What is Dependency Injection in ASP.NET Core? Dependency Injection (shortform "DI") is an ASP.NET Core technique to achieve loosely coupling between objects so that the applications can be maintained in an easy manner. Here DOT NET runtime engine automatically injects objects of dependency classes mainly through the constructor of the Controllers. Thus making the job of the developer much easier.
Let us create a ASP.NET Core 6.0 app to demonstrate the working of Dependency Injection feature. I will give you the complete knowledge of this feature in this tutorial so make sure you read it fully on one go.

The ASP.NET Core Configurations settings are configured on 3 files:
These configuration settings tell the ASP.NET Core app how it should work based on the users interaction. In this tutorial we will look into the various ASP.NET Core Configurations which will provide you with a solid foundation for understanding the coming DOT NET Core topics. I will start by creating a new project using empty template so that you can clearly understand how each of the configuration settings work.

ASP.NET Core Identity Policy is a collection of requirements a user must have for him to be authorized to access a resource on the app. Identity Policy based Authorization can contains additional requirements for Identity Roles and Claims for a user to have, and this helps us to build richer authorization structures in our apps.
For example - we can create an Identity Policy named "MIT" that contains 3 requirements say "Grade A in High School", "18 Years or less", "Nationality American". Now we can apply this policy on the MIT portal and this will allow only those students to apply for a graduate course who have these 3 things:
If we want to add custom user properties like "Age, Country & Salary" to the ASP.NET Core Identity Users then we can do this by adding Custom User Properties to the User class. The User class, as we all know, inherits from the IdentityUser parent class. These new custom properties are added as new columns to the AspNetUsers table of Identity database.
