I am currently developing a project in MVC3 Visual Studio 2012. I am connecting to an external database but when I try to add a new controller I get this error.
Unable to retrieve metadata for 'Project.Models.Class'. Unable to find the requested .Net Framework Data Provider. It may not be installed.
I cannot figure out why it can't find my .Net Framework Data provider. I have altered the two machine.config files I can find, and they now look like this.:

</connectionStrings>

I have of course censored some information for security purposes but that is the basic layout.
Can anyone see an error I cant? or has any idea why this may be happening? Any help would be greatly appreciated.

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"

</DbProviderFactories>
</system.data>
<dataConfiguration defaultDatabase="db1"></dataConfiguration>
<connectionStrings>

</connectionStrings>

</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>
Attempting to run integration tests in a project using Entity Framework 6 resulted in the error:
SetUp : System.NotSupportedException : Unable to determine the provider name for provider factory of type
'System.Data.SqlClient.SqlClientFactory'. Make sure that the ADO.NET
provider is installed or registered in the application config.
But the tests on same project works absolutely fine on several of my colleagues' machines and I have no local changes.
Have attempted reinstalling EF, I don't have any unnecessary config sections or Glimpse and I've tried targeting a different version of the framework but the error persists...
It turns out I have an empty, duplicate DbProviderFactories element in both my Framework/Framework64 machine.config files, which appears to have been created by the installation of the IBM DB2 .NET provider (?!). The duplicate node is rendering the machine.config invalid, so the issue is localised to my machine.
Modifying

Resolved the issue.
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"

</DbProviderFactories>

I am currently working on a 3.5 .NET C# Project. it uses an external program that takes an argument when I build and run it. The external program goes to index a structured or an unstructured source of data.
The C# project is a simple .dll that override some of the external program methods. At the initialization part, I do request a connection to my postgreSQL DB in order to get back a unique ID.
WARNING : Indexer and my DB have no link, Indexer can index folder with .xls files, or mysql DB. My PostgreSQL is here just to bring a unique ID and store some important informations
My problem is when I launch as an external program the DBConnector which is a 32 bit indexer, everything goes well.
Whereas when I launch the AlfrescoConnector which is a 64 bit indexer, I can't open my postgreSQL database.
I put the x86 & x64 type of connector but I don't know if the problem comes from there.
I'm working on Visual 2012, my debug is set to produce a x86 compatible program (changing it to "any CPU" or "x64" doesn't solve the problem)
The db object I use is DbClient which is a specific method that you won't find on the internet because it comes from the external program reference, but it works as a classic DbConnector.
My DbClient object looks like this :
dbClient = {Sinequa.Common.DbClient}
_CurrentTransaction = null
ConnectionString = "Server=localhost;Port=5444;User Id=USERSAMPLE;Database=DBSAMPLE;Password=PWDSAMPLE;"
DbCn = null
DbCnSubSelect = null
DbFactory = null
DbIsolationLevel = Unspecified
DefaultCommandBehavior = SequentialAccess
Engine = Postgres
Error = 0
ErrorText = null
LastRowAffected = 0
LOBFetchSize = 0
Provider = "Npgsql"
RefreshCount = 0
RefreshCurrent = 0
Schema = null
The error comes when I do myDbClient.Open() with the Alfresco one
Any suggestions ? Need more details ? I'm ready to solve this painful error with you my fellows !
The Alfresco x64 bit connector use the x64 bit of the .NET configuration file. The configuration files located at:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\machine.conf
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config\machine.conf
C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG\machine.conf
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.conf
Remember that the problem is the missing provider. So to solve this problem you have to insert the lacking provider between the DbProviderFactories tag like this:
<DbProviderFactories>
<add name="Odbc Data Provider" invariant="System.Data.Odbc" description=".Net Framework Data Provider for Odbc" type="System.Data.Odbc.OdbcFactory, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>

<add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.5.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"/>
<add name="Microsoft SQL Server Compact Data Provider 4.0" invariant="System.Data.SqlServerCe.4.0" description=".NET Framework Data Provider for Microsoft SQL Server Compact" type="System.Data.SqlServerCe.SqlCeProviderFactory, System.Data.SqlServerCe, Version=4.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"/>
</DbProviderFactories>
With this insert the next time the DbClient will try to open the Database and get the asked provider, it will succeed.
I don't know who else to ask for help.
Here in my company we are migrating the system. 2.0 to 3.5 net
We use enterprise library 3.1 and we are migrating to 5.0
I used the tool for configuration file
The compilation was ok but when I run, i receive this message:
Activation error occured while trying to get instance of type Database, key "MrvFramework"
Resolution of the dependency failed, type = "Microsoft.Practices.EnterpriseLibrary.Data.Database", name = "MrvFramework".
Exception occurred while: while resolving.
Exception is: InvalidOperationException - The type Database cannot be constructed. You must configure the container to supply this value.
At the time of the exception, the container was:

I spent a lot of time on internet:
I had made this tests:

var database = DatabaseFactory.CreateDatabase(MrvFramework)
var database = EnterpriseLibraryContainer.Current.GetInstance<Database>(MrvFramework)
var database = new SqlDatabase(MrvFramework)
This is my app.config (snippet-code)
