asp.net core model binding for one property

Question

I have a complex type

public class Model 
{
    public double D2 { get; set; }
}

And I receive this type inside action

[HttpPost("{id}")]
public string Post(Model model)
{
    return "";
}

Users want to have ability to type numbers with . (point) and , (comma) decimal separators, for example 234.245 and 234,245 are valid decimal types. But framework can't convert this numbers correctly. Is there a way to "catch" the binding for doubles to have ability to normalize symbols before converting to double?

not sure if this works in `.net-core` http://haacked.com/archive/2011/03/19/fixing-binding-to-decimals.aspx/ — adiga, Sep 08 '17 at 14:22
You always can write custom ModelBinder, but I sovle same situation by replacing commas by dots on client side — Anton Sutarmin, Sep 08 '17 at 14:23

Sure, there is a way. Grab d2 as string and then replace . to , and convert into double or whatever you want. For example:

public string Post(string d2)
{
    var model = new Model(){ D2 = Convert.ToDouble(d2.Replace(".", ",")) } 
    return "";
}

If you don't like this way make custom setter in Model by almost the same way
