Unable to load solution with .net 4 projects if configuration has '.' character in name

The error appears because the solution has a configuration name containing '.' i.e. Debug.Product and the method

ConfigurationAndPlatform::IsValidName returns false

Why is the '.' character not allowed for solution configuration? SharpDev 4.3 loads it fine btw.
