Question

我在没有Websecurity的情况下测试了数据库连接，但它确实有效。我遵循了Brice Lambson http://brice-lambson.blogspot.com.es/2012/10/entity-framework-on-postgresql.html

的教程

但是当我使用

时

WebSecurity.InitializeDatabaseConnection（ “myContext”， “UserProfile”，“UserId”，“UserName”，autoCreateTables：false）;

我得到了这个例外：

            in WebMatrix.WebData.SimpleMembershipProvider.ValidateUserTable()

我想NpgSql无法准备使用SimpleMerbership，但我想知道你是否有人试过这个。谢谢!!

Answer 1

你应该尝试Daniel Nauck的AspSQLProvider：http://dev.nauck-it.de/projects/show/aspsqlprovider

它是ASP.NET 2.0+成员，角色，配置文件和会话状态存储提供程序的PostgreSQL实现。

我希望它有所帮助。

Answer 2

我暗示您尝试将“autoCreateTables：false”更改为“autoCreateTables：true”。

Answer 3

不适用于postgres，因为它在整个嵌入式SQL中注入括号（[...]）：

PostgreSQL + Npgsql连接器+ MVC和SimpleMembership不工作
