NuGet

Renovate supports upgrading dependencies in .csproj, .fsproj, and .vbproj files.

Version Support

Only SDK-style .csproj/.fsproj/.vbprojfiles are currently supported. By default, this includes:

  • .NET Core 1.0 and above
  • .NET Standard class libraries
  • Any .csproj/.fsproj/.vbproj in the SDK-style syntax

To convert your .NET Framework .csproj/.fsproj/.vbproj into an SDK-style project, one can follow the following guide.

How It Works

  1. Renovate searches in each repository for any files with a .csproj, .fsproj, or .vbproj extension
  2. Existing dependencies are extracted from <PackageReference> and <PackageVersion> tags
  3. Renovate looks up the latest version on nuget.org (or on alternate feeds) to determine if any upgrades are available
  4. If the source package includes a GitHub URL as its source, and has either a "changelog" file or uses GitHub releases, then Release Notes for each version are embedded in the generated PR

Alternate feeds

Renovate by default performs all lookups on https://api.nuget.org/v3/index.json, but it also supports alternative NuGet feeds. Alternative feeds can be specified either in a NuGet.config file within your repository (Renovate will not search outside the repository) or in Renovate configuration options:

"nuget": {
  "registryUrls": [
    "https://api.nuget.org/v3/index.json",
    "https://example1.com/nuget/",
    "https://example2.com/nuget/v3/index.json"
  ]
}

In this example we defined 3 NuGet feeds. The package resolving process uses the merge strategy to handle the 3 feeds. All feeds are checked for dependency updates, and duplicate updates are merged/joined together into a single dependency update.

Protocol versions

NuGet supports two protocol versions, v2 and v3, the NuGet client and server must use the same protocol version. Renovate as a NuGet client supports both versions and will use v2 unless the configured feed URL ends with index.json (which mirrors the behavior of the official NuGet client). If you have a v3 feed that does not match this pattern (e.g. JFrog Artifactory) you need to help Renovate by appending #protocolVersion=3 to the registry URL:

"nuget": {
  "registryUrls": [
    "http://myV3feed#protocolVersion=3"
  ]
}

Authenticated feeds

Credentials for authenticated/private feeds can be provided via host rules in the configuration options (file or command line parameter).

"hostRules": [
  {
    "hostType": "nuget",
    "matchHost": "http://example1.com/nuget",
    "username": "root",
    "password": "p4$$w0rd"
  }
]

Please note that at the moment only Basic HTTP authentication (via username and password) is supported.
