Issue

The package identifier is found but a version within the specified dependency range cannot be found on any of the sources. The range might be specified by a package and not the user.

Solution

Edit the project file to correct the package version. Also check that the NuGet configuration identifies the package sources your expect to be using. You may need to change the requested version if this package is referenced by the project directly.

  - Found 30 version(s) in 'sourceA' [ Nearest version: '4.0.0' ]
  - Versions from sourceB were not considered

Issue

The package identifier is found but a version within the specified dependency range cannot be found on any of the sources. The range might be specified by a package and not the user.

Edit the project file to correct the package version. Check your NuGet.Config for the PackageSourceMapping configuration. The package version in question may be available on a source that is not configured.
