Always use 'Configuration' property

[Nirmal4G]

If we set ConfigurationName to something else, the debug builds break!

Talked about this in team triage today. @Forgind figured out that it's likely a breaking change.

Consider a case where you have a custom configuration that is "like debug". For instance, our own Debug-MONO configuration. You can then set ConfigurationName to Debug for that to get the default "like Debug behavior".

We just took a quick look through our internal history and ConfigurationName was introduced just before MSBuild (1.0!) RTM. The commit notes aren't super helpful, but we expect it was because of that case.

Thanks for trying to clean this up! But I don't think we can take this.

This should be in the docs. I was using it for that exact purpose but other way around. Thanks for clarifying.
