WCF Contrib is a library with infrastructure implementations for client and service communications using WCF technology.
The project contains useful components assembled from long-term business applications development and best practices.
- July 3, 2010 - WcfContrib v2.1.1
This release adds core optimizations and internal fixes to the infrastructure.
There are no breaking changes from the last version, only internal improvements.
In previous versions you may have encountered synchronization related errors such as recursive write/read locking.
These issues were resolved and you should no longer experience that.
This release is highly recommended over previous versions, make sure you use this one.
- April 16, 2010 - .NET 4.0 - WcfContrib v2.1
The same version released on March 7th had been compiled for .NET 4.0 and is now available for download -
- March 7, 2010 - WcfContrib v2.1 Final March 07
A new release had been published - WCF Contrib v2.1 Mar07.
This release is the final version of v2.1 Beta that was published on February 10th, so you can check the entire updates made from v2.0 further below.
You can distinguish between this release and the v2.1 Beta Feb10 by checking the assembly
version, in this release it was incremented to v220.127.116.11.
Changes from v2.1 Feb10 Beta
There is a one small change which is a breaking change for those who used the asynchronous invocation pattern using the "InvokeChannelAsync" or "InvokeAsync". (protected methods of ClientChannel)
This is a seldom used pattern so the chances of that affecting you are pretty minimal.
The change is very simple, instead of working with AsyncServiceInvokeCallback in these methods, it gets the general AsyncCallback which it then calls by passing it a ChannelInvokeAsyncResult which contains all the information needed.
- February 10, 2010
- A new documentation was added with answers to frequently asked questions.
- February 8, 2010
A section describing how to customize the output caching module was added,
Client Channel Output Caching
- February 6, 2010
- February 5, 2010 - WcfContrib v2.1 Beta Feb10
A new release was published. It has been tested and it is stable. However, there were some core optimizations so this is considered to be a small test-run to make sure it is alright before tagging it as a stable release.
Please provide feedback, your input is important.
Changes from last version
Updated Showcases from last time
- New Output Caching module for Client Channel (read more).
Useful feature, be sure to check it out in the showcases
- New behavior attributes and extension elements (ActivationContextInitializerAttribute, ActivationContextExtensionBehaviorElement, ErrorContextHandlerExtensionElement)
- A userful commonly-needed synchronized (thread-safe) dictionary was added: SynchronizedDictionary
- Internal Optimizations and Mode Fixes. (Sequential channel management option work with asynchronous operations now)
