Hi, I am attempting to model a worklfow using a "WCF Workflow Service" in .net / vs 2010 that needs to handle out of order execution gracefully (but not allow it - if thath makes sense!?) For example I have 2 receive activities one called Initialize and the other called GetValue inside a FlowChart. In most cases Initialize should be c...
We have several .NET applications developed in .NET 3.5 (Windows services, web applications, and WCF services) in different servers. I'd like to migrate to .NET 4.0 and use VS.NET 2010. Does VS.NET 2010 compiles to .NET 3.5 to avoid full simultaneous migration, being able to stop using VS.NET 2008 but maintaining some applications in ...

However, clients have shown their interest in migrating the developed payroll application in Microsoft Visual Studio 2008 (.Net 3.5) to Microsoft V...
Hi, I'm using .NET 4's System.Numerics.BigInteger structure. I need to calculate the square (x2) of very large numbers - millions of decimal digits. If x is a BigInteger, What is the time complexity of: x*x; or BigInteger.Pow(x,2); ? How can multiply such big numbers in the fastest way using .NET 4 BigInteger? Is there an imple...

Hi there, We're trying to migrate a .Net 3.5 solution into .Net 4.0, but are experiencing complications with the testing frameworks that can operate using an assembly that is built using version 4.0 of the .Net Framework. Previously, we used NUnit 2.4.3.0 and NCover 1.5.8.0 within our NAnt scripts, but NUnit 2.4.3.0 doesn't like .Net 4...
My application compiled in .NET 4 seems to be performing really slow compared to .NET 3.5. When I did the performance analysis, I found out that the System.Math libraries in VS2010/.NET 4 have slowed down considerably. Any explanation to this? Has anyone else come across this or am I the only one seeing this? UPDATE: My sample code l...

MSDN said that BlockingCollection.Take call blocks if there is no elements in it. Does it mean the thread will yield the timeslice and go to the waiting threads queue? If yes does it mean that the thread will change its state to Ready once the blocking collection received an item and then will be scheduled to next timeslice as per usual...

According to this article, Visual Studio 2010 no longer supports SQL Server 2000. However, it's a bit less clear on whether the runtime (and things like ASP.net 4.0, Linq2SQL and EF) will work with it. It seems that only the design-time features require SQL Server 2005 or greater according to that article. I have a project that requir...
I have time-critical piece of code in my app. I made the thread which runs it Highest priority - that's the most I could do. Is there any suggestions on how to make part of the code run in this thread to be interrupted as few times as possible (less context switch occurred) ? The code is not complicated. I replaced all the method calls...

In Russinovich book it says that thread (NOTE: this is about OS thread) will need dispatching (scheduling) if it a) became ready b) ended its timeslice, yields or blocks. I have a managed thread in my C# real-time app for which is very important to achieve as fewer context switches as possible. This thread has Highest priority and the ...
