Recently, on a few solutions I've been working on, the Configuration Manager dialog displays empty fields for 'Configuration' and 'Platform', and 'Build' is always unchecked. Changing values and saving the configuration doesn't fix the issue.
This does not happen on all solutions (when creating a new one, for example, this problem doesn't occur). Why could this be happening, and how do I fix it?
