• Visual Studio 2008 (Pre-release) WCF call fails sometime in CAB application

I have checked the WCF log file and found that before the exception was raised, the message was already received by the client side; but for some reason, the message was not processed until timeout. If I not to use CAB, it seems everything works fine. I think a dead lock could be generated by ObjectBuilder, which is the main part of all the application blocks. I have wrote a small test program which has the exactly same problem. I cannot locate the problem precisely ...Show All

One, I need some interesting formatting on the text, second, I wanted a gradient background on the header cells) but it's not trivial, because th ...Show All
