Daily interview Question #9: what is the purpose of ref and out parameters in C#?

          Ref keyword is used to send the particular parameter as a reference to the function or subroutine.
          In some cases we may want to return value from the function but we don't want to use that variable within the function. We just get back some value, that's all. In these kind of scenarios we may go with 'out' parameter.
          The main difference between the two is, before passing ref parameter we must initialize the particular variable. But this kind of initialization is not necessary with 'out' parameter.

ASP.Net Forums - FAQ #2 : ASP.Net Project Ideas

                                              ASP.Net Forums have tons of Questions. I have preferred some most frequently questions and give a detailed explanation here. This one also I encountered a lot in the ASP.Net Forums. Most of the college students and beginners are asked about the below questions:
How to start an ASP.Net Web Projects?
Where to get some basic ideas about web based projects?
                    In this post I just want to guide those people from my practical experiences.

Prerequisite – Software:
                Before start your project you need the below softwares:

1. Visual Studio
2. .Net Framework
3. SQL Server   

                        For students and beginners express version of visual studio is enough. While this writing Microsoft released Visual Studio 2013. You can download the Visual Studio 2013 express for web development here. With that installation, .Net framework 4.5 also installed. So there is no separate download is not necessary.

                         Each and every website that are developed are data centric or data driven. That are data are stored and retrieved from a database like SQL Server. So you must need that one also.

                         For SQL Server also Microsoft provide express version. You can get it SQL Server 2008 Express with SP2 here and SQL Server 2012 here.

                        For the above software installation you must need Windows 7 with SP1 or Windows 8.

Prerequisite – Skills:

              The below are the must have skill sets that are required for every beginner in ASP.Net.

1. .Net Architecture (CLR and BaseClass Library)
2. C# or VB.Net Language
3. ADO.Net
4. ASP.Net (Web Form, Worker Process, AppDomain, Session, Cache, Authentication etc)

               It is better how the .Net frameworks works which helps to the developer to grasp the rest of the things easily. If you want to go with ASP.Net you should learn any one of the .Net compatible language such that C# or VB.Net. ADO.Net always deals with Database related objects like Datasets, Datatables etc. In beginner level choosing Web Form will give a easy to move way in ASP.Net. The above lists are specific to .Net.

Some Good Books for ASP.Net:
         Below are my personal suggestion to sharpen your skills in ASP.Net as well as .Net Languages such as C# and VB.Net in some extend.

1. Programming ASP.Net By Dino Espotio (From Microsoft Press)
2. Professional ASP.Net 2.0/3.5/4.5 (from wrox publications)
3. C# 4.0 – The Complete Reference By Herbert Schildt

Online Tutorials & Trainings for ASP.Net:
               For ASP.Net technology, there are so many good online tutorial sites available. Some of them for your reference:
