Beim Ausführen unseres MVC4-Projekts mit Azure Mysql DB wird der folgende Fehler angezeigt.

In Datei Web.Config wir folgendes haben,

<DbProviderFactories> 
     <remove invariant="MySql.Data.MySqlClient" /> 
     <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data" /> 
</DbProviderFactories>

Answer 1

Stellen Sie sicher, MySql hinzugefügt haben. Data.Entity.dll & MySql.Data.dll Dateien in den Papierkorb des Projekts MVC

Answer 2

Wenn Mono verwenden, stellen Sie sicher, dass Sie auch MySQL Data Provider-Knoten in machine.config haben. Ich bin mit 4,5 so für mich es ist /opt/mono/4.5/machine.config (zB Standort):

<system.data> 
    <DbProviderFactories> 
     <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> 
    </DbProviderFactories> 
</system.data> 

Sie machine.config Lage, indem Sie einfachen Befehl in Linux finden:

cd/&& find -name 'machine.config' 

Sie müssen sudo vor find Befehl auf Ubuntu:

cd/&& sudo find -name 'machine.config'
