There are some breaking changes from version 3.0.2 to version 4.0.0. The most remarkable are the following:

  • The clas and interfaces DicomService, IDicomServiceProvider, IDicomCStoreProvider, IDicomCEchoProvider now are asynchronous, so the interfaces require to implement async methods now.
  • The method DicomDataset.Get behaves very different depending on parameters and types what lead to lot of confisuion. So this is now marked as obsolete and instead there are several methods GetSingleValue, GetValues, GetSequence etc. See here
  • DicomClient.WaitForAssociation is deprecated, there are now association events provided instead.
