部署后，ASP.Net Web服务不返回任何数据

Question

Visual Studio 2010
.Net framework 4.0
IIS 7.0
Windows Server 2008

 within a visual studio solution I have: - Website project - Webservice project 

基本上，网站功能会调用Web服务方法来进行SELECT / INSERT / UPDATE数据。

This works fine when I try to run through the visual studio, but does not work on the server. 
 - using Visual Studio 2010 express on the server, the solution compiles successfully and gets the requested data. 
 - however, if I try to retrieve some data from deployed web service like:
 http://localhost/LTC_webservice/LTCWebService.asmx/GetWorkTypes

我没有桌子..所以我的网站上显示此页面：

找不到表0。

IIS Settings: 
- using ASP.Net v4.0 application pool 
- Managed Pipeline = Classic
- ISAPI and CGI Restrictions: allowed on ASP.NET v4.0.30319

我在这里想念什么？

Answer 1

数据库连接应该是SQL身份验证，而不是Windows身份验证。 我的连接字符串是使用Windows身份验证而不是具有用户ID和密码的SQL身份验证连接到数据库的。
