.NET Core 3.1 - Could not load file or assembly System.Runtime, Version=4.2.2.0

.NET Core 3.1 console app generates error during build -

System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime, Version=4.2.2.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

But it works on .NET Core 3.0 version.

I'm using Microsoft.Orleans. This is csproj - 

    <Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Orleans.Core" Version="3.0.2" />
    <PackageReference Include="Microsoft.Orleans.OrleansCodeGenerator.Build" Version="3.0.2">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

  1. Load your project by double clicking on the "NameOfYourFile.csproj"
  2. In the menu bar, click Project => properties of "NameOfYourFile. Choose "Application" and select a valid Framework Target (the newest in the list).
  3. Rebuil, it should work.

Make sure you load your project properly (not just the folder which contains the project). In my case, instead of loading the .csproj file, I loaded just the folder which contains the whole project. What I did then, reloaded and clicked the .csproj file explicitly, then it came back to normal.

In my case Nischal Nigam's solution didn't worked out, so what I did, I updated the package Microsoft.NET.Sdk.Functions from version 1.0... to 3.0.11 and after that it started working just fine.

I am using Microsoft Visual Studio - Version 16.4.5

Go to the following location and open the devenv.exe.config file in a text editor:

C:\Users\<username>\AppData\Local\Microsoft\VisualStudio\16.0_1832c881\devenv.exe.config

Paste this binding in <configuration> -> <runtime> -> <assemblyBinding>

<dependentAssembly>
  <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
  <bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="4.0.0.0"/>
</dependentAssembly>

After this, save the file and restart Visual Studio.

ReubenBond helped me with solution. I used Microsoft.Orleans.CodeGenerator.MSBuild package instead of Microsoft.Orleans.OrleansCodeGenerator.Build.
