Composite UI Application Block - Thread SafeDoes anyone have any input on setting up my CAB application so that the
application is thread safe, and cached appropiately? I read that this can be managed through Services, and dynamic injection. On the contrary, I was told that this can be handled using Enterprise Library cached application block. Last, but not least, i read you can implement this at the class level, creating immutable classes, and caching them accordingly. Any suggestions would be greatly appreciated? All UI operations must be carried out on the UI thread. Therefore you
still need to make the distinction in CAB whether the operation is a graphical one or not. A service dependency for example may work well on some other thread but a UI operation will not. CAB only connects up the various parts of the application. Those parts all need to respect the basic principals. -- Show quoteHide quoteBob Powell [MVP] Visual C#, System.Drawing Ramuseco Limited .NET consulting http://www.ramuseco.com Find great Windows Forms articles in Windows Forms Tips and Tricks http://www.bobpowell.net/tipstricks.htm Answer those GDI+ questions with the GDI+ FAQ http://www.bobpowell.net/faqmain.htm All new articles provide code in C# and VB.NET.

description: I would like to pull data from a data layer, and keep that information cached so that you don't have to make repeated calls to the data base. From the little research I have done so far, and from what you described to me, it seems possible to keep the information in the ui thread, and use CAB's service to pull data from the data layer, populate a view or module, simply use that instance in a workitem, where it can be passed around accordingly. However, if this can't be done at the ui level, then i thought about using the cached application block provider from enterprise library at the data access layer.. Do you see anything wrong with this? THanks..
