Implementing Advanced RESTful Concerns with ASP.NET Core 3

Fully functioning sample application accompanying my Implementing Advanced RESTful Concerns with ASP.NET Core 3 course.

The course tackles paging, sorting, data shaping, HATEOAS, advanced content negotation, custom media types, caching (in-depth) and concurrency. If you're interested, you can find it here: https://app.pluralsight.com/library/courses/asp-dot-net-core-3-advanced-restful-concerns/table-of-contents

XmlDataContractSerializer middleware fails for Dictionary<string, object>

Lesson 34. Demo - Implementing HATEOAS Support After POSTing)
Issue : change Accept Media type to application/xml

AddXmlDataContractSerializerFormatters middleware fails while serializing generated response for Dictionary<string, object>

In our case when we add links to Dictionary<string, object> for media-type *Accept: application/xml.

here are my dictionary's keys and values

Key1            value1
someKey1     someValue
key2             value2
someKey2     ICollection<TSource>

Serialization of this dictionarty response fails for media-type *Accept: application/xml.

Error on shaping collection resource

If I shape an author and don´t include the id field, it throw an exception on AuthorsController/GetAuthors on this block because the authorAsDictionary does´t have the id field:

var shapedAuthorsWithLinks = shapedAuthors.Select(author => { var authorAsDictionary = author as IDictionary<string, object>; var authorLinks = CreateLinksForAuthor((Guid)authorAsDictionary["Id"], null); authorAsDictionary.Add("links", authorLinks); return authorAsDictionary; });

I´m trying to figure out how to fix it. Some help?

New property in Author (XML/Input) not Binding

Hi @KevinDockx
I added a new property in CreateAuthorRequest named City and the same in XML request and this City is not binding when I inspect in Controller. (please check 2 attached screenshots)

It works if we choose media type, : application/json but it doesn't work with XML input

Hi Kevin!!Could you please post an example of Cache Expiration and Validation!!

wrt to retail scenario ie. an client app (angular) collecting product summary from API
demarcation of data is mostly as is derived from real world retail producr , consider Laptop and its supported Accessories wrt to multiple brands API supports.
ques is how to ensure reliability of data sent in response from API endpoint via a Httpget (api/Laptops/GetProducts?fields=Id)
is maximum mostly considering nature of data , resource representation may be different for each Vendor.

Replace/remove PropertyMappingService

Hi @KevinDockx ,
I'm just curious if you see a problem to remove or change the PropertyMappingService since we got the same information in AutoMapper.
May-be, there is a way to utilize "mapper.ConfigurationProvider.Internal().GetAllTypeMaps()" instead of mapping all properties twice - once in profiles and once in PropertyMappingService.
