looking for a small sample. i search google a bit but found no example. thanks

Might I makes a suggestion: Amazon: Entity Framework[^].
Serisouly, you're not going to learn this stuff by bombarding the forums with questions. You're going to miss a ton of information that ties all this stuff together.

OR
Return 1
just tell me how to read the single value return by store proc with EF code first. looking for a small sample code. i search google a bit but found no example. thanks

Really?[^]. They probably aren't all relevant but Google thinks there are 456,000 items that match.

We've run into a problem where we're getting a Task Canceled Exception. It seems to occur when
code inside a App.Current.Dispatcher.Invoke... gets executed AFTER App.Current.Shutdown is called.
I really don't want to have to check for the app being shutdown every time I do App.Current.Dispatcher.Invoke.
Any way to stop this?
Thanks
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

TaskCancelledException is what is thrown whenever one await a task which is cancelled.
In ContinueWith, however, the Task.Status is cancelled (no exception).
Some system task can, unexpectedly cancel. Find out which task are susceptible to be cancelled and handle the cancellation there. Otherwise it's a legitimate bug.

Seriously? I just read your question about what the difference is between Agile and Scrum. Have you heard of Google? You have been on this site long enough to know that you should at least think of doing some research beforehand yourself. This is a simple question for you to look up and I would strongly recommend that you learn to do the most basic searches yourself.

How to generate ID with auto in my program using C# and Firebird database

Try reading the documentation on Firebird. This has nothing to do with C#.

I asked a similar question a while back and never really got an answer, so I'll try again...
I have an application that has a component that works like DropBox. The user puts a file into a folder and it's copied to the server. Then all other users clients will download the file.
I need to determine the correct way of getting the file onto the server. The file will either be copied to the server or FTP'd in.
I need to determine when to use FTP. Obviously if the user is not connected to the network, then the file needs to be FTP'd in. For example, if the user takes their laptop home or on the road - away from the office - they they are not "connected" to the network and FTP needs to be used.
However, if the user is sitting at a desk in the office, then they are "connected" to the network.
The question is: How do I make the determination to FTP the file or just copy it? How can the app know if it's directly connected to the network?
Thanks

One way you could accomplish this would be to check the DNS resolution of the server. If it resolves to an internal address, then the client is local and would be capable of performing a direct copy.
You could also just simply try the copy, or a less intensive get directory listing using the file path in your application. If that fails, failover to ftp transfer.
Is ftp available both internally and externally? If so, it would probably be simpler to utilize it for both transfers. It seems to me that it really wouldn't matter how the file got to the server as long as it was on the server.

OK, how exactly?

I thought of doing FTP either way, but internally it just seems like overkill.

Overkill is implementing more than one server and switching on detection of a network.
Just FTP it and you don't have to worry about the connection type at all.
Checking DNS resolution is probably not a good idea. DNS results are normally cached. Checking for active known company gateway addresses is probably a better bet, but if you just implement FTP, who cares?

I agree. I guess I'm just concerned about performance issues.

How would you distinguish between the corporate network, and any other network?

thinking out loud, ip address range 10.b.c.d, 172.16.c.d, 192.168.c.d for instance and/or a dynamic dns check - Im pretty sure I could 99% of the time give a correct answer. I actually have software that checks the network interfaces in use from a PC and if it's the local wifi connection then 'probes' a set of addresses to see which MySQL server is up .. maybe the same approach would help Kevin
is that what were asking him Eddy ?

I have a web app where users can add any style property they want to the Style attribute of any DOM element on a web page.
The ID and the Style attributes of each DOM element are used to create a JSON array and sent to the backend to be converted into Dotnet objects. Then the deserialized data are used to create or update a CSS file.
I know that to convert JSON array objects to Dotnet objects, usually C# classes are created and properties are then created within those classes. Then the JSON array is deserialized using either JavascriptSerializer or JSON.Net which will populate the properties of the created classes.
The problem is I don't know ahead of time which properties of the Style attribute the user of my app will add to the JSON array.

I can't help but think that a quick and dirty way to accomplish this would be to use a dynamic type to call JsonConvert.DeserializeObject (if you're using JSON.NET), and then use a little bit of reflection to pick out the public properties from here.
[Edit]
Thinking about this a bit further, it should be possible to use the JavaScriptSerializer like this:
Dictionary<string, object> values = new JavaScriptSerializer().DeserializeObject<string, object>(myJson);

The in-build JSON functionality isn't great at these kinds of things. If you use a third party parser like Newtonsoft[^] it supports dynamic JSON better as it will build a collection of objects from the JSON that you can then traverse.
