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
Open a C# File:
Work on your C# project in VS Code.
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.
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.
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:
