Dev Utils

Dev Utils automates the most repetitive C# development tasks directly from the Solution Explorer context menu — right-click any project, folder, file, or solution node and find the Dev Utils submenu.

Commands

Batch Extract Interfaces

Scans all public non-static classes in a project and generates IClassName interfaces in bulk. Automatically adds the interface to each class's base list and registers the new files in the project.

Generate DI Registration

Detects all IInterface → Class pairs in a project and generates a static extension class with a single IServiceCollection method containing all AddScoped<I, C>() registrations — ready to plug into your Program.cs or Startup.cs.

DI Injection Analyzer

Scans the entire solution for classes that use registered implementations via direct new ClassName() instead of constructor injection. Displays a filterable dialog with status for each candidate:

Select one or more classes and click Inject — Dev Utils will:

• Add private readonly IInterface _field;
• Add or update the constructor with the new parameter
• Replace all new ClassName(...) usages with the field reference
• Remove redundant local variable declarations
• Unwrap using (var x = new ClassName()) { } blocks

Format All Files

Formats every .cs file in a project or solution. Auto-detects the best strategy:

• No .editorconfig → runs dotnet format in the background (fast)
• .editorconfig found → uses Visual Studio's built-in formatter file by file to respect your custom rules

All operations are logged to the Dev Utils pane in the Output window.

Requirements

• Visual Studio 2022 (17.x)
• .NET Framework 4.7.2+
• dotnet format fast path requires .NET SDK installed
