Unable to setting query parameters to be required

I’m trying to set query parameter on a HttpGet to be required but am unable to do so. Even integers will not be required by default when the swagger.json is created.

[HttpGet]
[Produces("application/json", Type = typeof(IEnumerable<string>))]
[SwaggerOperation(operationId: "ListStuff")]
[ProducesResponseType(typeof(string), (int)HttpStatusCode.BadRequest)]
public IActionResult ListStuff(int id, [Required]string auditId)
{
    ...
}

In the above scenario, both id and auditId will be flagged as not required:

"parameters": [{
	"name": "id",
	"in": "query",
	"required": false,
	"type": "integer"
},
{
	"name": "auditId",
	"in": "query",
	"required": false,
	"type": "string"
}]

Not sure if this is a bug (swear I read somewhere that required is the default), or if I’m doing something wrong?

Same here. [Required] on primitive parameter not show up. [Required] on object parameter works fine.

+1 I got something like

/// <summary>
/// Returns all items in the FV Inventory
/// </summary>
[HttpGet]
public IEnumerable<FvInventory> Get([FromQuery][Required] int projectId, [FromQuery]int? moduleId, [FromQuery] int? fvType, [FromQuery] int? statusId)

And I got something like

"parameters": [{
                "name": "projectId",
                "in": "query",
                "required": false,
                "type": "integer",
                "format": "int32"
            }, {
                "name": "moduleId",
                "in": "query",
                "required": false,
                "type": "integer",
                "format": "int32"
            }, {
                "name": "fvType",
                "in": "query",
                "required": false,
                "type": "integer",
                "format": "int32"
            }, {
                "name": "statusId",
                "in": "query",
                "required": false,
                "type": "integer",
                "format": "int32"
            }]
