Response from our Developers:

The above error messages are disconcerting because they look like there’s something horribly wrong with your project. 
These messages don’t mean you have a problem. They are a result of how Microsoft handles WPF behind the scenes.
You can safely ignore them.

If you want to remove them, you can edit your App.config file (located in your project folder) and add the following lines below to the configuration section:

<configuration>
  <system.diagnostics>
    <sources>
      <source name="System.Windows.Data" switchName="SourceSwitch">
        <listeners>
          <remove name="Default" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>
</configuration>

As a result of the above finding no patch will be provided.
