relationship. There are two approaches, Replacement Methods and SyntaxRewriter classes
I had a discussion on a meet-up a month ago with a friend of mine, and he was telling me it is not really easy or clear how one could create a simple web application in .NET and C#. Hopefully this post is going to help that friend of mine! 😊
Sometimes when we want to generate code whether it is source generators or code fixes for a code analyzer, it is required to know how a syntax tree could be created using the Roslyn Compiler API. There are two ways, that we will discuss them in this post.
Compilers used to be a black box, they were accepting a bunch of source files as input and were producing an artifact as an output! There were no means of interaction with any of the phases inside the compiler pipeline. However, with Roslyn, The .NET Compiler Platform SDK, it is not the case anymore!
