我有一個Sybase ASE數據庫的實體模型,我正在嘗試使用Effort Framework爲它創建單元測試。我能夠在我的主項目和單元測試項目中使用實體模型訪問數據庫,但是當嘗試使用Effort創建內存數據庫時,我得到一個異常。Effort Framework無法識別實體模型模式
問題代碼在單元測試項目
public SetUpShims()
{
string connString = System.Configuration.ConfigurationManager.ConnectionStrings["CoPathDataContext"].ConnectionString;
MyDbContext context;
// CreateTransient throws exception
EntityConnection conn = Effort.EntityConnectionFactory.CreateTransient(connString);
context = new Data.CoPathDataContext(conn);
}

看.csdl後實體制作的.ssdl文件,我相信我發現了導致問題的字段。
SSDL
<Property Name="sequence_num" Type="float" Precision="24" Nullable="false" />
CSDL
<Property Name="sequence_num" Type="Double" Nullable="false" />
我試圖消除從SSDL領域的精密屬性,但但我仍然收到了同樣的錯誤。 (即使它確實起作用,當模型重新生成時,更改可能不會持續)
有人想到是什麼導致異常以及如何解決它?
任何更新? – MiloTheGreat 2017-08-14 07:02:56
@MiloTheGreat不幸的是,我們發現的唯一解決方案是編輯EDMX以刪除導致問題的列,並在我們需要列時使用存儲過程訪問表。 – 2017-08-16 16:26:19
@MiloTheGreat我爲此打開了一個GitHub問題,您可以按照[這裏](https://github.com/tamasflamich/effort/issues/78) – 2017-08-16 16:34:09
