Answer 1

I know the approved answer is good but I wanted to add that if you start your .runsettings file from the one suggested here (https://msdn.microsoft.com/en-us/library/jj159530.aspx) you will have a pretty good base to start with (including the proposed solution here).

Answer 2

Here's what was going on, and here's how I fixed it.

I was using a .runsettings file to exclude certain assemblies from being included in code coverage. Seems like whenever you include a .runsettings file, you must include the following configuration:

<Attributes>
    <Exclude>
        <Attribute>^System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverageAttribute$</Attribute>
    </Exclude>
</Attributes>

It doesn't seem to matter what you have in the .runsettings file - this has to be there for [ExcludeFromCodeCoverage] to work.

FYI see this article for more information on the .runsettings file: http://msdn.microsoft.com/en-us/library/jj159530.aspx
