Hi There! 👋

Thank you for your visit!

This site is currently on-going development. On-going migration of old articles from my old site to this new site. Some old notes are still on drafts, I will deploy soon.
I write and document random things, but majority of the write ups you can find in here are more of my experience and learnings as a software developer, as this is the background I come from.
Majority of the articles/notes on this website are real life scenarios on software development, mostly based on .NET methodologies.
Not all links in this website are particularly articles, these may just be notes on the daily programming dilemma I’ve encountered.
Think of it as a sort of notebook - a place to jot down interesting ideas and questions which we can think of some time.
Do give a 🌟 on Github !
From time to time I accept side gigs that pique my interest. Contact me or just say Hi! at jrc@artcdc.com

This way we will just consume the managed module in our web.config and we will don’t have any changes needed in our app....

SAML SSO Authentication

What is SAML? First what is SAML? It is mainly use for authentication. It’s main role is to standardize web applications on authenticating and transfer data between the identity provider and the service provider. It improves user experience and the user will only remember one password through out the enterprise systems. OAuth vs SAML? The primary difference between OAuth and SAML is that we mainly use SAML for authentication and OATH for authorization....

ValidateAntiForgeryToken: Purpose and Usage

In simple explanation found on Microsoft docs: ValidateAntiForgeryToken represents an attribute that is used to prevent forgery of a request. In other terms this attribute is used to prevent cross-site forgery attacks. Cross site forgery is an attack that posts to your site/form to attempt to submit a hiddent content using an authenticated user’s credential. Let’s have a realistic scenario of this cross site forgery. Supposed you are logged in to your online banking account....

Visual Studio Project Types

Today, I encountered an error/bug on my Visual Studio. Working with the MVC project I am doing, while trying to add a scaffolding controller. I can’t seem to find the ‘Add Controller’ in the context menu of Controller folder. Sometimes a simple Clean all, Rebuild all works easily. Sometimes it’s just a bug on Visual Studio itself and a simple reboot of VS or reboot of your machine will work....
