解决方法

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>
