How to include Query String in the route resolution in order to allow multiple Actions with the same Method, Route and Query String?

Question

I am converting an ASP.NET MVC (.NET Framework) application to ASP.NET Core MVC. This is strictly a conversion, I cannot make any breaking changes hence I cannot change any Rout

Why not use a single endpoint instead? You don't need to pass Guid's, since it's a GET operation, you can pass strings and cast them later. That way you can send one parameter or the other.

[HttpPut]
[Route("status")]
public async Task UpdateStatus([FromBody] POST_Status statusModel, [FromQuery] string orderGUID = null, [FromQuery] string id = null)
{
    if (!string.IsNullOrEmpty(orderGUID))
    {
        // UpdateStatusByOrderGuid implementation here
        // Guid guid = Guid.Parse(orderGUID);

    }
    else if (!string.IsNullOrEmpty(id))
    {
        // UpdateStatusById implementation here
        // Guid guid = Guid.Parse(id);
    }
    else
    {
        throw new ArgumentException("No valid GUID.");
    }
}

This endpoint should be compatible with both scenarios you specified.
