When I created my first analyzer, half the battle was converting the project to be compatible with.

BEST VISUAL STUDIO EXTENSIONS 2017 INSTALL

You had to install various extensions from the Visual Studio marketplace, and even then the project templates produced PCL projects, which requires a different build chain to normal. Up until recently, creating a Roslyn Analyzer that could be consumed anywhere was a bit of a chore. This will highlight framework API calls that are deprecated, or which might throw PlatformNotSupportedExceptions on certain platforms.

If you're writing cross-platform code (or even if you're not) I strongly suggest installing the API Analyzer. If you're using an editor other than Visual Studio, you won't get these UI enhancements, but by referencing the NuGet package you'll still get the compiler warnings and errors when you build your project. You'll see green/yellow/red squigglies depending on the severity associated with your analyzer, and you can even associate your analyzer with a Code Fix to perform automatic refactorings: In Visual Studio, analyzers installed as extensions or as NuGet packages hook into the UI. On the other hand if you reference the analyzer as a NuGet package in a project, everyone who builds your project will see the same compiler warnings and errors, you just have to remember to install it If you install the analyzer as a VSIX extension, it'll automatically be used in all of your projects, but other people building your projects won't use the analyzer. You can use these to enforce naming styles and code conventions, or to flag particular code patterns, such as the missing await in the above code.Īnalyzers can be distributed either as a NuGet package, or as a VSIX extension for Visual Studio. What are Roslyn analyzersĪnalyzers are effectively extensions to the C# Roslyn compiler, which let you add extra warnings and errors to your code, in addition to the standard compiler errors. In a later post, I'll show the solution we came up with for the above problem.

BEST VISUAL STUDIO EXTENSIONS 2017 HOW TO

In this post I'll introduce analyzers in general, and show how to get started. Naming conventions and code-reviews can go some way towards mitigating the issue, but it seemed like there should be a more robust technical solution for detecting un- awaited tasks. Once we identified the problem, the question was how to prevent it happening again. on this blog or in GitHub), the Async suffix is the only indication that there's anything awry in the second call.

Even with a rich IDE like Visual Studio, the issue in the above code was not picked up - when reviewing code statically (e.g. By awaiting a single Task, the compiler was satisfied, and no warning was issued for the second method.Īs an aside, this is one of the main arguments for preferring the Async suffix for async methods. The problem was, we were using await for some of the calls in the offending method, just not all of them. For example public class TestClass īy default, you will get compiler warnings if you don't use await inside an async method. This was causing concurrency issues that were hard to spot in the code, as everything compiled correctly. Long story short, eventually the issue was traced back to a Task not being awaited. I was recently investigating some strange bugs which would only sporadically manifest in an ASP.NET app recently. Be sure to check it out in the run up to Christmas for a new post every day! Why create a Roslyn Analyzer?

This is my post for the C# Advent Calendar. As the code in Roslyn analyzers can be a bit complex, I'll look at the actual code for the analyzer in a subsequent post - this post just focuses on getting up and running. NET Standard using the new Visual Studio 2017 (15.5) templates, and show how you can debug and test your analyzer using Visual Studio. I'll show how to create a code analyzer that targets. In this post, I give a brief introduction to Roslyn analyzers, what they're for, and how to create a simple analyzer in Visual Studio 2017.
