SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Modernizes outdated MSBuild projects to the SDK-style format to reduce maintenance complexity and enable modern tooling.

Core Features & Use Cases

  • Guides the migration of legacy .csproj/.vbproj files to the SDK-style project format.
  • Helps identify legacy indicators such as ToolsVersion, explicit Compile Include entries, and packages.config, and recommends appropriate tooling (dotnet try-convert, Upgrade Assistant).
  • Supports incremental, safe migration with validation steps and best-practice recommendations for typical .NET projects.

Quick Start

Run the migration checklist on a sample legacy project to begin converting to SDK-style.

Frequently Asked Questions about msbuild-modernization

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

FAQPage Schema
How do I migrate legacy MSBuild projects to SDK-style format?▼

Legacy MSBuild projects are identified by indicators like ToolsVersion, explicit Compile Include entries, or packages.config. Migrating them to SDK-style reduces maintenance complexity and enables modern .NET tooling.

How do I know if my .csproj or .vbproj file is a legacy MSBuild project?▼

Legacy .csproj or .vbproj files are identified by specific indicators: a ToolsVersion attribute, explicit Compile Include entries, or the presence of a packages.config file for dependency management.

What is the best way to convert a large .NET project to SDK-style?▼

For large .NET projects, the best way to convert to SDK-style is using an incremental migration workflow. This method outlines recommended toolchains and enforces validation steps to ensure a safe transition.

Should I use dotnet try-convert or Upgrade Assistant for .NET migration?▼

Both dotnet try-convert and Upgrade Assistant are recommended for .NET migration to SDK-style. The Skill guides you through applying these tools incrementally with validation steps and follow-up actions based on your project size.

Can I incrementally migrate legacy MSBuild files without breaking my build?▼

Yes, you can incrementally migrate legacy MSBuild files safely by following an enforced validation workflow. This process uses recommended tooling to convert projects step-by-step while checking for build integrity.
