解決方法

Add a new file 'xunit.runner.json' to the test project containg the following code:

{
  "shadowCopy": false
}

Then add the following code to the test project:

<!-- Solves Problem#1 (binding error) https://github.com/Microsoft/vstest/issues/428. -->
<PropertyGroup>
    <AutoGenerateBindingRedirects>true</AutoGenerateBindingRedirects>
    <GenerateBindingRedirectsOutputType>true</GenerateBindingRedirectsOutputType>
</PropertyGroup>

<!-- Solves Problem#2 (404 when executing service calls hosted in other assemblies) -->
<!-- https://github.com/Microsoft/vstest/issues/196.-->
<ItemGroup>
    <None Update="xunit.runner.json">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
</ItemGroup>
<!-- https://github.com/NuGet/Home/issues/4412. -->
<Target Name="CopyDepsFiles" AfterTargets="Build" Condition="'$(TargetFramework)'!=''">
    <ItemGroup>
        <DepsFilePaths Include="$([System.IO.Path]::ChangeExtension('%(_ResolvedProjectReferencePaths.FullPath)', '.deps.json'))" />
    </ItemGroup>

    <Copy SourceFiles="%(DepsFilePaths.FullPath)" DestinationFolder="$(OutputPath)" Condition="Exists('%(DepsFilePaths.FullPath)')" />
</Target>
