Repro Steps & Context
Create the following project files:
ClassLibrary1.csproj
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net8.0</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Azure.Core" />
<PackageReference Include="System.ClientModel" />
</ItemGroup>
</Project>
Directory.Packages.props
<Project>
<PropertyGroup>
<ManagePackageVersionsCentrally>true</ManagePackageVersionsCentrally>
<CentralPackageTransitivePinningEnabled>true</CentralPackageTransitivePinningEnabled>
</PropertyGroup>
<ItemGroup>
<PackageVersion Include="Azure.Core" Version="1.50.0" />
<PackageVersion Include="System.ClientModel" Version="1.0.0" />
</ItemGroup>
</Project>
To workaround the problem, users have to enable to legacy dependency resolver:
<PropertyGroup>
<RestoreUseLegacyDependencyResolver>true</RestoreUseLegacyDependencyResolver>
</PropertyGroup>Verbose Logs
