Your guide for Rest API authentication is the one I was looking for since last month as I was working on my computer dissertation and there were some unforeseen Rest API authentication errors. However, one of my friends suggested me to get computer dissertation help from someone so I got my all issues resolved. Still, it is worth to read your guide for my viva preparation.

It seems you're encountering a dependency injection issue in an ASP.NET Core project. The error message indicates that the UserManager service cannot be resolved when trying to activate AuthManagmentController. This usually happens when the necessary service is not registered in the Dependency Injection (DI) container www-ncedclouds.com

Ah, I am glad I don’t have to get into this technical stuff because I can’t get my head around it. I provide Dissertation Writing Services London- based and I just have to research and write. I guess my brother may find this post useful as he is into coding and development. I am sharing this link with him.

This is an excellent, thorough tutorial on implementing JWT authentication in an ASP.NET Core API. The step-by-step instructions make it easy to follow along and understand the process. One suggestion to make this an even more well-rounded learning resource would be to include a section on online report writing about the finalized API. For example, provide some guidance on how developers could summarize the API architecture, endpoints, and overall functionality through online report writing. This would reinforce key learnings and help cement developers' understanding. Overall though, a very helpful guide to securing APIs with JWT and role-based authorization.
