Cannot convert lambda expression to type 'string' because it is not a delegate type
问题 In my controller i am trying to use include with EF4 to select related entities, but the lambda expression is throwing the following error, i have the related entity defined in the Entity class like public class CustomerSite { public int CustomerSiteId { get; set; } public int CustomerId { get; set; } public virtual Customer Customer { get; set; } } Then in my controller i have var sites = context.CustomerSites.Include(c => c.Customer); public ViewResult List() { var sites = context
