使用空间类型EF CORE创建模型

Question

i know that the entity framework team has delayed the spatial types support, but is there a way to tell entity framework to create a column of Geography type for a specified entity?

i'll make the querys using the .FromSql(String) method, but i want teh model build completely from Entity Framework.

Answer 1

You can do that by setting the type in either you migration or with the column attribute here is an example:

        [Column(TypeName ="sys.Geography")]
        public string Geography { get; set; }

With this Update and create work fine, but reading is tricky because EF doesn't won't be able to handle the type. Here is how I get around that mess altogether .
