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.Json\PublicSonar.Monitor.Persistent.Json.csproj" />
  </ItemGroup>
</Project>

Try Adding <TargetLatestRuntimePatch>true</TargetLatestRuntimePatch>to your <PropertyGroup> tag. Example :

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <AspNetCoreHostingModel>InProcess</AspNetCoreHostingModel>
    <TargetLatestRuntimePatch>true</TargetLatestRuntimePatch>
  </PropertyGroup>

I am on Visual Studio 2019. I encountered this issue when I tried to publish my project as Self-contained for the second time.

What I did to get rid of this error was:

• Change the Deployment Mode to Framework Dependent
• Publish the project
• Change it back to Self-contained and published again

It seemed to be caused by some faulty cache that can be cleared by switching to a different deployment mode.
