ws reliablemessaging - WCF ReliableSession and Timeouts -


I have a WCF service which is primarily used to manage documents in a repository.
I used Chanqing channel sample from MS that I can upload / download large files.
Now I have implemented a reliable session with the service and I am seeing some strange behavior.
I am using the time-period value here. 

  This.SendTimeout = New TimeSpain (0, 10,0); this. Opentimeout = new timespan (0, 1, 0); This.CloseTimeout = New TimeSpain (0, 1, 0); This.ReceiveTimeout = New TimeSpain (0, 10, 0); Trustworthy B.E. activityTimeout = New TimeSpain (0,2,0);

I have the following problems:
1 If the service is not there;

I tried to do this with my test client.

Scenario 1: Without a trusted session: I get the following exception: Could not connect to net.tcp: // local host: 8788 / Media management service / AP1 Connection attempt lasted for a time period of 00: 00: 00.9848790. TCP error code 10061: No connection can be made because the target machine has actively denied 127.0.0.1:8788

This is the correct behavior because I have given OpenTime as 1 second .

Scenario 2: With Trusted Session:
I get the same exception:

Could not connect to net.tcp : // Local Host: 8788 / Media Management Service / AP1. Connection attempt lasted for a time period of 00: 00: 00.9692460. TCP error code 10061: No connection can be made because the targeted machine has actively denied it from 127.0.0.1:8788.

But this message comes after about 10 minutes. (I believe that after SendTimeout) here I have enabled the trusted session and now it looks like OpenTimeout = SendTimeout for the customer. Is this the desired behavior?

2: Issue while uploading large files with reliable sessions:
The general rule is to set a big value for maximum reciprocity, sendtime, and receiver timeout Have to do.
But in the case of channel channeling, the size of the maximum received message is not sent as data.
So I have set and received a huge price for the timeout: say 10 hours now the upload is recovering, but it has a side effect, even if the service does not end, (1) the behavior described in Due to customer connection 10 hours from time to time

Please tell me your thoughts on this behavior.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
