Windows 10 Pro
Visual Studio 2017 Pro - 15.5.6
MySQL for Visual Studio - 1.2.7
MySQL Connector/NET - 6.10.6.0
I have encountered an issue with MySQL for Visual Studio.
When opening the 'Configuring a Data Source' dialog box, and adding a query, I can query the data fine.
When running the Test Query on the final screen, it fails with the following error:
When finishing the configuration without testing the query, and subsequently running the debug - an Object Reference exception is thrown as shown below:
I have tested this on other solutions that previously worked, but I am getting the same issue.
Any ideas guys?
Fixed it. For anyone who is interested - I did the following:
Uninstalled MySQL for Visual Studio
Uninstalled MySQL Connector/Net
Re-Installed Latest Version for MySQL for Visual Studio
Installed Previous Version for MySQL Connector/Net (6.9.11)
Downgraded MySQL.Data to 6.9.11
Downgraded MySQL.Web to 6.9.11
There appears to be an issue with the latest version of Connector/NET.
I have posted this as a MySQL Connector/NET Bug.
This also occurs in VS2015 using anything over MYSQL for VS 1.2.4 and Connector/NET 6.9.8. When VS2017 was first released it worked with MYSQL but it breaks after making any changes to the MYSQL components, e.g upgrading to the latest GA release. I cannot remember the original configuration for the working VS2017. I have tried all combinations of MYSQL for VS and connectors but nothing has worked. Eventually I went back to 2015 because 1.2.4 does not support 2017. (Tried on both Windows 10 Home and Professional)
I suppose my answer is downgrade to VS2015, which is not really a fix.
I am new to MS Visual Studio & have downloaded & installed v2017 rc2.
I downloaded MySQL for Visual Studio, but even after a reboot, when I select Tools/Connect to database, I only see options for MS & Oracle, nothing for MySql.
Maybe it doesn't work with v 2017?
Actually, I just need a code a short command line program to run a SELECT and convert the result to CSV, so am open to any free IDE/Compiler solution for Windows 10.
MySQL for Visual Studio 2017 has only recently been released. More info at: https://dev.mysql.com/doc/visual-studio/en/visual-studio-install.html
I have installed the MySQL NET Connector 6.0 and am currently unable to get Visual Studio 2010 to recognize that the connector is installed. Is there a trick to do this with the beta connector?
The following are the steps I followed to try to connect Visual Studio 2010 with MySQL,
using MySql.Data.MySqlClient;
myConnectionString = "server=127.0.0.1;uid=root;" +
"pwd=12345;database=test;";
try
{
conn = new MySql.Data.MySqlClient.MySqlConnection(myConnectionString);
conn.Open();
}
catch (MySql.Data.MySqlClient.MySqlException ex)
{
MessageBox.Show(ex.Message);
}
Unfortunately, I still don’t get the required Data Sources,
I would appreciate if someone can tell me what I am doing wrong, or if I am missing any packages and how I can fix this problem.
Is the Connection string correct that you provided???First may be try to connect to server using VS2010 and test the connection
I have Microsoft Visual Studio 2010 (Ultimate) installed on my WINDOWS 7(32).
Here's what worked for me hope it'll help you too:
C# code:
SqlConnection myConnection = new SqlConnection(#"Data Source=DELL-PC\SQLEXPRESS;AttachDbFilename=|DataDirectory|Database.mdf;Integrated Security=True;User Instance=True;");
myConnection.Open();
Since SQL SERVER was preinstalled in the VS I did not go for connector software.
Find the SQLEXPRESS(if it's there) or try using compact preinstalled version
Change the machine name in the data source and database name as well.
i've installed mysql connector on my pc. But when i start Visual Web Developer 2010, i if i try to add a database server, i can't find and choose Mysql server.
I 've only Sql server, oracle and odbc driver.
I've tried to reinstall mysql connector (msi file downloaded via Mysql web site), but it not solve.
Does Anyone have the same problem ?
I've had this problem with a previous version of the mysql connector. The installer simply skipped to integrate with Visual Studio 2010. A newer release fixes this problem:
http://dev.mysql.com/downloads/connector/net/
I've found my problem: i was using visual studio express. Express seems not integrate mysql connector !
Thank you anyway for your answer!
According to MySQL they are not allowed by Microsoft to integrate with Express-editions of visual studio.

I use the MySQL Connector/Net to connect to my database by referencing the assembly (MySql.Data.dll) and passing in a connection string to MySqlConnection. I like that because I don't have to install anything.
