Sounds like a compelling reason to tie yourself to a third party library no-one has heard of, and therefore no-one can help you with. I've been mailing through .ENT code for years, never had a problem. Guess I checked it for myself instead of listening to what I overheard someone say in an elevator.

Hello people,
I read so many articles why not to use dynamic and how powerful it is, so it can lead to misusage and so on. But I found very few articles, that are really about practical usage, most of them are just examples of what is dynamic and quite simple usage.
I am curious to get some examples, not how it works, but where/when you really need dynamics and why?
Thanks!

I'm not up-to-date in C# 4.0, but it sounds like the devil to me.

@Richard: If you can't or don't want to answer my question, then it's easy - just don't.
I didn't ask you how to google, and if you read my question - I did NOT ask how it works or about simple examples, but about interesting solutions that somebody used about specific problem and has a valid reason to use dynamic.

I've used C# 4.0 for normal development since .NET 4.0 Beta 1 was released; and I haven't used dynamic a single time. I don't see any use for it except for talking to IronPython code.
There might some interesting other uses for dynamic in combination with custom IDynamicObject implementations; I would have to take a closer look at IDynamicObject.
In fact, the only C# 4.0 feature I use is covariance (and even that only for IEnumerable).

We have a couple of old COM components that are interacted with using late binding. We use configuration entries to determine which component to call because they have the same signatures, but they talk to different types of components, i.e. one communicates with certain hardware using TCP, while the other uses COM calls directly. The code that controls this is quite gnarly, and isn't fun to write because it requires lots of late binding work which is a complete PITA in .NET.
With dynamic, we can replace this code with a simple class that takes this pain away. So far, it's the only use I can find for using dynamic.

Hey guy,
When to use c# preset attributes in general, like
[MethodImpl(MethodImplOptions.Synchronized)] and is it possible to not use it at all??
Any help appreciated, thanks in advance.

Use them when you want to specify something that is specified by attributes, and don't use them when you are happy with the default value.

could you give an example!!!!!
|
|
|
|

For your particular example, never use MethodImplOptions.Synchronized
It locks on the Type for static methods and this for instance methods - both bad practice.

Thanks for your nice reply, actually it benefits me a lot, but that's not what I need to know. What I was asking about was "When it become a necessity to use attributes in your code???"
Thanks a lot

Hi!
I have implimented Client Application Services in my Windows Application. I have a DAL and a Web Application as well. I am using ASP.NET Membership framework to enable my windows application to login a user against the same database that he uses to logon to the website.
The problem is that I can logon with a username and password on the website without any problem but when I try logging on to the windows app I cant authenticate.
I checked my connectionstring, membershipprovider, roleprovider etc but everything is fine. When I logon using my ID I can logon to both windows and web but when I create a new id using the ASP.NET Configuration tool I cannot logon to the windows app. I can logon to the website.
Any thoughts and/or ideas??

You told that your connectionstring,membershipprovider,roleprovider etc. are fine and when you are creating new account, it can't be authenticate..
This might because your new account is still deactivated..so checkout in your database, whether that user is active or not??

This is a SQL question and we have a SQL forum. If you bother to ask there, try to ask a question that actually explains what you want to do, what you've tried and where you are stuck.

Respected Sir's/Friends, i am building a project called a VideoBroadcaster, in this project i have to build a server and client. when the admin user will play a video file on the server same file should be played at the client machine.
Suggest me how to achieve this.
remoting? tcpchannel ? httpchannel or socket ? which one will be better.
we will need serialization?
Kindly help me thanks in advance

So, an admin starts a video on the server, it HAS to play on the server, and also be visible on the client ? They have to be in synch ? The admin can pause the video and it pauses on the client ? How much do you need them to play on the server, and how much control should the server have ?

Thanks for reply
Admin will have the full control and in admin module we will have a video player type UI, in which he can play/pause/stop and that should be visible on the client machine

OK, well, that does make things more messy. If it's not a web based UI ( which I assume by what forum you're in ), then I'd imagine you'd send the videos down to the client, and you'd use a connection ( perhaps through WCF ? ), to send messages to all the clients telling them when to pause, when to play, and from time to time to tell them where the admin video is at so they stay in synch.
