使用.runsettings文件时代码覆盖率中不包含的异步方法

Question

每当我在不指定tested文件的情况下通过我的解决方案运行Visual 2015代码覆盖率时，我测试过的所有异步方法都包含在覆盖率结果中，并适当地着色：

​

​

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

​

​

据我所见，.runsettings文件中没有任何东西会忽略异步方法：

<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>

我是不是从我的.runsettings文件中遗漏了什么东西来完成这个工作？

原来这条线

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

导致异步方法不包含在代码覆盖率中。
