[wix-devs] WixToolset.Dnc.HostGenerator errors

[Sean Hall]

You can get the files to be written to disk by adding this to the project
consuming the generator (D:\src\wix4\src\test\burn\WixToolset.WixBA):

<PropertyGroup>
    <EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
</PropertyGroup>

It seems like the generator is running twice for some reason.
