我剛剛部署了一個我一直致力於開發新機器的asp.net web應用程序。這是一個從3.5轉換爲4.0的項目。出於某種原因,當我嘗試通過我的IIS網站在默認網站下擊網站時出現以下錯誤:ASP.NET Web App使用錯誤的(2.0)CLR版本(而不是4.0)
無法識別的屬性'targetFramework'。請注意,屬性名稱區分大小寫。
它列出這個作爲是ASP.NET錯誤頁面上的配置錯誤:
<compilation debug="true" targetFramework="4.0"/>
然而,我注意到,在錯誤頁面的底部,版本信息表明它正在使用版本2而不是版本4.任何人有關於如何解決這個問題的想法?
我已經確定我的默認網站使用.net 4 /集成應用程序池,並且在更改完成後,我會循環iis。仍然不是運氣。這裏是我的整個web.config文件:
<?xml version="1.0"?>
<configuration>
<appSettings/>
<connectionStrings>
<add name="EventMasterConnectionString" connectionString="Data Source=localhost;Initial Catalog=BashBidder;Integrated Security=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>
<!--
Set compilation debug="true" to insert debugging
symbols into the compiled page. Because this
affects performance, set this value to true only
during development.
-->
<compilation debug="true" targetFramework="4.0">
</compilation>
<!--
The <authentication> section enables configuration
of the security authentication mode used by
ASP.NET to identify an incoming user.
-->
<authentication mode="Windows"/>
<!--
The <customErrors> section enables configuration
of what to do if/when an unhandled error occurs
during the execution of a request. Specifically,
it enables developers to configure html error pages
to be displayed in place of a error stack trace.
<customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
<error statusCode="403" redirect="NoAccess.htm" />
<error statusCode="404" redirect="FileNotFound.htm" />
</customErrors>
-->
<pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/></system.web>
<!--
The system.webServer section is required for running ASP.NET AJAX under Internet
Information Services 7.0. It is not necessary for previous version of IIS.
-->
</configuration>
感謝您的幫助!
咦?我相信OP想要在4.0版本中運行他的應用程序。 – Victor 2011-02-13 15:42:14
