MSLinqToSQLGenerator在VS2008中失败。 [英] MSLinqToSQLGenerator failed in VS2008.
问题描述
当我尝试添加新项目时，我收到以下错误（Linq to SQL Classes）：
"错误1自定义工具'MSLinqToSQLGenerator'失败。对象引用未设置为对象的实例。"
我在Beta 2中遇到此错误（不是最初虽然）。
我卸载了Beta 2并安装了RTM Visual Studio 2008，但同样的错误不断出现。
修复RTM是没用的。
然后我卸载RTM并重新安装，但这也无济于事。
当我在VS2008中打开现有的dbml文件时，没有错误，但是文件是在XML编辑器中打开而不是'MSLinqToSQLGenerator'编辑。
我想编辑器和文件类型之间的链接已经消失了。
当我打开菜单项Tools / Options / Database tools / O / R designer时，右窗格不会显示，只显示"加载此属性页面时出错"。显示。
如何重新创建链接？
亲切的问候，

你卸载了*所有*吗？添加/删除程序[Vista中的程序和功能]中有很多与Visual Studio相关的条目，您应该将它们全部删除。

Hi,
I'm getting the following error when I try to add a new item (Linq to SQL Classes):
"Error 1 The custom tool 'MSLinqToSQLGenerator' failed. Object reference not set to an instance of an object."
I got this error in Beta 2 (not initially though).
I de-installed Beta 2 and installed the RTM Visual Studio 2008, but the same error keeps appearing.
Repairing RTM was of no use.
I then de-installed RTM and re-installed again, but this didn't help either.
When I open an existing dbml file in VS2008, there is no error, but the file is opened in an XML editor in stead of the 'MSLinqToSQLGenerator' editor.
I suppose the link between the editor and the filetype is gone.
When I open the menu item Tools / Options / Database tools / O/R designer, the right pane is not displayed, only "An error occurred loading this property page" is displayed.
How can I recreate this link?
kind regards,
Karel Vandenhove
Did you uninstall *everything*? There are a lot of entries in Add/Remove Programs [Programs and Features in Vista] that are related to Visual Studio, and you should remove them all.
