UIHint can not resolve template in abstract models

Question

Assume an abstract model like this:

 public abstract class MyClass : BaseEntity
{
    [UIHint("File")]
    public long? DocumentFileId { get; set; }
}

The problem is Cannot resolve template 'File', while there is File.cshtml in View editor templates.

The point is, if I don't define MyClass as an abstract class, error will be solved.

My question is, why editor template can not resolve in abstract classes, and how can I handle it?

Answer 1

This is a bug with ReSharper that was reported almost a year ago. Doesn't look like JetBrains are in a rush to fix it.

However, it shouldn't interfere with your development other than being a nuisance.

Answer 2

I disabled this warning in abstract classes with comments.

// Resharper 8 fails to resolve templates in abstract classes.
// https://youtrack.jetbrains.com/issue/RSRP-373171
// ReSharper disable Mvc.TemplateNotResolved
public abstract class MyAbstractClass
{
    ...

Answer 3

Another option is to suppress the warning at the class level, like this;

[SuppressMessage("ReSharper", "Mvc.TemplateNotResolved")]
public abstract class MyClass : BaseEntity
{
    // ....
