What's New

We've added the System.ServiceModel.UnixDomainSocket package (PR #5172) to provide support for using unix domain sockets with WCF Client. This provides an alternative to NetNamedPipe and works on all supported platforms. This was contributed by @birojnayak from AWS.

Bug Fixes:

-Use LINQ Expressions for implementation of default IOperationInvoker. If there are any unexpected compatibility issues, the prior implementation can be used by setting the AppContext switch System.ServiceModel.Dispatcher.UseLegacyInvokeDelegate to true, contributed by @g7ed6e (PR #5298).

• Fixed issue with unhandled exception when an idle connection pool socket is closed (PR #5342).
• Fixed race condition in NetTcp which can cause a failure on CPU's with a weaker memory model (PR #5343).
