SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps developers understand and resolve complex build errors, NuGet warnings, and analyzer diagnostics in .NET projects, preventing build failures and improving code quality.

Core Features & Use Cases

  • Error Code Interpretation: Deciphers MSBuild (MSB), C# Compiler (CS), NuGet (NU), and Analyzer (IDE, CA) error codes.
  • CI/CD Troubleshooting: Diagnoses "works locally, fails in CI" scenarios by identifying SDK differences, missing workloads, or environment discrepancies.
  • Use Case: You encounter a cryptic MSB4019 error during your build. This Skill will explain the error, identify that a required MSBuild targets file is missing, and provide steps to fix your project SDK configuration.

Quick Start

Analyze the following build output to identify the root cause of the error.

Frequently Asked Questions about dotnet-build-analysis

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix MSB4019 build errors in .NET when the imported targets file is missing?

MSB4019 build errors occur when MSBuild cannot find a required targets file, often due to incorrect project SDK configuration. You can resolve this by verifying your SDK references, restoring missing workloads, and ensuring the project file targets the correct .NET SDK version.

Why does my .NET build work locally but fail in CI/CD?

CI/CD drift happens when local and pipeline environments differ by SDK version, installed workloads, or environment variables. Diagnosing these environmental discrepancies and aligning the CI/CD pipeline SDK configuration with your local setup resolves the build failure.

How do I interpret NuGet NU and Roslyn CA analyzer warnings during a build?

NuGet NU and Roslyn CA analyzer warnings indicate package dependency issues and code quality rule violations respectively. Interpreting these error codes helps identify conflicting package versions and apply code analysis rule fixes to improve project quality.

What is the best way to troubleshoot multi-targeting build failures in MSBuild?

Troubleshooting multi-targeting MSBuild failures requires analyzing the build output for each target framework to identify SDK mismatches or missing dependencies. Analyzing the specific C# compiler and MSBuild diagnostics for each target ensures correct framework configuration.

Can I use this to diagnose C# compiler CS error codes?

Yes, you can diagnose C# compiler CS error codes by analyzing the build output. The Skill interprets these compiler errors, identifies the root syntax or semantic issue, and provides targeted steps to correct the code.

Does this Skill work without any external dependencies or plugins?

Yes, the Skill operates entirely independently without requiring external dependencies or plugins. You simply provide the .NET build output, and it interprets the MSBuild, NuGet, and Roslyn diagnostics internally.
