silverlight – “CreateRiaClientFilesTask”任务意外失败

尝试在我的RIA域服务进行一些微小的更改(在Silverlight网站应用程序中托管)之后尝试构建VS 2010 Silverlight项目时,此错误已经开始发生.似乎没有理由出现此错误,我无法理解访问被拒绝的部分错误.

我试过的事情

1)彻底清理解决方案中的所有项目并重新构建
2)从框架文件夹中删除所有临时ASP.Net文件
3)从类库中的项目属性中删除链接的RIA服务,该类库失败,清理,重新构建,然后重新添加链接的RIA服务

任何关于从这里去哪里的建议将非常感谢：

解决方法

只是有同样的问题 – 事实证明,改变了“临时ASP.NET文件”文件夹的权限.很容易测试单击.web项目的解决方案资源管理器中的ASP.Net配置.它可能会抛出访问被拒绝的错误,并指向临时asp.net文件文件夹.如果是这样,请在.web项目中打开web.config,并添加一个tempDirectory指令进行编译,如下所示：

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.0" tempDirectory="C:\<SomeDirectoryYouFullyControl>\Temporary ASP.Net Files" />
    </system.web>

重建您的.web项目,并更新您的Silverlight项目中的服务参考.
