Created Issue: Missing epsg codes in projection infos [24006]

I try to implement a projection lookup based on epsg codes. I noticed that the ProjectionInfo i get by using a lookup via ProjectionInfo.FromEpsgCode(int) always has epsg code 0.

Also ProjectionInfos via KnownCoordinateSystems.Projected don't contain epsg codes.

When i try to compare a ProjectionInfo retrieved via FromEpsgCode and KnownCoordinateSystems the ProjectionInfo.Equals() returns false because the Epsg-based ProjectionInfo has NoDefs set to false and KnownCoordinateSystems has NoDefs set to true.
