Changed

SqlDecimal type workarounds conversions

What Changed:

• Changed how SqlDecimal type workarounds perform conversions to meet
  compliance policies.
  (#​3467)

Who Benefits:

• Microsoft products must not use undocumented APIs on other Microsoft products.
  This change removes calls to undocumented APIs and replaces them with
  compliant API use.

Impact:

• These changes impose an observed 5% decrease in performance on .NET Framework.

SqlVector API improvements

What Changed:

• Several changes were made to the SqlVector API published in the
  6.1.0-preview2 release
  (#​3472):
  • The SqlVector class was changed to a readonly struct.
  • The null value constructor was changed to a static CreateNull() method.
  • The Size property was removed.

Who Benefits:

• SqlVector instances gain the efficiencies of struct handling.

Impact:

• Early-adopter applications may require updates if they rely on the old APIs
  and any class-specific behaviour.
