For managed projects, you can control their build order via the IDE. Right-click on the project in the Solution Explorer, and select Project Dependencies.
This will pop up the Project Dependencies dialog.
Now you can say who depends on whom, but if you try to create a circular dependency, we’ll catch ya!
Looks like someone forgot the period in the sentence. =)
You can also do the same from Solution Properties, but you can’t view the build order. So maybe that justifies tomorrow’s tip.
