NuGet Centrally Manager Packages - NU1604 Error on build with dotnet build

Question

I am trying out the Centrally Managed Packages feature in NuGet and keep getting the following error in all of my projects:

NU1604: Project dependency Ardalis.SmartEnum does not contain an inclusive lower bound. Include a lower bound in the dependency version to ensure consistent restore results.

I have the following defined in the .csproj

<Project Sdk="Microsoft.NET.Sdk">
    <ItemGroup>
        <PackageReference Include="Ardalis.SmartEnum" />
    </ItemGroup>
</Project>

and the following Directory.Build.props defined in the root folder beside my .sln file

<Project>
    <PropertyGroup>
        <TargetFramework>net7.0</TargetFramework>
        <Nullable>enable</Nullable>
        <ImplicitUsings>enable</ImplicitUsings>
        <TreatWarningsAsErrors>true</TreatWarningsAsErrors>
    </PropertyGroup>

    <PropertyGroup>
        <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
    </PropertyGroup>

    <ItemGroup>
        <PackageVersion Include="Ardalis.SmartEnum" Version="2.1.0" />
    </ItemGroup>
</Project>

An interesting thing is that I am able to get the project to build in Rider, but not with the dotnet build command. Both when running in the root folder and in the project folder. I have tried dotnet clean on both the solution and the project.

For clarity the file structure is:

root/
├─ Directory.Build.props
├─ MySolution.sln
├─ src/
│  ├─ ProjectFolder/
│  │  ├─ ProjectFolder.csproj

What am I missing here?

Answer 1

I was missing a key piece of information.

Centrally managed packages should not be defined in Directory.Build.props.

They should be defined in Directory.Packages.props

Directory.Packages.props

<Project>
    <PropertyGroup>
        <ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
    </PropertyGroup>

    <ItemGroup>
        <PackageVersion Include="Ardalis.SmartEnum" Version="2.1.0" />
    </ItemGroup>
</Project>
