This is the QuickFIX/n Core. This package contains the core QF/n engine, but none of the message definitions.

You most likely also need one or more message definition packages:

  • If you are using a FIX4 release, you need the corresponding QuickFIXn.FIX4* package.
  • If you are using a FIX5 release, you need the QuickFIXn.FIXT11 package and the corresponding QuickFIXn.FIX50* package

This is an official NuGet package from QuickFIXEngine.org.

Attention! The QuickFIXn.FIX4 and FIX5 message packages were renamed beginning with v1.14!

Starting with v1.14, we removed the weird extra period from the package names so that they read easier.
The packages have been renamed as follows:

  • QuickFIX.FIX4.0.{ver} becomes QuickFIX.FIX40.{ver}
  • QuickFIX.FIX4.1.{ver} becomes QuickFIX.FIX41.{ver}
  • QuickFIX.FIX4.2.{ver} becomes QuickFIX.FIX42.{ver}
  • QuickFIX.FIX4.3.{ver} becomes QuickFIX.FIX43.{ver}
  • QuickFIX.FIX4.4.{ver} becomes QuickFIX.FIX44.{ver}
  • QuickFIX.FIX5.0.{ver} becomes QuickFIX.FIX50.{ver}
  • QuickFIX.FIX5.0SP1.{ver} becomes QuickFIX.FIX50SP1.{ver}
  • QuickFIX.FIX5.0SP2.{ver} becomes QuickFIX.FIX50SP2.{ver}
  • QuickFIX.FIXT1.1.{ver} becomes QuickFIX.FIXT11.{ver}

When you update your QuickFIXn.Core nuget package, please change to the new message packages to keep the version numbers in sync!
