Test Run fails with "An exception occurred while invoking executor 'executor://mstestadapter/v2': Type ... is not marked as serializable."

解决方案：

• Mark type as Serializable.
• Don't add the type to CallContext.
• Set DisableAppDomain value to true in runsettings (supported by MSTest v2, NUnit and XUnit).

       Using a runsettings file User can specify a runsettings file to configure test run. For example:

• > vstest.console.exe --settings:test.runsettings test.dll
• > dotnet test -s test.runsettings

3. Using command line runsettings parameters Various elements of a runsettings file can also specified as command line parameters directly. For example, consider following runsettings:

<RunSettings>
    <RunConfiguration>
        <DisableAppDomain>True</DisableAppDomain>
    </RunConfiguration>
</RunSettings>
