long-term listener, first time caller!
I am trying to connect to MySQL using the ADO.NET Entity Framework. (Visual Studio 2010, .NET 4.0) I created a web project and another class library project that will serve as my DAL. I have no problems on my local machine, and I also tried to work with average trust. Im able to fully control db as expected.
However, when I deploy to my host (general, medium trust), I keep getting errors. I changed my web.config in several ways: Ive explicitly named my assembly in the connection string, Ive used wildcard matching, added links to MySQL dlls, etc.
<connectionStrings>
<add name="NamespaceContext" connectionString="metadata=res:// Namespace.Data.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null/DataModel.csdl|res:// Namespace.Data.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null/DataModel.ssdl|res:// Namespace.Data.Model, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null/DataModel.msl;provider=MySql.Data.MySqlClient;provider connection string="server=myserver;User Id=user;database=thedatabase;password=password;Persist Security Info=True"" providerName="System.Data.EntityClient"/>
<add name=" NamespaceContext " connectionString="metadata=res://*/;provider=MySql.Data.MySqlClient;provider connection string=" server=myserver;User Id=user;database=thedatabase;password=password;Persist Security Info=True"" providerName="System.Data.EntityClient"/>
<add name=" NamespaceContext " connectionString="metadata=res://*/DataModel.csdl|res://*/DataModel.ssdl|res://*/DataModel.msl;provider=MySql.Data.MySqlClient;provider connection string=" server=myserver;User Id=user;database=thedatabase;password=password;Persist Security Info=True"" providerName="System.Data.EntityClient" />
</connectionStrings>
The error I get is:
System.ArgumentException: The specified store provider cannot be found in the configuration, or is not valid. --->
System.ArgumentException: Unable to find the requested .Net Framework Data Provider. It may not be installed.
