这个问题已被问过几次，但从未得到过回答，所以希望我们现在能够得到答案。
我有一个现有项目，其中包含许多合同类和EF6数据访问项目，这些项目都来自我的MVC5 Web项目。
我想使用glimpse，所以我在我的MVC web项目上安装了一瞥。
然而，在这样做之后，我不断收到以下错误：
无法确定类型的提供程序工厂的提供程序名称 'System.Data.SqlClient.SqlClientFactory'。确保ADO.NET provider已在应用程序配置中安装或注册。
当我卸载一瞥时，一切都有效。现在做了一些谷歌搜索后，似乎这是一个问题，但我找不到任何人用一个确定的答案解决它，并且我尝试过的每一个建议都没有修复它。
在我还在使用EF5之前，我已经安装了一瞥，这一切都没有任何问题，但是自从搬到EF6后我没有运气。
希望这是一个我缺少的小配置。
感谢任何帮助。
