.net - Considerations for implementing LINQ to SQL or Entity Framework now, intending to use NHibernate later -


I have a preliminary release deadline for a client-server application in which there will be a lot of repeated releases.

NHM is the ORM of choice, to a great extent, and my desire to gain experience with it.

The problem is that I still have not got the opportunity to get the NHibernate spike, and I'm afraid that by doing this I'm going to throw me out of the track to get on the deadline. Therefore, I am thinking that I can use the SQL or unit framework from the LINQ now because I have some experience with those , and then when I enable I swap to NHibernate.

Considering this scenario, what should I do to eliminate or design a data layer to prevent major headaches when going to NHibernate?

Edit:

As per the post given below, L2S is going to limit me to table-per-square, which can be manageable in the first run But I do not want to go down that path down Let's assume the future migration of the NH from EF.

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...
