c# - 使用 .runsettings 文件时，代码覆盖率中不包含异步方法

Question

每当我在没有指定测试设置文件的情况下对我的解决方案运行 Visual Studio 2015 代码覆盖率时，我测试过的所有异步方法都会包含在覆盖率结果中并适当着色:

但是，当我包含一个 .runsettings 文件时，异步方法不再包含在 Coverage 结果中并且保持未着色:

据我所知，.runsettings 文件中没有任何内容会忽略异步方法:

<RunSettings>
  <DataCollectionRunSettings>
    <DataCollectors>
      <DataCollector friendlyName="Code Coverage" uri="datacollector://Microsoft/CodeCoverage/2.0" assemblyQualifiedName="Microsoft.VisualStudio.Coverage.DynamicCoverageDataCollector, Microsoft.VisualStudio.TraceCollector, Version=11.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a">
        <Configuration>
          <CodeCoverage>

            <!-- Match assembly file paths: -->
            <ModulePaths>
              <Exclude>
                <ModulePath>.*xunit.*</ModulePath>
              </Exclude>
            </ModulePaths>
            <!-- Match attributes on any code element: -->
            <Attributes>
              <Exclude>
                <!-- Don't forget "Attribute" at the end of the name -->

                <Attribute>^System\.Diagnostics\.DebuggerHiddenAttribute$</Attribute>
                <Attribute>^System\.Diagnostics\.DebuggerNonUserCodeAttribute$</Attribute>
                <Attribute>^System\.Runtime\.CompilerServices.CompilerGeneratedAttribute$</Attribute>
                <Attribute>^System\.CodeDom\.Compiler.GeneratedCodeAttribute$</Attribute>
                <Attribute>^System\.Diagnostics\.CodeAnalysis.ExcludeFromCodeCoverageAttribute$</Attribute>
              </Exclude>
            </Attributes>

            <!-- We recommend you do not change the following values: -->
            <UseVerifiableInstrumentation>True</UseVerifiableInstrumentation>
            <AllowLowIntegrityProcesses>True</AllowLowIntegrityProcesses>
            <CollectFromChildProcesses>True</CollectFromChildProcesses>
            <CollectAspDotNet>False</CollectAspDotNet>

          </CodeCoverage>
        </Configuration>
      </DataCollector>
    </DataCollectors>
  </DataCollectionRunSettings>
</RunSettings>

我是否缺少我的 .runsettings 文件中的某些内容以使其正常工作？

Answer 1

结果是行

<Attribute>^System\.Runtime\.CompilerServices.CompilerGeneratedAttribute$</Attribute>

导致异步方法未包含在代码覆盖范围内。
