• C# 4: Real-World Example of Dynamic Types

  - by routeNpingme

  I think I have my brain halfway wrapped around the Dynamic Types concept in C# 4, but can't for the life of me figure out a scenario where I'd actually want to use it. I'm sure there are many, but I'm just having trouble making the connection as to how I could engineer a solution that is better solved with dynamics as opposed to interfaces, dependency injection, etc. So, what's a real-world application scenario where dynamic type usage is appropriate?

• sample project of how to use Office.WebUI.Ribbon

  - by devn

  This is a trouble-some rather than an issue. I am searching for a free asp.net ribbon control and I have found this one: http://www.officewebui.com/ I can download the source code of the control. However, there is no sample asp.net project using that Ribbon control. I wonder if there is a sample project to show how to use that control in asp.net. That would be great if you share it. Thanks in advance.

• How can I assign more than one ValueProvider to ModelBindingContext when testing a custom model bind

  - by Byron Sommardahl

  I have a custom model binder that uses data from session, tempdata, and form collection (hypothetically, of course!). When testing my model binder, need to create a ModelBindingContext with a ValueProvider. Trouble is, I can't see how I can have one ValueProvider that serves multiple value provider types. Any words of wisdom? ValidModelBindingContext = new ModelBindingContext { ModelName = "SomeModel", ValueProvider = ValidFormValueCollection };

• Do I need to compile my solution with VS2010 in order to benefit from .NET 4.0 new Code Access Secur

  - by leo

  Hello, I currently develop an application in C# with framework .NET 3.5 SP1. In my app, I have satellite assemblies which are not in the same folder as the exe, and that causes me some trouble with FullTrust, as explained here. In order to solve that problem, I wish to use .NET 4.0 whose Code Access Security Policy should allow my satellite assemblies to be FullyTrusted. So my question is: is just installing the framework enough, or do I need to rebuild the solution with VS2010? Thanks

• SmartGWT alternatives

  - by Roger

  I have been using SmartGWT but have run into trouble mixing SmartGWT with other frameworks such as Wicket. Infact it has been a bit of a disaster and I regret going with it in the first place. I do not want this question to turn into any type of flame war, so therefore would just like people to list alternatives and their experience with those alternatives.

  It may be a bit confusing, but... Let's say I have a vector type in a class to store objects, something like vector, and I have methods on my class that will later return Operators from this vector. Now if any of my methods receives an Operator, will I have any trouble to insert it directly into the vector? Or should I use the copy constructor to create a new Operator and put this new one on the vector?
