什麼程序集是System.Ext？

Question

我們正在構建一個需要System.Ext命名空間的NETMF項目。什麼程序集包含它？

我們已經嘗試了「添加引用」>「.NET」>查找System.Ext程序集。我們也嘗試了MSDN System.Ext Namespace的文檔，但沒有提及裝配。

看這裏 - 看來，你需要添加一個引用到MFDpwsExtensions.dll

Right-click the References folder in your Visual Studio project. 
Choose Add Reference from the context menu 
In the Add Reference dialog, choose the .NET tab. 
Select MFWsStack.dll in the list, then click OK. 
Repeat steps 1 to 3, this time adding MFDpwsExtensions.dll. 
If your project is a for a device hosting a service, repeat steps 1 to 3, this time adding MFDpwsDevice.dll. 
If your project requires DPWS client functionality, repeat steps 1 to 3, this time adding MFDpwsClient.dll.
