Visual Studio Mastery · Step 7 of 15
Code Quality & Analysis
Learn to configure Visual Studio's live analysis, .editorconfig, and warning suppression so your codebase stays clean by default.
What you’ll walk away with
- Read and act on live code analysis squiggly underlines as you type in Visual Studio
- Create and configure an .editorconfig file to enforce consistent code style across a team
- Distinguish between properly suppressing a warning (with justification) and simply ignoring it
- Apply suppression correctly so warnings are documented rather than silenced without reason
- Set up a solution from scratch with consistent formatting and clean analyzer configuration
- Establish a baseline coding standard that a team can share via source control
Questions people ask before they start
Do I need prior experience with Roslyn analyzers to take this course?
No. The course starts with live code analysis and squiggly underlines in Visual Studio, building from the basics of what the analyzer is telling you before moving into .editorconfig and suppression.
Will this teach me how to write my own custom Roslyn analyzer?
No, this course focuses on using Visual Studio's built-in live code analysis, configuring .editorconfig, and handling warning suppression responsibly — not authoring custom analyzers.
What's the difference between suppressing and ignoring a warning, and does the course actually cover that?
Yes, it's a dedicated lesson: 'Suppressing, Not Ignoring, Warnings.' You'll learn the discipline of documenting why a warning is suppressed rather than just turning it off.
Is there a hands-on project or is this all lecture?
There's a hands-on lesson, 'Hands-On: Set Up a Clean, Consistent Solution,' where you apply live analysis, .editorconfig, and suppression practices to build a consistent solution yourself.
Does this course cover team collaboration on code style, or just individual settings?
The .editorconfig lesson specifically addresses keeping style consistent across a team, not just on your own machine.
What tool does this course use?
Visual Studio. The lessons are built around its live code analysis features, squiggly underline feedback, and suppression workflow.
