.NET 7 💥 - Angular Authentication with JWT (JSON WEB TOKEN)

In this video we will be going to be exploring the full authentication process from frontend with Angular and backend with WebApi and database as SQLite with JWT 

Todo REST API samples using ASP.NET Core minimal APIs. It showcases:

• Using EntityFramework and SQLite for data access
• JWT authentication
• OpenAPI support
• Rate Limiting
• Writing tests for your REST API 

Today, the Entity Framework Core team announces the first preview release of EF Core 6.0. This release includes new attributes, built-in functions, and database-specific improvements to SQLite and SQL Server capabilities. 

JSON columns

• Introduce common patterns for JSON support that can be implemented by any database provider.
• JSON column support will be implemented for SQL Server and SQLite. (Note that the PostgreSQL and MySQL providers already support JSON columns.)
