"CreateRiaClientFilesTask"任务意外失败

Question

在对我的RIA域服务进行一些细微更改(尝试在Silverlight网站应用程序中托管)后,尝试构建我的VS 2010 Silverlight项目时,此错误已经开始.似乎没有理由出现此错误,我无法理解错误的访问被拒绝部分.

我尝试过的事情:

1)完全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)从类库中删除项目属性中的链接RIA服务,该类库是失败的,干净的,重新构建然后重新添加链接的RIA服务

任何关于从哪里出发的建议都将非常感激:

刚出现同样的问题 - 事实证明,某些内容更改了"Temporary ASP.NET Files"文件夹的权限.它很容易测试.单击解决方案资源管理器中的ASP.Net配置以获取.web项目.它可能会抛出拒绝访问错误并指向temp asp.net files文件夹.如果是这样,在.web项目中打开web.config并将tempDirectory指令添加到编译中,如下所示:

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