c# - NETSDK1061: The project was restored using Microsoft.NETCore.App version 1.0.0, but with current settings, version 2.0.9 would be used instead

Question

I'm developing a mobile app and using MS App Center for CI. Yesterday the Unit Test project failed to build in App Center with the following error. I couldn't recreate the issue on any developer machine, this error only occours in App Center.

error : NETSDK1061: The project was restored using Microsoft.NETCore.App version 1.0.0, but with current settings, version 2.0.9 would be used instead. To resolve this issue, make sure the same settings are used for restore and for subsequent operations such as build or publish. Typically this issue can occur if the RuntimeIdentifier property is set during build or publish but not during restore. For more information, see https://aka.ms/dotnet-runtime-patch-selection.

Their paid support just give the basics, clean the project, roll back my last commit ect. Has anyone come into this issue before on App Center?

Answer 1

You need to set the same publish and building runtimes

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <RuntimeFrameworkVersion>2.1.0</RuntimeFrameworkVersion> --> fix publishing issues
    <PlatformTarget>AnyCPU</PlatformTarget> --> fix publishing issues
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Update="Microsoft.NETCore.App" Version="2.1.0" /> --> fix building issues
    <ProjectReference Include="..PublicSonar.Monitor.Persistent.JsonPublicSonar.Monitor.Persistent.Json.csproj" />
  </ItemGroup>
</Project>
