UseExceptionHandler vs GlobalExceptionMiddleware

Question

I am just trying to understand while ASP.Net Core 2.x offers the possibility of app.UseExceptionHandler("/Error") here, and even UseStatusCodePagesWithReExecute here Do we still need to implement a global exception handling middleware like what is being discuss in here? or even here which is know by GlobalExceptionMiddleware and needs to be registered in the most button layer of chain of layers in .Net Core

Answer 1

I updated the Microsoft document to make this question clear.
