Cannot add connection to MySQL in C# application - c#

I am trying to connect MySQL to Windows following the instructions given here.
I have installed MySQL 5.1 software, GUI tools and MySQL connector. MySQL is working fine.
I want to establish connection between the MySQL database and a C# Windows application.
But I am not able to find "MySql.Data" in add references tab in the C# Windows application. Can anyone help me to solve this issue?
Please refer to the screenshot below:

If you really have the Connector/NET installed, it ought to show up in the .NET tab.
If not you can just click the Browse tab, and add the assembly directly, it should be under
C:\Program Files\MySQL\MySQL Connector
Net 6.0.4\Assemblies
or somesuch.

How about browsing to the DLL (browse tab)?

Error trying to connect a firebird database with ODBC or C# application

I'm trying to connect my c# application in a Firebird database. Using the user and password I got works on firebird sql tool. But when I go to my c# app, I got an error.
So I went to the ODBC drivers, trying to connect and I got the same error.
Here is the odbc screen
And here is the error
Like I said, it really works with firebird ISQL tool.
I already changed a few configs into the firebird.conf file.
I had to set
WireCrypt = Enabled
for resolve a previously problem, and now I'm trying this one but without success
AuthServer=Srp,Legacy_Auth
Any help guys? Thanks in Advance!
EDIT
The error in C# application is exactly the same of ODBC.
Stacktrace:
at FirebirdSql.Data.Client.Managed.GdsConnection.Identify(String Database)
at FirebirdSql.Data.FirebirdClient.ClientFactory.CreateManagedDatabase(FbConnectionString options)
at FirebirdSql.Data.FirebirdClient.ClientFactory.CreateDatabase(FbConnectionString options)
at FirebirdSql.Data.FirebirdClient.FbConnectionInternal.Connect()
FirebirdSql.Data.FirebirdClient
5.11.0.0
Server version
I`m not referencing fbclient.dll yet!
But I have it after install the Firebird. The version is
3.0.2.32703
Thanks for now!
I solved my problem by just going to Firebird folder (windows explorer) and changing the security for everyone (full permission to everyone). So my app and odbc started working.
I'm sure it's not the right way but I solved my problem for now.
Waiting for better answers.

How do I connect to an mysql database in Visual Web Developer 2010?

It was my understanding that I should install the "ADO.NET Driver for MySQL (Connector/NET)", but it doesn't integrate with Visual Web Developer 2010, so I can't select a mysql-connection when creating a new connection from the Database Explorer.
There was VS 2008 Express installed and it configured it under installation. So I uninstalled VS 2008 Express and reinstalled the mysql connector without luck. Then I installed VS 2010 Express, but it didn't integrate there either.
Does anyone know what is wrong? How can I connect to an mysql database from Visual Web Developer 2010?
The ADO driver doesn't seem to integrate with Visual Web Developer Database explorer. You can however make a connection to a MySQL database by using ".Net Framework Data Provider for ODBC". You need to add a dsn reference first. Go to the Control Panel, go to Administration Tools and select Data Sources (ODBC). I added an User DSN by press the Add button. You should fine the MySQL ODBC 5.1 Driver in the list. Select it and you'll get the MySQL Connector/ODBC Data Source Configuration dialog box. Give a name to you Data Source Name (what ever you wnat to call it). Select TCP/IP Server. The server name was left blank since its on my local machine and the port was 3306. Enter the administrative user name the you used when you install MySQL for the User and enter the Password you used. You can then select the database you want. Assuming you installed the sample database, You'll see your database and the sample database in the drop down list. You can then press the Test button and it will verify that you can verify that the database connection works. Once you have that done you can my add a connection to you MySQL database in the Database Explorer by again selecting the ".Net Framework Data Provider for ODBC" You do that by changing the datasoure which bings up a Datasource dialogue box. Then select ".Net Framework Data Provider for ODBC" for the data provider.
In order to program and use mySQLConnection uou need to a a reference to it in Visual Web Developer 2010. To add the reference, click on the menu "Website" and select "Add reference ...". This will bring up the Add Reference dialog box. You would think that the refence would be available in the ".Net" tab, but it isn't. You need to select the "Browse" tab and an navigate to the the MySql assemblies. For me they were located in "C:/Program Files/MySQL/MySQL Connector Net 6.4.3/Assemblies./v4.0. By holding the "shift" or "ctrl" key down you can select all three dll's which are named" MySql.Data.dll, MySql.Data.Entity.dll and MySqlWeb.dll.
I am pretty sure you can use an ODBC connection to accomplish this, you just need to make sure you have the driver installed.

MySQL client portability for my C# app

I am building an application which needs to connect to a central MySQL database. The application is written in C#. I have installed the .NET connector from MySQL for the VS integration.
I was wondering if there is anything special I need to do to be able to have my application be portable and not require an install of the connector on every machine it is used on?
There is a similar question I found here on SO, but it is for a server instead instead of client which is very different.
Edit:
Connector I used: .NET connector 6.2.3 (
http://www.mysql.com/downloads/connector/net/)
When you make an installer, you can include the dll for the mysql connecter such that it is copied along with the other side. This way, whenever the application is installed properly, you wont have the problem.

C# MySQL Connector works in IDE, not after publish?

For some reason I can't seem to get the MySQL Net Connector to work with C# outside of the IDE. I have a very simple program working just fine in the IDE (connecting to the database and everything) but when I publish the code and run the .application file (on my local computers desktop or off the company server) it says it can't connect to any of the specified MySQL hosts.
Any help would be greatly appreciated! :(
Thank you
I would double check all your references, and make sure you have the MySQL Net Connector in the GAC.
Check that the MySQL provider is properly declared in the machine.config file (in the DbProviderFactories element). You can also declare it in the web.config instead

Including MySQL Connector/ODBC 5.1 to C# application

I am using System.data.odbc with "Driver={MySQL ODBC 5.1 Driver}" in the connection string. However, I have not realised there is MySQL connector installed on my PC so however I have not referenced it, it doesn work without it.
Now I need to distribute it embed in the app. I have downloaded MySQL Connector/ODBC 5.1 files, but with Add reference it says "The file is not accessible...make sure its valid COM.." etc.
Thank you
MySQL Connector/ODBC is, as the name suggests, just an ODBC driver for connecting to MySQL. It's not specifically designed for .NET and you can't embed it in your .NET applications in any way. It will need separate installation on any machine where you need to use it.
MySQL Connector/Net is a fully managed ADO.NET provider for MySQL. It's tailor-made for .NET and doesn't require the installation of any other software. It's easy to reference and distribute in your .NET applications, you'll just need to use the System.Data.MySqlClient namespace and objects rather than System.Data.Odbc.
You can embed the .NET DLL, but not the driver itself. You'll need to install MySQL Connector on every computer that runs your application.
The only thing u need is Mysql.Data.Dll
You don't need to install the complete connector, everything u need is in there.
That also counts for the end user, they also only need the dll
