＆QUOT; CreateRiaClientFilesTask＆QUOT;任务意外失败 [英] "CreateRiaClientFilesTask" task failed unexpectedly

问题描述

此错误已经开始尝试一些小的改动，以我的RIA领域的服务，这是Silverlight的网站应用程序内托管后，建立我的VS 2010的Silverlight项目时存在的。似乎没有理由为这个错误，我无法理解的拒绝访问错误的一部分。

This error has started occuring when attempting to build my VS 2010 Silverlight project after some minor changes to my RIA domain services, which are hosted within the Silverlight website application. There appears to be no reason for this error and I cannot understand the access denied part of the error.

东西我曾尝试：

1）解决方案，并重新构建所有项目的全面清理
2）所有临时ASP.Net文件的删除从框架文件夹
3）从类库失败项目属性，干净，重新构建，然后重新添加链接RIA服务的链接RIA服务拆卸

1) Full clean of all projects in the solution and re-build 2) Deletion of all temporary ASP.Net files from the framework folder 3) Removal of linked RIA services from project properties from the class library that is failing, clean, re-build and then re-add linked RIA services

在哪里可以从这里去任何意见将是多少AP preciated：

Any advice on where to go from here would be much appreciated:

推荐答案

刚刚有同样的问题 - 原来的东西改变了对临时ASP.NET文件文件夹的权限。这很容易测试。点击ASP.Net配置在Solution Explorer中的项目名.web。它很可能会抛出一个访问被拒绝的错误，并指出你的临时asp.net文件的文件夹。如果是这样，在你的名.web项目开放的web.config文件，并添加一个tempDirectory指令编译，像这样：

Just had the same problem - turns out that something changed the permissions on the "Temporary ASP.NET Files" folder. It's easy to test. Click the ASP.Net Configuration in solution explorer for the .web project. It'll likely throw an access denied error and point you to the temp asp.net files folder. If so, open web.config in your .web project and add a tempDirectory directive to compilation, like so:

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

您的重建项目名.web和更新您的Silverlight项目的服务引用。

Rebuild your .web project and update your service reference in your silverlight project.
