Hi I started building apps with this technology and I am facing a weird problem... on some machines I need to add theese lines to the app.config to get to work:
<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=6.3.0.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
while in other machines it runs well without theese lines.... the thing is that when I add theese lines the app wont run on machines that did not needed theese lines in the firs place, and I would like not to publish to versions of the app, is there a way to solve this?
Any Help would be appreciated!!!
Would post as comment but i can't yet.**
It could be your machine.configs are different. I would check to make sure your DbProviderFactories are registered consistently in the machine.config.
Did you try removing it?
<system.data>
<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, Version=6.3.0.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>

I seem to be having issues when using MySQL to connect to an existing DB. I am using Entity Framework and using it to read from a current Database.
When I go and visit a page to load info up, I get the following error
System.InvalidOperationException: 'The Entity Framework provider type 'MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity' registered in the application config file for the ADO.NET provider with invariant name 'MySql.Data.MySqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.'
My web.config:
<entityFramework>
<defaultConnectionFactory
type="MySql.Data.Entity.MySqlConnectionFactory, MySql.Data.Entity.EF6" />
<providers>
<provider invariantName="MySql.Data.MySqlClient"
type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity" />
</providers>
</entityFramework>
<system.data>
<DbProviderFactories>
<remove invariant="MySql.Data.MySqlClient" />
<add description=".Net Framework Data Provider for MySQL"
invariant="MySql.Data.MySqlClient" name="MySQL Data Provider"
type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.10.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
Help appreciated in advance
I am use Database MySQL in ASP.NET c# application.When I use simple Steps for connect the MySQL database and create ADO.NET connections working fine. But I want to use Microsoft Enterprise Library for my application.I added Reference given below
Microsoft.Practices.EnterpriseLibrary.Common
Microsoft.Practices.EnterpriseLibrary.Data
Microsoft.Practices.EnterpriseLibrary.Data.S
MySql.Data
MySql.Web
Below is my web.comfig code
<system.data>
<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, Version=6.4.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
<dataConfiguration defaultDatabase="db1"></dataConfiguration>
<connectionStrings>
<add name="constr" connectionString="Server=localhost;Database=db1;user id=test;persistsecurityinfo=True;" providerName="MySql.Data.MySqlClient;"/>
</connectionStrings>
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" />
</configSections>
and when I use in code by below code
if (_connectionMode == DatabaseConnectionMode.UseConnectionStringName)
{
_Database = new DatabaseProviderFactory().Create(_dbConnectionString) as Database;
}
here throw the below error
The requested database db1does not have a valid ADO.NET provider name set in the connection string.
Give me proper solution with reason why this happening.
Your connection string name needs to match the default database:
<dataConfiguration defaultDatabase="db1"></dataConfiguration>
<connectionStrings>
<add name="db1" connectionString="Server=localhost;Database=db1;user id=test;persistsecurityinfo=True;" providerName="MySql.Data.MySqlClient;"/>
</connectionStrings>
I'm using Entity Framework 5.0 with MySQL 6.8.3
I've already copy both MySql.Data.dll and MySql.Data.Entity.dll to Output folder.
On my PC, I add following code to App.Config:
<system.data>
<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>
</system.data>
It works fine, but when I bring it to another PC, I must remove that config to make it worked. How can I make it worked without adding or removing that config?
I've figured out my problem. This issue was due to conflict of MySQL in project and Connector/Net.
For anyone has the same problem with me, just specific the version of MySQL dll in your provider configuration:
<system.data>
<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, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
</DbProviderFactories>
</system.data>
This version should be same as the dll that your project references.
I'm new on this. I got a sample project that runs perfectly on another pc but get an error when running on my own pc. I changed the connection string and restored the database only. I am using a SQLServer connection, but when I run the project it shows a MySQLRoleProvider error. I searched web.config for this configuration but it isn't there. How can I solve this issue?
The message:
`Parser Error Message: Could not load file or assembly 'MySql.Web, Version=6.7.4.0, Culture=neutral, PublicKeyToken=+++' or one of its dependencies.
<add name="MySQLRoleProvider"
type="MySql.Web.Security.MySQLRoleProvider, MySql.Web, Version=6.7.4.0, Culture=neutral, PublicKeyToken=***"
connectionStringName="LocalMySqlServer"
applicationName="/"/>`
You need to install the MySQL Connector binaries first for this to work.
http://dev.mysql.com/downloads/connector/net/
If after installation you still face problems, verify that the dll's are declared in machine.config file of the framework version that you're running.
Add following to config file...
<configuration>
<!--Other omited-->
<system.data>
<DbProviderFactories>
<clear />
<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient"
description=".Net Framework Data Provider for MySQL"
type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data,
Version=6.6.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" />
</DbProviderFactories>
</system.data>
<!--Other omited-->
</configuration>
I have a Winform application and am using EntityFramework. The application runs just fine in my dev machine but when I try to run at client's machine I get "The specified store provider cannot be found in the configuration, or is not valid" error. I have distributed EntityFramework.dll with the client. Why am I getting this error? I am not putting the connection strings in the app.config file as it is dynamically created based on the database selected at runtime.(I am using VistaDB as database)
The app.config is below:
<configuration>
<configSections>
<section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection,EntityFramework, Version=4.4.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
</configSections>
<connectionStrings>
</connectionStrings>
<entityFramework>
<defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
</entityFramework>
</configuration>
I had this problem. I uninstalled Connector .NET and reinstalled it. Now it works.
based on which type of DataBase you use you need to provide Db ORM settings that is going to used by Entityframe work
<system.data>
<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>
</system.data>
To solve this error, install Microsoft SQL Server Compact 4.0 on your client's computer.
