如何使用实体框架 6 从 .Net 应用程序访问雪花数据库

Question

I am building an ASP.NET application which accesses Snowflake database for getting table data. I have added connection string as below and also added database context class.

<connectionStrings>
    <add name="SnowflakeContext" 
         connectionString="Offline=False;URL=XXXXXXXXX.snowflakecomputing.com;User=XXXXX;Password=XXXXX;Server=localhost;Database=DEMO_DB;Warehouse=COMPUTE_WH;Account=SYSADMIN;" 
         providerName="System.Data.CData.Snowflake" />
</connectionStrings>
<entityFramework>
    <providers>
        <provider invariantName="System.Data.CData.Snowflake" 
                  type="System.Data.CData.Snowflake.SnowflakeProviderServices, System.Data.CData.Snowflake.Entities.EF6" />
    </providers>
</entityFramework>

I want to show the data from snowflake database table on an .aspx page using Entity Framework. I tried creating a grid view control and while adding data source I only get SQL Server and I don't get Cdata Snowflake. I have even installed Snowflake.data package from NuGet. Can someone help me here?

我不是 C# 程序员，但我认为您可能需要安装Snowflake ODBC 驱动程序，然后将网格视图连接到 ODBC 数据源（请参阅本页上的第二个示例）。
