Why coding standards are important?

Yesterday, I had a discussion with friend about coding standard are important and why you need it?  So I thought it will be a good idea to write a blog post about it. Followings are some reasons why coding standard are so important.

  • Readability:  coding standard will increase overall code readability means if you follow you coding standard defined other people also know that what you have written. They don’t need to debug the code to know what function this code will perform.
  • Code Style: Every programmer have different style of writing code. So if we don’t have coding standard then Programmer ‘A’ can write variable in camel casing while other  will prefer to use Pascal case. So different modules have different coding styles.Which makes code hard to understand.
  • Code Reviews: Code review is an important part of any software development. If you don’t have a coding standard defined then it will take more time to do code review.
  • Error handling/Exception handling : The another benefits of coding standard is standardized way of handling errors. If you don’t have coding standard defined then each programmer will handle errors in unique way that could create a problem of identification of a bug  in software development .
  • Maintenance: Large enterprise software's will have  long life span. So if there is any enhancement or maintenance work is required with the help of coding standard any people can understand code easily and easily do the some changes.
That’s it. Hope you like it. Stay tune for more!

So I thought it will be a good idea to give an overview how database migration works in Entity Framework Core RC2. This post will cover a basic scenario where we are going to create the database with existing ASP.NET Identity migration and then we are going to create a new model and have that migration applied in the database.

How to use Entity Framework Migrations: Let’s get started, To demonstrate entity framework core migrations, I am going to create a sample asp.net core web application like following.



Once we select asp.net core application it will appear the following dialog.

Update: I have written a new blog post about better approach to create a PDF with asp.net mvc- You can find that following location.- A Better Solution to create PDF with Rotativa and ASP.NET MVC
In this post we are going to learn how we can easily create PDF from ASP.Net application with the help of Razor PDF NuGet package.

About Razor PDF:
This NuGet package is created by Al Nyveldt It internally uses ITextSharp an open source PDF convertor library. RazorPDF uses Razor View engine to create iTextXML which is in tern used to produce PDF file. You can get more information about that at below link.

Example(Creating PDF with ASP.Net MVC):
So what we are we waiting for ? Let’s create a simple example. To create example first thing we need to a create and ASP.Net MVC application.
