Changeset 11285 for trunk/sources/HeuristicLab.Problems.Instances

Message:

#2225
The ProblemInstanceProvider is now contravariant. Therefore the ProblemInstanceManager discovers all derivations of InstanceProvider<IVRPData>.

Note that there was a problem with covariant InstanceConsumers with the ProblemInstanceProviderView in the past (#1981).
Due to the fixes from #2110 this problem should not occur anymore.
