One of the first thing you have to do when you are creating a git repository is to create a .gitignore file that tells git to ignore the files specified in the .gitignore file. Since Visual Studio produces all kinds of files it could take a while if you tried to create a .gitignore file from scratch. Well there's a website that will generate a .gitignore file for you. It's called gitignore.io all you have to do is type in the IDE in this case it's VisualStudio without any spaces and the website will generate a .gitignore file for you automatically.

End-to-End ASP.NET MVC 5 : Using Conditional Comments to Support Older Versions Of IE

Older versions of IE have problems supporting the newer JavaScript libraries and HTML5 tags. In the previous blog we've created responsive layout in ASP.NET MVC. In this blog we are going to use conditional comments to support older versions of Internet Explorer (IE). Since IE 9 seems to be the cutoff point we will use it in our conditional comment base condition to decide whether we want to do something different to support IE. We will be working with the MvcApp project.

Step-By-Step Instructions:

1. Open the MvcApp application
2. Open the _Layout.cshtml
3. Inside the <head> tag

    <!--[if lt IE 9]>
      <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
      <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
      <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
    <![endif]-->

JQuery : jQuery.noConflict(); Resolve the $ Conflict

The JQuery library by design uses only two global namespace so that it would not conflict with other JavaScript libraries.

$ - the dollar is used as a reference to JQuery namespace

Also used by Prototype library, YUI and mootools

jQuery - is also used to reference to jQuery namespace, this the more unique reference of the two options, but nobody really uses it

So what do you do if you wanted to use jQuey and Prototype on the same page? Well jQuery can concede the $ sign to the other libraries with the code jQuery.noConflict() function

This sample code shows how jQuery gives up the $ sign to the JavaScript library Prototype

Installing The Northwind Sample Database From Microsoft

The Northwind sample database is probably the most mention sample database of all time. Most of the tutorials on the web uses the Northwind sample database as an example.

The reason is because the Northwind database was initially created for SQL Server 2000. Therefore, most of the newer versions of SQL Server will throw an error when you tried to attach the .mdb file. It is easier to run the SQL script that is provided with the download. In this blog we will go over where to download the Northwind sample database, and how to add to your SQL Server instance using the SQL script.
