System.MissingMethodException with collectors on .NET 5

This is the first time trying coverlet but I cannot get it to work with either version 3.0.0 nor 1.3.0

This is my minimal test repository: https://github.com/fredrikcarlbom/coverlet/tree/main

This is the test project file from the repo - lib1.tests.csproj:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net5.0</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.8.0" />
    <PackageReference Include="xunit" Version="2.4.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.4.3">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="coverlet.collector" Version="3.0.0">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
  </ItemGroup>

</Project>

I build using build.sh:

#!/bin/bash

mkdir out
dotnet publish ./lib1.tests -c Release -o out
cd out
dotnet test lib1.tests.dll --collect:"XPlat Code Coverage"

And this is the complete output:

/mnt/c/Work/coverlet$ ./build.sh

I have the same behavior when running in powershell and WSL.

I’m going to close this because it’s a dup follow this one https://github.com/coverlet-coverage/coverlet/issues/1042

Sorry, I was focusing on that exception message.
