VSTS / VSTest not adhering to [ExcludeFromCodeCoverage] - unit-testing

Question

I have just recently started using Continuous Integration with VSTS and I have set up a pipeline which includes the "Visual Studio Test" Task.
Within the task, there's an option to execute a code coverage scan as part of the test.
To ensure that my code coverage only covers MY code and have a) created a .RunSettings file to include only the assemblies I generate and b) there are some parts of the code with the [ExcludeFromCodeCoverage] attribute.
Now, when execute Analyze Code Coverage from Visual Studio (2017 Enterprise, 15.7.4), everything works as I would expect, only my assembly gets analyzed and the code I have excluded is, errr, excluded.
However, when the VSTS pipeline is run, no such limitations are applied and ALL assemblies are tested and ALL code, including the specifically excluded code, which then results in a dramatic drop on the code-coverage %age.
Not sure where to go from here so hoping the S/O community can help.
Update - RunSettings file in use
<?xml version="1.0" encoding="utf-8"?>
<RunSettings>
<!-- Configurations for data collectors -->
<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">

There is an issue here: RunSettings file not used in TFS VsTest task, you can go and check the discussion about this issue.
As a workaround you can use below .RunSettings formats (add the UseVerifiableInstrumentation = False)
<?xml version="1.0" encoding="utf-8"?>
<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>
<UseVerifiableInstrumentation>False</UseVerifiableInstrumentation>
<ModulePaths>
<Include>
<ModulePath>.*\\MyProjectName.*\.dll$</ModulePath>
</Include>
<Exclude>
<ModulePath>.*Tests.dll$</ModulePath>
</Exclude>
</ModulePaths>
</CodeCoverage>
</Configuration>
</DataCollector>
</DataCollectors>
</DataCollectionRunSettings>
</RunSettings>
Just check acesiddhu's explanation:
you are using visual studio test tools installer task in your
definition. in case that task is used useverifiable property needs to
be set to false because in xcopy mode we don't GAC the above dll
'Microsoft.VisualStudio.CodeCoverage.Shim (this is a dependency which
needs to be loaded when useverifiable is set to true)
marking this property false ensures it doesn't use this particular
dll.
