EF 首次加载很慢

1.Code First第一次启动会对比程序中的Model与数据库表（database initializer ),生成Model与数据库的映射视图。使用ef6的情况下，在Application_Start里面添加

using (var dbcontext = new NCContext())
            {
                var objectContext = ((IObjectContextAdapter)dbcontext).ObjectContext;
                var mappingCollection = (StorageMappingItemCollection)objectContext.MetadataWorkspace.GetItemCollection(DataSpace.CSSpace);
                mappingCollection.GenerateViews(new List<EdmSchemaError>());
            }
