About ASP.NET Core and .NET History4:04
This lecture introduces the history of .NET and several applications you can build with .NET. One of them is ASP.NET Core for building rich web applications and APIs.
.NET 8 Download4:29
Downloading the .NET SDK that includes the runtime for building and running the ASP.NET Core application.

Minimal APIs (New features incl)8:02
The Minimal API's is a faster way to create APIs in ASP.NET Core unlike the Controller based APIs that requires the use of defining Controller. The Controller based APIs is more suited for complex APIs but the Minimal APIs can be used to create APIs that contain just few endpoints.
Form Bindings8:43
Generic Attributes2:51
The Generic attribute is a new feature in C# 11.
IExceptionHandler3:26
Support global exception handling
JSON Serialization of IAsyncEnumerable<T>1:07
IAuthorizationRequirementData3:16
ASP.NET Core 8 introduces the IAuthorizationRequirementData interface to define requirements for custom authorization policies.
Redis Output Caching1:32
Several ways to perform caching in ASP.NET Core

The Program.cs Class5:45
Defines configurations on how to run the ASP.NET Core application.
The .NET Core Host1:31
The host is responsible for configuring the application resources and running the kestrel server
Middlewares4:39
A Middleware is integrated into the application pipeline and it performs work before or after the next middleware.
Configuration4:19
ASP.NET Core supports defining application configurations in various places such as app settings, environment variables and command line
Options6:50
Advanced and recommended ways to use work with configurations.
Environments6:24
ASP.NET Core provides several ways to specify the environment the ASP.NET Core application should run on and also environment variables to store sensitive informations.
Dependency Injection (Singleton, Scoped, Transient)13:32
Following the "D" in the SOLID principle that states that "High level class should not depend on low level class. They should depend on Abstractions". ASP.NET Core makes heavy use of dependency injection through constructors and also provides several service lifetimes - Scoped, Transient and Singletons
Error Handling13:14
Several ways to handler errors in ASP.NET core and the new IExceptionHandler that support global error handling in a refined way
Logging6:27
Logging enables gaining insights and informations about what is going on in our applications and databases.
The New Guard Clauses3:39
Guard clauses are a programming concept used to validate inputs or conditions at early in a method or function to ensure that they meet certain criteria. It ensures that errors are handled early in the application

Structure of the Domain Layer3:12
Structuring the Domain Layer which is the heart of the software and the first layer to be developed in the Clean Architecture Project
Country Entity7:25
The TeamLead Entity1:23
The TeamMember Entity3:50
The Project Entity2:01
The ProjectTask Entity4:50
The Todo Entity6:18
The Notification Entity2:25
The IGenericRepository<TEntity> Interface4:53
Defines the contract interface defined in the Domain layer that will be implemented in the Infrastructure layer where the persistence technology is defined by using the "Separated Interface Pattern"
IUnitOfWork4:10
Defines the contract interface defined in the Domain layer that will be implemented in the Infrastructure layer that supports grouping transactions and executing it once.

Configuring the Database and Applying Migrations14:51
Country Controller17:11
Notification Controller8:14
TeamLead Controller7:43
TeamMember Controller2:25
Applying Migrations for Modified Entities4:54
ViewModels and Dto’s with C# Records4:44
Swagger6:37
Routing (Attribute based)5:41
Applying Global Error Handling7:20
Creating a Custom Log class9:33
Integrating the Log BackgroundService20:57
Cursor based Pagination (Better performance over Skip and Take)4:47
Health checks (Basic and Database Health checks)6:16
