NuGet Error NU1008

The following PackageReference items cannot define a value for Version: PackageName. Projects using Central Package Management must define a Version value on a PackageVersion item.

Issue

A project is configured to use NuGet Central Package Management and a <PackageReference /> item is defined which specifies a value for the Version attribute:

<ItemGroup>
  <PackageReference Include="PackageName" Version="5.1.0" />
</ItemGroup>

Alternatively, a <PackageReference /> item is defined with a child <Version /> element that has a value specified:

<ItemGroup>
  <PackageReference Include="PackageName">
    <Version>5.1.0</Version>
  </PackageReference>
</ItemGroup>

Projects configured to use Central Package Management should not define a version on <PackageReference /> items. The version should be defined in on a corresponding <PackageVersion /> item with the same identifier in Directory.Packages.props file instead.

Solution

• Remove the Version attribute or child <Version /> element from the <PackageReference /> item:

  <ItemGroup>
    <PackageReference Include="PackageName" />
  </ItemGroup>
  

• Define a <PackageVersion /> item that specifies the version in the Directory.Packages.props file with the same identifier as the <PackageReference /> item:

  <ItemGroup>
    <PackageVersion Include="PackageName" Version="5.0.1" />
  </ItemGroup>
  

Alternatively, Central Package Management allows overriding centrally defined package versions. See Overriding Package Versions for more information.
