Validate model state not working?

[wayne-o]

Description

I am trying to use #316 by adding this to my Models:

 [Required(AllowEmptyStrings=false)] 
[StringLength(30, MinimumLength = 5, ErrorMessage = "Invalid - Name needs to be at least 5 characters long")]

And this in my startup:

 services.AddMvcCore()
                .AddDataAnnotations()

But it seems to completely ignore it -is there anything else I need to do to get this to work?

...

Environment

• JsonApiDotNetCore Version: latest stable (v2.5.2)
• Other Relevant Package Versions:

I'm trying upgrading to the latest beta - I'll come back with the result

No change :/ even latest does not seem to apply

Have you enabled ValidateModelState ? This was put behind a feature flag since it wasn't initially checked and would have been a breaking change.

JsonApiDotNetCore/src/JsonApiDotNetCore/Configuration/JsonApiOptions.cs

Lines 128 to 136 in 491a6cb

	/// <summary>
	/// Whether or not to validate model state.
	/// </summary>
	/// <example>
	/// <code>
	/// options.ValidateModelState = true;
	/// </code>
	/// </example>
	public bool ValidateModelState { get; set; }
