2code ^ !2code [S2026E03] Inspector Roslyn and the NuGet Package YouTube video by FlashOWare

With the previously acquired skill to inspect Roslyn Components and all their Compiler Extensions,
it is time for Inspector Roslyn to apply this skill to NuGet Packages.

And we're back!
Starting into the premiere Episode of Season 2026 of #2codeOrNot2code by announcing our brand-new and year-long (and probably beyond) project, perhaps even our Opus Magnum.

In two days, we finally start a new year of awesome events!
And we start big! Alex Thissen is coming to Vienna to talk about DevContainers!

Thanks to RUBICON IT GmbH for hosting us!

...
With that being said, I might host my blog at a custom website in the future. Especially considering that @merelyeva.bsky.social and I are about to start coding a UI-heavy Roslyn-based inspection tool—gaining Web-UI experience—during the #2codeOrNot2code live stream: see @flashoware.bsky.social

...
GitHub as a host has plenty of features already built in: Markdown & Code rendering, Discussions, watching notifications, fixes via PRs, git History, automation via Actions/Workflows, Stars & Sponsors, and simply clone the repository for a local copy to feed the context of AI-powered tools.
...

I was contemplating a custom website indeed, bikeshedding to infinity and beyond, resulting in me procrastinating the launch of my blog for years. My New Year's resolution is to Just Do It!
...

At long last: my very first blog post.

Thank you @csadvent.christmas for this incredible kick-starting opportunity. My next blog post is already (early) in the making, and here's to more to come in 2026: Cheers!

Thank you so much for your uplifting feedback @bayn.es. I am really glad you liked my session.

I just left a couple of rough months behind me, so your kind words are a true pick-me-up for my spirit.

You are very welcome.

We are now starting a series on #Benchmarking #Roslyn Compiler Extensions.

We begin with setting up the project and building a first prototype.

2code ^ !2code [S2025E08] Benchmarking Compiler Extensions - Part 1 YouTube video by FlashOWare

The (run)time has come!
We allocate this series to build a library that supports Benchmarking of #Roslyn Compiler Extensions, like #dotnet Analyzers and #CSharp Source-Generators.

Can't wait till Saturday.

We're building up to it:
Today, we will inspect, together with @kevingosse.net, what methods and calls really are

bsky.app/profile/flas...

and then - probably next episode - kick-start our journey of Tools for Roslyn Compiler Extensions; starting with Benchmarking.

We'll ping you when announced.

Let's dive deep into the #CSharp Dispose Pattern.

Not quite yet.
But we are about to get back into live-streaming next week, and will be building up towards Benchmarking of Roslyn Compiler Extensions.
I'll get back to you once we actively start that endeavour.

From what I read is that "Compiler-Extensions" is the official term used in (limited) documentation for Plugins that Roslyn-Hosts may load for compilations (Analyzers, Suppressors, Generators) and IDEs/Editors may interact with via Workspaces (Fixers, Refactorings, Completions).

Also ... so I think, I'm not positive though ... that, technically speaking, if your Extensions only use types that they are safe/meant to use, in accordance with the respective [Attribute], you should be fine putting all together in a single Assembly and it should work for the most common scenarios

...

Example:
Should you use a type from "Microsoft.CodeAnalysis.CSharp.Workspaces" in your Analyzer or Suppressor or Generator, but your Extension is loaded in a Build/Compilation-Scneario (only Editor-Scenarios usually require the Workspaces-APIs to be loaded), then your Extension might not work.

...
The reason for this guideline is that Roslyn is a Library which can be hosted by any tool, so the Extension-Author does not necessarily know under which environment the Compiler will run and whether, e.g., the Workspaces-Assembly is loaded or just "Microsoft.CodeAnalysis.CSharp/VisualBasic".
...

...

And for NuGet, you can pack them together in PackagePath="analyzers/dotnet/cs".

I usually have a separate CSPROJ that only represents the NuGet package and packs all netstandard2.0 libraries together.

...

I love/hate to say: It depends.

For maximum compatibility and safety, separate Roslyn-Extensions by Diagnostics-API (Analyzers + Suppressors + Generators) and Workspaces-API (Fixers + Refactorings), as well as separate Compiler-Extensions by Language (Common / CSharp / VisualBasic).
