Use packageRules to control the behavior of the NuGet package manager.

The NuGet package manager supports these SDK-style files and formats:

• .csproj
• .fsproj
• .vbproj
• .props
• .targets
• global.json
• dotnet-tools.json

.NET Core projects are supported by default.

For Renovate to work with .NET Framework projects, you need to update these files so they match the new SDK-style format:

• .csproj
• .fsproj
• .vbproj
• .props
• .targets

Disabling updates for pinned versions

In Nuget, when you use versions like Version="1.2.3" then it means "1.2.3 or greater, up to v2" When you use versions like Version="[1.2.3]" then it means "exactly 1.2.3".

If you would like Renovate to disable updating of exact versions (warning: you might end up years out of date and not realize it) then here is an example configuration to achieve that:

{
  "packageRules": [
    {
      "description": "Skip pinned versions",
      "matchManagers": ["nuget"],
      "matchCurrentValue": "/^\\[[^,]+\\]$/",
      "enabled": false
    }
  ]
}
