[Question] Understanding custom typed results

[ayuksekkaya]

Hello @mehdihadeli, Thank you for this template. I believe there are many helpful patterns in here. I had a question about the custom TypedResultsExtensions you have. What is the benefit of using InternalProblem UnAuthorizedProblem?

In the CreateProductEndpoint for example, the endpoint is defined as:

async Task<
            Results<CreatedAtRoute<CreateProductResponse>, UnAuthorizedHttpProblemResult, ValidationProblem>
        > Handle([AsParameters] CreateProductRequestParameters requestParameters)
        {

What is the advantage of this over just doing

        async Task<
            Results<CreatedAtRoute<CreateProductResponse>, UnauthorizedHttpResult, ValidationProblem>
        > Handle([AsParameters] CreateProductRequestParameters requestParameters)

With the "UnauthorizedHttpResult" directly from the Results class?

Also can you explain the usage of the "MapCommonEndpoint"? It's not being used, so I am not sure how it fits as opposed to the other "Map" methods

Hi,
we can use it for auto generating open-api documentation instead of adding them manually, similar to built-in .Net ValidationProblem but for other exception types.
