我正在建立我的第一个Facebook应用程序,我遇到了问题,我对这件事情太过新了解了解最新情况,并希望有经验的人可以理解.这是应用程序的链接,以及错误：
http://apps.facebook.com/nowiknow/
错误：
HTTP Error 500.23 – Internal Server
Error An ASP.NET setting has been
detected that does not apply in
Integrated managed pipeline mode.
我在DiscountASP.Net(littleappbin.com/whoremovedme/)上托管我的应用程序.我的应用程序池管道模式配置为Integrated,服务器使用IIS7.据我所知,我的代码成功请求了所需的权限,但是当被重定向到应用程序时出错了.
这是我的web.config文件：

我为这个凌乱的代码道歉,其中很大一部分是来自我正在讨厌的不同样本.
最佳答案 基本上,你把一大堆混合在一起的东西放在一起.具体来说,列出的所有程序集都是.net 3.5程序集,但您的编译设置为4.0.将您的web.config文件更改为：
<configuration>
<configSections>
<section type="Facebook.FacebookConfigurationSection, Facebook" name="facebookSettings" allowLocation="true" allowDefinition="Everywhere" />
<section name="canvasSettings" type="Facebook.Web.CanvasConfigurationSettings, Facebook.Web" />
</configSections>
<facebookSettings appSecret="xxxxxxxxxx" appId="xxxxxxxxxxxxxx" cookieSupport="true"/>
<canvasSettings canvasPageUrl="http://apps.facebook.com/nowiknow" canvasUrl="http://www.littleappbin.com/whoremovedme" authorizeCancelUrl="http://facebook.com"/>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true" />
<handlers>
<add name="facebookredirect.axd" verb="*" path="facebookredirect.axd" type="Facebook.Web.FacebookAppRedirectHttpHandler, Facebook.Web" />
</handlers>
</system.webServer>
<connectionStrings>
<add name="xxxxxConnectionString" connectionString="Data Source=xxxxx;Initial Catalog=xxxxx;Persist Security Info=True;User ID=xxxxx;Password=xxxxxx" providerName="System.Data.SqlClient"/>
</connectionStrings>
</configuration>
还要确保将Framework目标设置为4.0.有关详细信息,请参见此处：http://msdn.microsoft.com/en-us/library/bb398197.aspx
