Azure DevOpsで実行すると、xUnitテストが失敗する

さまざまなAzureDevOps CI/DI機能を試すための非常に単純なテストプロジェクトを作成しています。このプロジェクトには、ASP.NET CoreWebサイトプロジェクトとxUnitユニットテストプロジェクトを使用したソリューションが含まれています。単体テストはローカルマシンで正しく実行されます（VisualStudioランナーとdotnet testでテストされていますが、Azureビルドで動作させることはできません。

Azureでの単体テストステップの出力は次のとおりです。

Task         : Visual Studio Test
Description  : Run unit and functional tests (Selenium, Appium, Coded UI test, etc.) using the Visual Studio Test (VsTest) runner. Test frameworks that have a Visual Studio test adapter such as MsTest, xUnit, NUnit, Chutzpah (for JavaScript tests using QUnit, Mocha and Jasmine), etc. can be run. Tests can be distributed on multiple agents using this task (version 2).

不足しているjsonファイルがどのようにあるのか理解できていません。エラーはMicrosoft.NET.Test.Sdkをインストールすることを示唆していますが、プロジェクトファイルで参照されています：

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>

    <IsPackable>false</IsPackable>

    <RootNamespace>ContosoUniversity</RootNamespace>
  </PropertyGroup>

だから私が欠けているものについてのヒントをいただければ幸いです。

@Shtongのおかげで、xunitパイプラインビルドを修正することができました。これは将来の参考のために私のYAMLファイルです：
