Coverage of record - not 100%

[tomap]

Describe the bug
When displaying the coverage or a record, I see the line of the record declaration as not covered

To Reproduce

the coverage is produced with dotnet test in cobertura xml format via a DataCollector in the runsettings

<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">

Thanks for providing the XML. This makes it much easier.
The reason for the behavior can be found in the last <range> element:

 <range source_id="380" start_line="12" end_line="12" start_column="0" end_column="0" covered="no" />

The covered="no" attribute indicates that line 12 has not been covered.
ReportGenerator displays this information in the report, it does not analyze the source code itself.

I guess I'll investigate the producer of this report then. Thank you for the pointer and for this great piece of software!

If you use coverlet.collector you can get a Cobertura coverage file with the following command:

 dotnet test --collect:"XPlat Code Coverage"

The XML file will contain a result similar to this:

        <class name="ClassLibrary.GetRicFeedbackCommand" filename="GetRicFeedbackCommand.cs" line-rate="1" branch-rate="1" complexity="2">
          <methods>
            <method name="get_Workspacekey" signature="()" line-rate="1" branch-rate="1" complexity="1">
              <lines>
                <line number="10" hits="1" branch="False" />
              </lines>
            </method>
            <method name=".ctor" signature="(System.Guid)" line-rate="1" branch-rate="1" complexity="1">
              <lines>
                <line number="5" hits="1" branch="False" />
                <line number="6" hits="1" branch="False" />
                <line number="7" hits="1" branch="False" />
                <line number="8" hits="1" branch="False" />
              </lines>
            </method>
          </methods>
          <lines>
            <line number="10" hits="1" branch="False" />
            <line number="5" hits="1" branch="False" />
            <line number="6" hits="1" branch="False" />
            <line number="7" hits="1" branch="False" />
            <line number="8" hits="1" branch="False" />
          </lines>
        </class>

ReportGenerator will generate the following report based on this coverage file:
