CLINQ v1.1.0.0 Released!

CLINQ v1.1 has been released. Some of you may have already downloaded some of the new builds, but here's a rundown of what the new release includes:

• Support for Continuous Aggregation. Now, in addition to being able to have your result sets automatically update themselves in response to changes in the source set as well as changes to items in the source set, you can have aggregate scalar values that continuously update in the same fashion. The following is a list of the supported aggregation types that can now be done continuously:
  • Average
  • Min
  • Max
  • Sum
  • Standard Deviation
  • Count
    
• Brand new demo application. This demo application not only shows off the power of continuous queries and WPF data binding, but also shows you how to use continuous aggregates, create your own continuous aggregates, and how to databind a WPF GUI to a continuous aggregate value.

The new demo application is called the Stock Monitor sample. It shows ticker data for both sales (price ticker) and bids and asks (quote ticker). All of this data is rolled up by continuous queries and you can see it displayed in bound fashion in the WPF GUI. More interestingly is the presence of a line graph showing the price-over-time (a custom binding based on a continuous query!) and another line on the same graph showing the VWAP over time. Continuous VWAP is a custom aggregate implemented in the demo to show you how to easily implement your own aggregation classes that fit right into the CLINQ library.

Here's a screenshot of the v1.1 Stock Monitor demo in action: 

As time permits, I will be posting more deep dives into the source code of the stock monitor demo application to show you how I built it, and how unbelievably easy it is to build stuff like this using CLINQ.

If you want the new release, head over to the CodePlex site and download it now . There are two files, one for the CLINQ library and one for the StockMonitor demo. Unzip them both as peers (beneath the same parent directory) and the StockMonitorDemo project can easily add a reference to the CLINQ project. The binaries are also included in the ZIP files.
