요청한 .Net Framework 데이터 공급자를 찾을 수 없습니다. 그것은 설치되지 않을 수도 있습니다

Question

나는 visual studio 2015에서 EntityFramework를 사용하고 있습니다. webmatrix SimpleMembership을 구현하려고합니다. 하지만 "요청 된 .Net Framework 데이터 공급자를 찾을 수 없습니다. 설치되지 않았을 수 있습니다."라는 오류 메시지가 나타납니다.

이 내 컨트롤러에 있습니다

[HttpGet] 
public ActionResult Register() 
{ 
    string conn3 = Path.Combine("Data Source=(localdb)","MSSQLLocalDB;Initial Catalog=projekt.Models.KnjiznicaKontekst;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=True;ApplicationIntent=ReadWrite;MultiSubnetFailover=False"); 

    if (!WebSecurity.Initialized) 
    { 
     WebSecurity.InitializeDatabaseConnection(conn3, "projekt.Models.KnjiznicaKontekst", "Uporabniks", "idUporabnik", "email", autoCreateTables: true); 
    } 
    return View(); 
}

내가 먼저 엔티티 프레임 워크 코드를 사용하고 있는데의 Web.config에는 연결 문자열이 없다 하지만 데이터베이스의 속성에서 실제 연결 문자열을 복사했습니다. Websecurity.InitializeDatabaseConnection()이 실행을 시도하면 오류가 발생합니다.

도움 주셔서 감사합니다.

Answer 1

나는 문제를

WebSecurity.InitializeDatabaseConnection(conn3, "projekt.Models.KnjiznicaKontekst", "Uporabniks", "idUporabnik", "email", autoCreateTables: true);

대신 "projekt.Models.KnjiznicaKontekst는"이이 경우 "의 System.Data.SQLClient"입니다 제공자 이름이 필요의 발견!
