Stop Copy-Pasting Your Build Configuration
You've seen it before: Repository A uses TreatWarningsAsErrors, Repository B doesn't. One team enables nullable reference types, another pretends it's still 2015. Someone added a custom analyzer set to Repository C six months ago, and now it's three versions behind everywhere else. Configuration drift isn't dramatic – it's death by a thousand paper cuts.
MSBuild SDKs let you define your organization's "golden path" once and enforce it everywhere. We're talking project defaults, analyzer rulesets, shared props and targets, even standardized service registrations for logging and telemetry – all versioned, all opt-in, all maintained from a single NuGet package. When you update the SDK, every project that references it gets the changes automatically.
Walk away with a template you can adapt for your own organization – and finally stop playing whack-a-mole with Directory.Build.props files.
Psst... Roslyn Is Generating Code Behind Your Back!
Right now, as you type, Roslyn can be generating code you'll never have to write. No copy-pasting. No boilerplate. Just marker attributes, a generator, and code that appears in IntelliSense before you've finished your thought.
In this session, we'll dig into Roslyn Incremental Generators – the practical way: generating code with SyntaxFactory and Scriban templates, triggering generation from attributes and interfaces, processing additional files, reading MSBuild properties, handling multiple .NET SDK versions, packaging for NuGet, and testing with Verify.
Walk away, ready for your tooling to do the boring work while you're not looking.
The Price of Open-Source
Open-source is everywhere, and companies save billions of dollars because of it. Making your project popular an keeping a clear head takes a lot of effort. From my 7-year journey in the community, I learned from many mistakes and lived the versatile life of a maintainer. Open-source is an excellent opportunity for everyone to become a better developer and possibly even to create a sustainable business.
Audiences from different backgrounds will learn how to get the most out of open-source. No matter if you are a long-standing maintainer, an enthusiast with an idea for the next big thing, an occasional contributor, or a regular open-source package consumer.
Build Automation Revolution with NUKE
Solid and scalable CI/CD pipelines are essential for being competitive and creating a great product. But why are most of us a little afraid of touching YAML files and don't even dare to look at build scripts? Much of this is because C# developers are spoiled with a great language and smart IDEs, and they don't like missing their buddy for code-completion, ease of debugging, refactorings, and code formatting.
NUKE brings your build automation to an even level with every other .NET project. How? It's a regular console application allowing all the OOP goodness! Besides, it solves many common problems in build automation, like parameter injection, path separator abstraction, access to solution and project models, and build step sharing across repositories. To conclude your build revolution, NUKE can generate CI/CD configurations (YAML, etc.) that automatically parallelize build steps on multiple agents to optimize throughput!
Come to this session to make your build scripts loveable!
JetBrains Rider – Tips & Tricks
Rider is a powerful IDE from JetBrains, built for cross-platform .NET development. It streamlines your workflow with integrated version control, run configurations, database tools, and a vast plugin ecosystem. You’ll also get intelligent navigation, quick-fixes, refactorings, deep code inspections, and a robust debugger. More specialized support exists for many technologies, including cloud platforms and game engines. Rider now also includes an AI Assistant to help you generate code and unit tests, fix bugs, and explain exceptions or commit messages, allowing you to breeze through the most tedious tasks.
Whether you're new to Rider or looking to sharpen your skills, this session will help you get the most out of your development experience.
Elevating Code Quality with Qodana
JetBrains IDEs have always been renowned for their powerful static code analysis supporting a wide range of languages. With the release of Qodana, we are unifying that knowledge in a central code quality platform that is working at the heart of every development process – your favorite CI/CD tool.
Triggered by a commit or pull request, Qodana can generate comprehensive analysis reports (SARIF) about all discovered code quality and security issues. Qodana makes those reports easily accessible, not only to a team of developers or QA engineers but also to security managers and legal/compliance departments.
In this talk, we will explore Qodana in the context of .NET projects and look at the integrations with different CI/CD providers. Your journey towards impeccable code quality begins here, and rest assured, you won't be disappointed.
