您可以使用查询类型是EF Core 2.1中引入的。

You can utilize the Query Types introduced in EF Core 2.1.

首先，您需要将类注册为查询类型：

First you need to register you class as query type:

modelBuilder.Query<ClaimDataView>();

然后您可以使用 Context.Query< ClaimDataView>（）代替您当前的 Context.Claims ：

Then you can use Context.Query<ClaimDataView>() in place of your current Context.Claims:

var query = Context.Query<ClaimDataView>().FromSql(...);

更新（EF Core 3.x + ：

从EF Core 3.0开始，查询类型为与实体类型合并并重命名为无键实体类型，因此相应的代码为

Starting with EF Core 3.0, query types have been consolidated with entity types and renamed to Keyless Entity Types, so the corresponding code is

modelBuilder.Entity<ClaimDataView>().HasNoKey().ToView(null);

和

var query = Context.Set<ClaimDataView>().FromSql(...);