Is there some way to "Choose Data Source" in Visual Studio 2010 without installing something?
How can I get a MySQL option (localhost) to show up on one of these lists? Or do I have to install something?
(I don't want to use ODBC btw)
"Add Connection" from Server Explorer:
Entity Data Model Wizard:
install the MySQL .NET Connector found here http://dev.mysql.com/downloads/connector/net/
"Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows."
Source: http://dev.mysql.com/downloads/connector/net/6.6.html
After a lot of searching and trying many solutions, I got it finally:
uninstall connector
uninstall MySQL for Visual Studio from control panel
reinstall them according to the table below
copy the assembly files from C:\Program Files (x86)\MySQL\MySQL Connector Net 6.9.8\Assemblies\v4.5 to C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE
log off and reopen your solution
enjoy
This seems to be a common problem. I had to uninstall the latest Connector/NET driver (6.7.4) and install an older version (6.6.5) for it to work. Others report 6.6.6 working for them.
See other topic with more info: MySQL Data Source not appearing in Visual Studio
Download MySQL Connector .NET (6.9.4 on this date) from here and install it CUSTOM!
Remove the ASP.NET WEB providers option or the installer will write in machine.config!
Download MySQL for Visual Studio from here and install it CUSTOM. Be sure to check the integration options. You need this step because after Connector .NET 6.7 the installer will no longer integrate the connector with Visual Studio. This installer can take longer then expected. This is it.
You can install it from alternate download here which should have integrated with VS correctly but it did not and I got a strange error and after the reinstall it is ok.
Visual Studio requires that DDEX Providers (Data Designer Extensibility) be registered by adding certain entries in the Windows Registry during installation (HKLM\SOFTWARE\Microsoft\VisualStudio\{version}\DataProviders) . See DDEX Provider Registration in MSDN for more details.
Installing the following packages:
Connector/NET 8.0.16: https://dev.mysql.com/downloads/connector/net/
MySQL for Visual Studio 1.2.8: https://dev.mysql.com/downloads/windows/visualstudio/
adds MySQL Database to the data sources list (Visual Studio 2017)
View ImageI have got the same problem for my vs 2013 on 64-bit machine. So i tried to download MySql extension for VS and install it on my machine. and restart the vs.
In order to get the MySQL Database item in the Choose Data Source window, one should install the MySQL for Visual Studio package available here (the last version today is 1.2.6):
https://dev.mysql.com/downloads/windows/visualstudio/
Right Click the Project in Solution Explorer and click Manage NuGet Packages
Search for MySql.Data package, when you find it click on Install
Here is the sample controller which connects to MySql database using the mysql package. We mainly make use of MySqlConnection connection object.
public class HomeController : Controller
{
public ActionResult Index()
{
List<employeemodel> employees = new List<employeemodel>();
string constr = ConfigurationManager.ConnectionStrings["ConString"].ConnectionString;
using (MySqlConnection con = new MySqlConnection(constr))
{
string query = "SELECT EmployeeId, Name, Country FROM Employees";
using (MySqlCommand cmd = new MySqlCommand(query))
{
cmd.Connection = con;
con.Open();
using (MySqlDataReader sdr = cmd.ExecuteReader())
{
while (sdr.Read())
{
employees.Add(new EmployeeModel
{
EmployeeId = Convert.ToInt32(sdr["EmployeeId"]),
Name = sdr["Name"].ToString(),
Country = sdr["Country"].ToString()
});
}
}
con.Close();
}
}
return View(employees);
}
}
I had the same problem and I solved it by uninstalling MySQL Connector for visualstudio and Mysql for visualstudio, (since I used version 2022 of visual studio I had to download version 2017, 2019 also supports it) and reinstalling the previous components and using a framework version for mysql (it is a bit annoying since sqlserver is simpler)
unfortunately this is not supported in the builtin tools in visual studio. however, you can create your own data provider using mysql connector but still have to integrate it from code
a) Visual Studio 2019 (connector for version 2022 does not exists)!
b) MySQL Installer Community 8.0.28 (not later)!
b) Clean installation - some configuration data stays from previous version (Program Files, Program Data, AppData, Registry, ...), and installer use it, so MySQL service sometimes freezes during installation.
c) MySQL 5 compatibility mode! No SHA caching option more!
No problems with login.
Tables are visible in VS connection guide.
No utf8mb3 | .NET Framework problem.
