In this post, we will explore the implementation of CRUD (Create, Read, Update, Delete) operations for Applications. As we continue, we will also delve into the world of Code First Migrations and tackle some common issues that can arise during the migration process.

In a previous post, we learned how to implement functionality for the Add, Edit, and Delete actions. However, it's important to note that any changes made will be lost once the project is no longer running, as we are using a static variable, OrganizationsData, which is not persisted.

In our previous post, we introduced a Razor Page tailored for tenants, featuring three essential action buttons: Add, Edit and Delete. In this post, we'll delve into the implementation of these buttons' functionalities.

If we recall from the previous post, one of the requirements is to incorporate a multi-tenancy feature into our project. In this article, I will focus on the presentation level for tenants.

Creating our first project using ASP.NET Core

Creating our first project using ASP.NET Core

Why and what is smoke testing?

Recently, I have started my journey to learn C programming using Visual Studio Code and Mingw-w64. What is Mingw-w64? It is created to support GCC compiler on Windows systems. GCC is the GNU Compiler Collection and GNU (stands for GNU’s not Unix) is key component to help build operating systems like Linux.

There was one particular ASP.NET Core project that I have left it for quite a long time. Therefore, I would need to refresh my memory in order to understand how it works by first running it in debugging mode in Visual Studio 2017. To my suprise, as soon as I pressed F5, there was a popup error as below:

I was trying to access my localhost ASP.NET Core MVC website from another computer which sits in different LAN. Thus, I tried to google around and it does show some good solutions, however, I would need to refer to multiple places to get the final solution. So, I thought I could just compile them in one single post, in case there are some people looking for one-stop solution. FYI, This solution is only for Windows 7 or Vista.

ASP.NET Identity is much more powerful than legacy ASP.NET Membership which includes the support of external authentication from 3rd party providers. In one of my projects, I have an ASP.NET MVC app communicating with another ASP.NET Web Service app which contains all core business logic and data access. The MVC application essentially is just another Presentation Layer which handles simple rule processing. While I was trying to migrate to ASP.NET Identity, I was stuck on trying to decouple database access from ASP.NET Identity, specifically the SignInManager class in the MVC application.

Just arrived at the office, without breakfast, I had complaint from boss that our website was very slow. Looking at the website, it was very slow indeed, only after a good few minutes, the website only started to load some texts barely while you still can see the rolling icon on web browser’s tab.

Nowadays, technology has become an integral part of any organization, for instance, manufacturing, marketing, operation and so no. Therefore, it is fair enough to conclude that technical experts have become an important factor for a company or organization success.

As I continued doing my migration process to convert my existing project from ASP.NET Web Form to ASP.NET MVC using Entity Framework from my previous post, I had abit of issue with SQL LEFT JOIN. Basically, the SQL keywords return all records from left table and matched records from right table. NULL is returned from right side if there is no match.

As I was doing a migration process to convert existing project from ASP.NET Web Form to ASP.NET MVC using Entity Framework, I came across a bunch of SQL statements. Yeah, I know, we should not have any SQL statements in C# codes. Thus, while I was going thru all my codes to remove all SQL statements.

In the wake of ever changing technology, there are still lot of new technical knowledge that programmers need to grasp. In short, it’s essential for programmers having this capability of quickly grasping new knowledge as it will determine their level of career development and outlook. The most important and fundamental skillset for programmers are learning ability and ability to analyze and solve problems.
