workflow - Guidance Needed for WF and Parallelism in ASP.Net -


The more I search for certain topics in relation to ASP.net, the more I think how and where the ASP TNN.T.T. To implement certain things correctly in realm (both webforms and mvc)

Workflow Foundation

I like to use WF; However, what I have read is that it is not recommended for ASP.NET app due to 1 workflow hosting environment, according to the App Domain restriction. Now I have not seen where this restriction has changed but after the old DNS 3.0 (.netfx) days I still can not find any information about this restriction. I'm looking for advice to create workflow in services which looks good; However, there are not such exact same limitations, where the service is often hit repeatedly, will it result in some performance issues? Is there a place for WF in ASP.net and if so, where?

Parallel processing

The same thing for the sake of the same thing because of the method of setting up a thread pool in the application pool of IIS, I always have multi-threaded ASP Net applications have been viewed / read. Now with Net4 and with multi-core processors everywhere, multi-threading is again one of the hottest topics. I like what I see in parallel extensions in 4.0; However, is this advice still not in ASP.net or are there some places where it will be recommended at this point?

Is there advice still on these two items from the year before? Should not they still be in ASP.NET world?

Thanks

Multicast is quite irrelevant in ASP.net - the reason for it That any code writing in ASP.NET is meant to handle the same request. There are two main reasons for using multiple threads in other types of applications:

  • Another thread works, while updating the URI - the user does not have anything on the web app Unless the whole work is done
  • Better performance by using all available cores - other cores do not have much advantage if other users are not busy with the requests.

The workflow has been designed for a long time, the ongoing work - do not use it, where the button on the button will have to do some simple code. Remove the need for an immediate reaction and a simple queue takes care of the most probable performance problems. I have used WF inside ASP.Net pages, but if I need speed or a large number of users, then I will not do this.

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...
