Win7下VS2010使用“ASP.Net 3.5 Claims-aware Template”建立ClaimsAwareWebSite报"HRESULT: 0x80041FEB"错误的解决办法

问题描述：

使用VS2010的WIF开发模板建立“Claims-aware ASP.NET Site”、“Claims-aware WCF Service”，下载安装后，建立网站时，报错"HRESULT: 0x80041FEB"，其余模板“ASP.NET Security Token Service Web Site”、“WCF Security Token Service”的STS时无此问题；

问题分析：

插件发布地址http://visualstudiogallery.msdn.microsoft.com/34783f43-91b0-42ee-90f4-b82bdb4ac91f?SRC=VSIDE有就此问题的解决方案，此问题由插件自身的Bug致使。

The Template has a bug which can result in the error "HRESULT: 0x80041FEB" after trying to create a new project out of it. To resolve the problem follow these instructions:
After you have installed the template, open the file "%AppData%\Local\Microsoft\VisualStudio\10.0\Extensions\Microsoft\ASP.Net 3.5 Claims-aware Template\1.0\~PC\ProjectTemplates\csClaimsAwareASPNETSite.zip\ClaimsAwareASPNETSite.webproj" with Notepad++ or any similar advanced text-editor (it should be possible to display special characters/bytes). The content of the file is simply (without the "---" lines which mark beginning and end of the file content):
---
C#
$targetframeworkversion$
---
However, at the end of the second line (and therefor at the end of the file) there's a NUL byte/character (of the byte value 0x00) which will be displayed as such only in an advanced text-editor like Notepad++, in the standard Notepad editor it will be displayed as a space character. No matter in what editor you are and how it's displayed to you, delete this last character, so that the file will end with the $ sign, and save the file. Now you can use the template in Visual Studio without any more errors.

但在“"%AppData%\Local\Microsoft\VisualStudio\10.0\Extensions\Microsoft\”目录下未能找到文件夹“ASP.Net 3.5 Claims-aware Template”，故暂时没法采用去掉空格的办法。

问题解决：

以建立“Claims-aware ASP.NET Site”时遇到问题的解决方法为例：

1、本机搜索关键字“ClaimsAwareASPNETSite.webproj”，在以下目录找到模板安装文件夹，

C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\ProjectTemplatesCache\Web\CSharp\0

2、复制该文件夹建立到，“%AppData%\Local\Microsoft\VisualStudio\10.0\Extensions\Microsoft\”下，路径规则同其余模板；

3、再次安装VS插件，新插件会覆盖第二步手动建立的文件，从而能够修改的“ClaimsAwareASPNETSite.webproj”文件；

4、打开该文件，按英文描述，去除第二行末尾的空格；

5、重启VS2010，再次使用此模板，问题解决，模板ClaimsAware网站可建立成功。

PS：建立Claims-aware WCF Service时也会遇到一样问题，解决办法相似。
