Introduction
Some line of business (LOB) applications or internal systems have a predefined set of users and corresponding login information. In situations like those, using a database mechanism to store user information is an overhead. Combine this overhead with Microsoft’s heavy-duty implementation of the Identity framework with persisting concerns in the Entity framework, and you have a recipe for a headache. Those frameworks might be useful in certain situations, but here we have a limited scope and, in situations like this, we can, instead, take a lighter approach towards this functionality.
In this post, we will look at a way to implement authentication functionality in an ASP.NET Core Web application. We will go through all the steps and how things are put together to achieve the desired result. The source code is available in this GitHub repository.
