Message:

#3026:

• removed type extension for type comparison (was a complicated comparison, which should not be a public extension method for Type)
  • comparison is now located (as private method) in JsonItemConverter
  • also simplified it a lot (did some tests to measure the relevance of specific checks -> last check got completely removed)

Location:

Files:

• Extensions/TypeExtensions.cs (deleted)
• HeuristicLab.JsonInterface.csproj (modified) (3 diffs)
• JsonItemConverter.cs (modified) (2 diffs)
