I have a Java Enterprise Edition web application, a standard WAR. I want to integrate this with an existing .NET infrastructure running IIS. To be specific, I need to be able to share user sessions between the two applications in some secure manner. Is there a "standard" way of doing this? Edit: I do not need full session sharing, sorr...
While trying to get a 2008 server to connect to a sql server, I noticed a change in the 2008 IP stack that has me a bit flummoxed. I'm looking for either an OS way to override this, or a programmatic way in .NET to override this. For the sake of this argument, assume I have a web server with multiple IP addresses to server multiple site...
If I spawn a thread with ThreadPool.QueueUserWorkItem and that thread does not reference the object that is not thread safe, would it compromise that non-thread safe object? [Edit] By not thread safe object, I mean a third party interface to a programmable logic controller that has no ability to open simultaneous connections or concurre...

So f...
For instance, in VB.NET: Dim strArray(5) As String As I understand it, because this is an array, the computer will allocate contiguous memory locations for each of the 5 elements. But how much space is allocated for each of the five elements? What if I decide to put a 5MB block of text in position 2 of the array? Is it differen...
I have been going through some code seen that a colleague of mine is using 'marker classes' to control program logic (see contrived example below). It seems to work well, and the code reads really nicely, but there is just something about it that smells... namespace ConsoleApplication4983 { public class MyClass { static ...
I am working on a problem where I need to perform a lot of embarrassingly parallelizable tasks. The task is created by reading data from the database but a collection of all tasks would exceed the amount of memory on the machine so tasks have to be created, processed and disposed. I am wondering what would be a good approach to solve thi...
The Managed Extensibility Framework (MEF) and Managed AddIn Framework (MAF, aka System.AddIn) seem to accomplish very similar tasks. According to this Stack Overflow question, Is MEF a replacement for System.Addin?, you can even use both at the same time. When would you choose to use one vs. the other? Under what circumstances would yo...

I've created a Windows service in C#, installed it on a server and it is running fine. Now I want to install the same service again, but running from a different working directory, having a different config file etc. Thus, I would like to have two (or more) instances of the same service running simultaneously. Initially, this isn't pos...
