What is DotNET Build Buddy?

DotNET Build Buddy is a powerful VS Code extension designed to eliminate the tedious manual work of managing .NET project files. It automatically generates and maintains your .sln, .csproj, .fsproj, and .vbproj files while providing intelligent NuGet package compatibility checking.
The extension activates automatically when it detects .NET-related files in your workspace - no manual configuration needed to get started.

​
Key Features

Automatic Project File Generation

Creates appropriate project files based on your source files - no more manual XML editing

Solution File Management

Generates and maintains .sln files that include all discovered projects automatically

Real-time File Monitoring

Watches for file changes and automatically updates project files when source files are added, modified, or deleted

NuGet Compatibility Checking

Verifies package compatibility with your target framework and suggests correct versions or alternatives

​
How It Works

DotNET Build Buddy follows a simple workflow:
1

Activation

The extension activates when it detects .NET-related files (.cs, .fs, .vb, or project files) in your workspace
2

Monitoring

It continuously monitors changes to source files and project files in real-time
3

Auto-Update

When changes are detected, it automatically updates the corresponding project files based on your directory structure
4

Compatibility Checking

NuGet packages are checked for compatibility with your target framework, and suggestions appear inline in your project files

​
Multi-Language Support

The extension supports all major .NET languages:
  • C# - .cs files generate .csproj projects
  • F# - .fs files generate .fsproj projects
  • VB.NET - .vb files generate .vbproj projects
Files are automatically grouped by directory structure, creating separate projects when appropriate for better organization.

​
Intelligent NuGet Features

DotNET Build Buddy goes beyond basic project management with advanced NuGet capabilities:

​
Real-time Compatibility Checks

The extension fetches package information from the NuGet.org API to verify compatibility with your target framework. You’ll see:
  • Red squiggly lines on incompatible packages (errors)
  • Yellow squiggly lines on version mismatches (warnings)
  • Hover tooltips with detailed information and suggestions

​
Smart Suggestions

When compatibility issues are detected, you get actionable recommendations: 
❌ EntityFramework: Package is not compatible with net8.0
  🔄 Alternative: Microsoft.EntityFrameworkCore (8.0.0) 
  📝 Recommendation: Modern Entity Framework Core for .NET Core/.NET 5+

​
Framework Upgrade Recommendations

The extension analyzes your dependencies and suggests framework upgrades when beneficial: 
💡 Project.csproj: Consider upgrading from netcoreapp3.1 to net8.0. 
   All packages support net8.0

​
Transitive Dependency Checking

Not only are direct dependencies verified, but the extension also checks compatibility of transitive dependencies (dependencies of dependencies) to prevent runtime surprises.
