使用同步到 mysql 服务器的 MVC4。通过更改 machine.config 成功并成功使用 ASP.net 配置工具创建用户。但是，当我使用使用该工具创建的用户名(并且在数据库中)登录时，出现此错误

这是一个全新的数据库，带有来自 VS2010 的全新 MVC4 Razor 网站。有什么想法吗？

最佳答案

Asp.Net MVC 简单成员资格与普通 Web 表单成员资格提供程序不同。检查以下 blog post .来自链接文章

• SimpleMembership 与以前的成员(member)系统集成，但您不能将 MembershipProvider 与 SimpleMembership 一起使用
• ASP.NET 4.5 Web 窗体不使用 SimpleMembership；它在 ASP.NET 成员资格之上实现 OAuth

另见下图:

异常(exception)，据了解您的提供商是classic membership provider并且它与简单成员(member)资格不兼容。

"Membership.Provider" property must be an instance of "ExtendedMembershipProvider".

可以看下post1 , post2适用于 MySql 兼容的 Asp.Net MVC 简单成员(member)提供程序。

关于c# - asp.net 问题中 mysql 的 Membership.Provider，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16635188/
