（不是Web服務平臺獨立？）Web服務在.net 2.0+項目中工作，但不是.net 1.1

我已經通過創建一個快速.net 3.5項目進行測試的同事提供了Web服務。該服務公開了一個返回DataTable的簡單方法，並且一切正常。（不是Web服務平臺獨立？）Web服務在.net 2.0+項目中工作，但不是.net 1.1

生產項目.NET 1.1，雖然，我得到創建Web服務對象上線運行時錯誤：

 
The XML element '' from namespace 'web/InternetData' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.

我首先想到的是創建一個單獨的2.0項目轉儲數據以供1.1項目重新使用，但這似乎是不必要的一步。

Web服務意味着與平臺無關 - 除非你做一些事情使它們依賴於平臺。就像返回依賴於平臺的數據一樣。有點像DataTable。

這是一個很好的觀點。返回類型似乎是我的1.1應用程序無法解析的。我最終在2.0中編寫了一個數據轉儲，然後被1.1應用程序吞併。不理想，但它的工作原理。 – John 2009-11-04 17:38:31
