dxFeed .Net API 8.5.0

• [DXFC-266] Improved functioning of CandleDataConnection and TimeAndSaleDataConnection in Blazor\UI applications.
• [DXFC-267] Fixed a bug with possible call of callbacks/delegates from the native library when the memory of subscriptions/connections objects is cleared by the GC
• [DXFC-268] Fixed a bug with AccessViolationException when the user called Dispose of the subscription after Dispose of the connection.
• [DXFC-271] Fixed a bug with incorrect UTC timezone when requesting data from the CandleWebService
• [DXFC-269] .NET API common enhancements
  • The dxf_order_view_sample example now uses one symbol and source.
  • All native event fields now have public setters.
  • All native events now have public copy constructors and default constructors.
  • If no date\time is specified, then dxf_events_sample is not subscribed to time series.
  • dxf_ipf_connect_sample: added an ability to set bearer token
  • Added XML documentation for all public\protected API entities (interfaces, methods, classes etc.)
  • The DayUtil class is now public
• [Attention] Some architectural issues have been discovered that impose restrictions on the use of connection objects.
  It is not recommended to use multiple connections in parallel in the same process. This applies to objects created with
  the NativeConnection constructor and the DXEndpoint.Connect, TimeAndSaleDataConnection.GetTimeAndSaleData, CandleDataConnection.GetCandleData methods.
  This limitation will be lifted after API design changes.
