I'm very interested in using 4.0 framework and also the Entity Framework 4.0. Currently .net 4.0 is in CTP and I'm EF 4.0 is in CTP Preview. I will not be coding for a few more months, but i'm not so sure that either .net 4.0 or EF 4.0 will be RTM by then.
My questions:
1) Regarding Microsoft Products, is CTP usually stable enough ...

I'm trying to demonstrate invariants in Code Contracts, and I thought I'd give an example of a sorted list of strings. It maintains an array internally, with spare space for additions etc - just like List<T>, basically. When it needs to add an item, it inserts it into the array, etc. I figured I had three invariants:
The count must be ...

Hey,
I wanted to play around with using a MemoryMappedFile to access an existing binary file. If this even at all possible or am I a crazy person?
The idea would be to map the existing binary file directly to memory for some preferably higher-speed operations. Or to atleast see how these things worked.
using System.IO.MemoryMa...
Hi,
I'm trying to deploy a .NET 4.0 project with Visual Studio 2010 using MSDeploy; however when I right-click on the project, what shows up is the legacy context menu for Visual Studio 2008 ('Publish Website', 'Build Website' etc.) in lieu of the VS 2010 context menu ('Publish', 'Build' etc.). I'm running Windows Vista and IIS 7.0.

I'm writing a small visualization tool in wpf, the idea is that average users can create interesting visualizations without being programming wizards.
I have a controller class that has methods like StartPath(double x, double y) and LineTo(x,y) CurveTo(...) etc.
The idea is that a user can type these commands into a textbox and have it...
For example this article introduces them.
What is the benefit?
Static analysis seems cool but at the same time it would prevent the ability to pass null as a parameter in unit test. (if you followed the example in the article that is)
While on the topic of unit testing - given how things are now surely there is no point for code cont...

I am preparing to start on a new short-term contract (1-2 months) that involves replacing an Access application by moving it to ASP.NET and SQL Server.

I can recall back when working with MFC you could support multiple versions of the MFC framework by checking the _MFC_VER macro.

I've created a custom activity in a .NET 4.0 beta 1 WF project. It's defined as:
public class GetCurrentUserMailAddress : CodeActivity<string>

context.SetValue(Result, up.EmailAddress);
But now I'm struggling ...
I'm seeing different behavior between using .Equals and == between two of .NET 4.0's new Tuple<> instances. If I have overridden Equals on the object in the Tuple<> and call .Equals on the Tuples the override of Equals will be called. If I use == on the Tuples the override of Equals is not called. Is that by design and does it make sense...

I've been playing with Code Contracts on VS2008 (http://msdn.microsoft.com/en-us/devlabs/dd491992.aspx).
They surely are nice and provide a solid alternative to if-then-throw checks inside methods.
Nonetheless I've been hoping that they could satisfy the need that I strongly feel for non-nullable reference types.
Alas, from what I could...
