Can I define properties in partial classes, then mark them with attributes in another partial class?

Question

Is there a way I can have a generated code file like so:

public partial class A {
public string a {get; set;}
}

and then in another file:

Answer 1

This is my answer
different class files or you can combine the metadatas in a same file but keep the namespace the same..so they can see each other obviously.

keep in mind when you update your model like add more columns you have to update the project class too.

--your model class
public partial class A {
    public string a {get; set;}
}

--your project class 
public class Ametadata {
     [Attribute("etc")]
     public string a {get; set;}
}


[MetadataType(typeof(Ametadata))]
public partial class A
{
}
