Support for .Net Core

[RodrigoSedano]

Hi,

Is there any plan to add support for .Net Core, .Net 5, .Net 6?

Hello, it already supports netstandard2.0 (multiple TargetFrameworks) (but in asp.net core there is a native way to bind models in api actions, so there it is used mostly to send multipart formatted models)

Hi, We have migrated our we application from .net 4.8 to .Net 5 and many of the requests are failing. Before (.Net 4.8) we had this configuration

    public static void Register(HttpConfiguration config)
    {
        var json = config.Formatters.JsonFormatter;
        json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects;
        json.SerializerSettings.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
        config.Formatters.Add(new FormMultipartEncodedMediaTypeFormatter(new MultipartFormatterSettings()));
       ......
    } 

and it seems that the FormMultipartEncodedMediaTYpeFormatter was converting the properties in the request to the correct datatype.

We have request where a "0" string should be converted to 0 int, date string "30-12-2021" string should be converted to 30-12-2021 datetime, "" guid should be converted to Guid Empty and so on.

My question is how we can add FormMultipartEncodedMediaTYpeFormatter so our we application requests works as before.

Hi, I am sorry but this formatter cannot be used in asp.net core for model binding. It is possible to rewrite it to support new interfaces as described here - https://docs.microsoft.com/en-us/aspnet/core/web-api/advanced/custom-formatters?view=aspnetcore-5.0 but, I think it is better to stick with native solutions whenever we can. It should not be very hard to migrate your code to use native model binder - https://dottutorials.net/dotnet-core-web-api-multipart-form-data-upload-file/

Please, let me know in case of any issues.
