Using Remote Validation wit ASP.NET Core

Hello,

I am trying to create a Remote validation as follows:

    [Remote("CheckValue", "Validate", ErrorMessage="Value is not valid")]
    public string Value { get; set; }

I am using ASP.NET Core (ASP.NET 5) and it seems Remote is not available.

Does anyone knows how to do this with ASP.NET CORE?

Thank You,

Miguel
