I'm writing an OOP project, need to map the object oriented domain into the database, storing objects into the database, I worked with hibernate of java before, now I look for the same thing in C#.
I heard about NDatabase but I dont use it, any one here know and work with it?
For my professional work, I really like EntityFramework. it's powerful and pretty straightforward to use. Here is the guideline to work with (provided by Microsoft): http://msdn.microsoft.com/en-us/data/ef.aspx
i would recommend EntityFramework.
Hope i could help.
Try NHibernate - .net port of hibernate.
Also, take a look at Entity Framework
I think, choosing an ORM solution depends on the database you gonna use. If you're sure it's Sql Server, definitely go for Entity Framewrok since all the advanced features (like code-first) are supported there out of the box. If you go for Oracle, I would suggest NHibernate especially since you already know Hibernate

I am going to develop a project where i would like to use Entity Framework 5 with Code First Approach. I want to use multiple DbContext file. So can anyone please give an example with with a sample project to demonstrate multiple DbContext file. I will be highly grateful.
Thanks .
I don't know if this is a good idea, because there are many side effects. Have a look here:
Entity Framework: One Database, Multiple DbContexts. Is this a bad idea?
But in fact it should be working when you look at the latest comment on this thread. Just define the ConnectionString in the context and set it to the same in every context class.
If you need more informations please provide us with more informations what you are trying to achieve and what's your requirements.

I have been reading about (AOP) Aspect Oriented Programming and I could not find any good article on internet with its implementation in C#. Everyone are talking about AOP Frameworks.
The code the described in below reference is not working at all.
http://www.codeproject.com/Articles/11387/Aspect-oriented-programming-in-NET-Part-II
Can someone share any good implementation code on aspect oriented programming?
Or Else suggest a good AOP Framework to be implemented easily?
As, we are in need to implement AOP in our Project for logging printing and sending mails on completion of specific operations.
Have a look at PostSharp. It is a framework for AOP in .NET that is widely used. In contrast to other frameworks, it uses an approach that weaves the generated code into the intermediate language which is good for performance reasons.
On the website there are also lots of resources about AOP in general and how it can be used. There also is a free edition and a trial version.
However, if you need to only decorate some small portions of your code, using the Decorator pattern or something similar might also be an option.
http://www.codeproject.com/Tips/624586/Introducing-the-KingAOP-Framework-Part-1 seems to fit your need (I've not yet tested it though)

<EDIT>
About this question being off-topic and too opinion-based, I'll try to be more clear. My goal was to undestand if such a tool existed, I was not interested in opinions about what was the best one. At the time I wrote this question I spent quite a good amount of time searching the internet and found just old dead projects but such a tool for java existed and I couldn't belive there were nothing for c#.
I think this question is related to programming (code verification), and it is not really asking for an opinion. Also, it's still not easy to find this information and I think my answer could help saving someone's time.
That said, I'm not an expert of stackoverflow, if you still think the question/answer does not fit the site feel free to delete it.

I've found Moonwalker http://fmt.cs.utwente.nl/tools/moonwalker/ but the last update has been done in 2009 and i don't think it supports .net4.5 (and it's poorly documented).
The answer to this question propose CodeContracts as a model checking tool Model checking tool c# but I've tried using it and I don't think it really is a model checker, not in the same way Java Path Finder for Java is. Im i worng? Can it be used like JPF?
I need to be able to known if a certain part of code is designed in a way that can deadlock. Let's say it's a school thing and even if I'm sure my code is working I must model check it. (Yes we are allowed and encouraged to look on the internet).
As the user #HighCore said, and after lot of searching i can say that a mature and up-to-date tool like the one I described does not exist.
Model checking refers usually to explicit methods, however symbolic methods are equally advanced and arguably more capable for establishing properties of actual code.
For a Turing complete language, the verification problem is undecidable, so model-checking tools usually accept a less powerful language as input. This implies having to convert your problem to that language, before checking. This is why you have not come across any "C# model checking tool".
Have you looked at Boogie and the C#-like Dafny ? These are (essentially) for annotating with Hoare logic.
Alternatively, you can consider model checking your C# solution after (manually) translating it to Promela, then using SPIN.
Related tools (e.g. C-to-Promela translators) are listed here.

I would like to achieve something very similar to Microsoft Access query designer - I am talking about a plane(canvas?)-like surface on which users can place and move controls. Is this even possible?
If it isn't possible with free .NET controls - then are there any paid ones, which offer similar functionality?
Anything is possible if you try hard enough.
I would explore WPF, it will provide capabilities to custom build your own controls and will get rid of that tedious work of keeping the UI updated.
Make sure to follow a good UI pattern if you do end up working with WPF, here is a good video that explains how to implement MVVM in WPF.

Looking for an open source library, for C++, Java, C# or Python, for reading the data from Quicken .qdf files.
#Swati: Quicken .qif format is for transfer only and is not kept up to date by the application like the .qdf file is.
QDF is proprietary and not really meant for reading other than my Quicken, probably for a reason as it is messy.
I would recommend finding a way to export the qdf into an OFX (Open Financial Exchange) or qif file. I have done some financial and quickbooks automation and I did something similar. The problem is if you don't export to an exchange format, each version differs and strange things happen for many conditions that since they aren't documented (QDF) it becomes a bad situation for the programmer.
OFX is what allows online banking, brokerages and apps like mint.com securely get financial data. It is a standard and consistent. Finding a way to this is much better if at all possible.

And i know one other blog where the author was developing a parser for qfx/qif... lemme look it up... googling hasnt helped yet :(
Update: Found one more:
