Manage NuGet packages in .NET projects/solutions. Use this skill when adding, removing, or updating NuGet package versions. It enforces using `dotnet` CLI for package management and provides strict procedures for direct file edits only when updating versions.

NuGet Manager Overview This skill ensures consistent and safe management of NuGet packages across .NET projects. It prioritizes using the dotnet CLI to maintain project integrity and enforces a strict verification and restoration workflow for version updates. Prerequisites .NET SDK installed (typically .NET 8.0 SDK or later, or a version compatible with the target solution). dotnet CLI available on your PATH . jq (JSON processor) OR PowerShell (for version verification using dotnet package search ). Core Rules 1. NEVER directly edit .csproj , .props , or Directory.Packages.props files to add or remove packages. Always use dotnet add package and dotnet remove package commands. 2. DIRECT EDITING is ONLY permitted for changing versions of existing packages. 3. VERSION UPDATES must follow the mandatory workflow: Verify the target version exists on NuGet. Determine if versions are managed per project ( .csproj ) or centrally ( Directory.Packages.props ). Update the version string in the appropriate file. Immediately run dotnet restore to verify compatibility. Workflows Adding a Package Use dotnet add [<PROJECT ] package <PACKAGE NAME [ version <VERSION ] . Example: dotnet add src/MyProject/MyProject.csproj package Newtonsoft.Json Removing a Package Use dotnet remove [<PROJECT ] package <PACKAGE NAME . Example: dotnet remove src/MyProject/MyProject.csproj package Newtonsoft.Json Updating Package Versions When updating a version, follow these steps: 1. Verify Version Existence : Check if the version exists using the dotnet package search command with exact match and JSON formatting. Using jq : dotnet package search <PACKAGE NAME exact match format json jq e '.searchResult[].packages[] select(.version == "<VERSION ")' Using PowerShell: (dotnet package search <PACKAGE NAME exact match format json ConvertFrom Json).searchResult.packages Where Object { $ .version eq "<VERSION " } 2. Determine Version Management : Search for Directory.Packages.props in the solution root. If present, versions should be managed there via <PackageVersion Include="Package.Name" Version="1.2.3" / . If absent, check individual .csproj files for <PackageReference Include="Package.Name" Version="1.2.3" / . 3. Apply Changes : Modify the identified file with the new version string. 4. Verify Stability : Run dotnet restore on the project or solution. If errors occur, revert the change and investigate. Examples User: "Add Serilog to the WebApi project" Action : Execute dotnet add src/WebApi/WebApi.csproj package Serilog . User: "Update Newtonsoft.Json to 13.0.3 in the whole solution" Action : 1. Verify 13.0.3 exists: dotnet package search Newtonsoft.Json exact match format json (and parse output to confirm "13.0.3" is present). 2. Find where it's defined (e.g., Directory.Packages.props ). 3. Edit the file to update the version. 4. Run dotnet restore .
