NuGet QuickFix - VS Code Missing NuGet Package Installer

A Visual Studio Code extension that helps resolve missing namespaces in C# projects by searching for and installing the corresponding NuGet packages. When you encounter a CS0246 error (type or namespace not found), this extension provides a quick fix to search NuGet for a matching package and automatically install it using the .NET CLI.

Features

• Quick Fix for Missing Namespaces: Detects the CS0246 error and offers a quick fix action.
• NuGet Package Search: Uses the NuGet API to search for packages matching the missing namespace.
• Automated Installation: Once you select a package from the list, the extension runs dotnet add package to install it.

Usage

1. Open a C# File:

   Work on your C# project in VS Code.

2. Trigger the Quick Fix:

   When a missing namespace error (CS0246) occurs, a lightbulb icon appears. Click on it or press Ctrl+. (or Cmd+. on macOS) to view the available quick fixes.

3. Search for the NuGet Package:

   Select the option:

   Search for NuGet package to resolve 'YourMissingNamespace'

   The extension extracts the missing namespace from the error message and searches NuGet for relevant packages.

4. Select and Install:

   A quick pick list displays the top 5 matching NuGet packages. Select the package you wish to install, and the extension will execute the command:

   dotnet add package <SelectedPackageName>

   A notification will appear indicating that the installation is in progress.

How It Works

• Code Action Provider:
  The extension registers a CodeActionProvider for C# that listens for diagnostics with the error code CS0246. When detected, it extracts the missing namespace from the diagnostic message.

• NuGet Search:
  Using axios, the extension sends a GET request to the NuGet API endpoint:

  https://azuresearch-usnc.nuget.org/query?q=<MissingNamespace>

  The response is then filtered to show the top 5 results in a quick pick list.

• Installation Task:
  Upon selection, the extension creates and executes a VS Code task that runs the dotnet add package command in the workspace shell.

Requirements

• Visual Studio Code
• .NET SDK – Ensure that the .NET CLI is installed and available in your system PATH.
