EF 6 + .NET 4 遇到資料載入錯誤的畫面

EF 6.1.3 + .NET Framework 4

若系統只有 .net 4 系統要執行 Telerik RadGrid 載入資料時, 系統將會出現類似下面的錯誤

Duranet2Model.csdl(2,9) : warning 0005: Could not find schema information for the attribute 'Namespace'.
Duranet2Model.csdl(2,35) : warning 0005: Could not find schema information for the attribute 'Alias'.
Duranet2Model.csdl(2,48) : error 0005: The 'http://schemas.microsoft.com/ado/2009/02/edm/annotation:UseStrongSpatialTypes' attribute is not declared.
Duranet2Model.csdl(2,2) : error 0010: The element Schema in namespace http://schemas.microsoft.com/ado/2009/11/edm was unexpected for the root element. The expected Schema in one of the following namespaces: http://schemas.microsoft.com/ado/2006/04/edm, http://schemas.microsoft.com/ado/2007/05/edm, http://schemas.microsoft.com/ado/2008/09/edm.




解決方式




安裝 .NET Framework 4.5.x 就可以解決
