Why Can't I Connect to MySQL with Entity Framework 6?

Unable to Establish MySQL Connection with Entity Framework 6

While attempting to utilize Entity Framework 6 with MySQL, an issue arises when creating a new ADO.NET Entity model. Despite installing MySQL plugin and connector, MySQL remains unavailable as a connection option.

Investigation

It is determined that this is a known bug related to MySQL. Specifically, it affects users attempting to connect Entity Framework 6 with MySQL Connector .NET 6.8.3 and MySQL for Visual Studio plugin 1.1.3.

Workaround

A workaround is available to resolve this issue. Navigate to the MySQL Connector .NET binary installation folder (typically "C:Program Files (x86)MySQLMySQL Connector Net 6.8.3Assembliesv4.5"). Locate the "MySql.Data.Entity.EF6.dll" file and copy it to the following path: "C:Program Files (x86)Microsoft Visual Studio 12.0Common7IDEPrivateAssemblies".

Additional Steps for Resolve Entity Framework 6 Issue with MySQL

  • Install MySQL for Visual Studio 1.1.3.
  • Install MySQL Connector .NET 6.8.3.
  • Copy the following DLLs to the MySQL Connector Net installation folder:

    • MySql.Data.dll
    • MySql.Data.Entity.EF6.dll
    • MySql.Web.dll
  • Update the web config file with the following:
<entityFramework codeConfigurationType="MySql.Data.Entity.MySqlEFConfiguration, MySql.Data.Entity.EF6">
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6" /> 
    </providers>
  </entityFramework>

Resolution

By following these steps and rebuilding the solution, it should be possible to establish a MySQL connection within Entity Framework 6.

What is GTID (Global Transaction Identifier) and what are its advantages? What is GTID (Global Transaction Identifier) and what are its advantages? Jun 19, 2025 am 01:03 AM

GTID (Global Transaction Identifier) ??solves the complexity of replication and failover in MySQL databases by assigning a unique identity to each transaction. 1. It simplifies replication management, automatically handles log files and locations, allowing slave servers to request transactions based on the last executed GTID. 2. Ensure consistency across servers, ensure that each transaction is applied only once on each server, and avoid data inconsistency. 3. Improve troubleshooting efficiency. GTID includes server UUID and serial number, which is convenient for tracking transaction flow and accurately locate problems. These three core advantages make MySQL replication more robust and easy to manage, significantly improving system reliability and data integrity.

What is a typical process for MySQL master failover? What is a typical process for MySQL master failover? Jun 19, 2025 am 01:06 AM

MySQL main library failover mainly includes four steps. 1. Fault detection: Regularly check the main library process, connection status and simple query to determine whether it is downtime, set up a retry mechanism to avoid misjudgment, and can use tools such as MHA, Orchestrator or Keepalived to assist in detection; 2. Select the new main library: select the most suitable slave library to replace it according to the data synchronization progress (Seconds_Behind_Master), binlog data integrity, network delay and load conditions, and perform data compensation or manual intervention if necessary; 3. Switch topology: Point other slave libraries to the new master library, execute RESETMASTER or enable GTID, update the VIP, DNS or proxy configuration to

How to connect to a MySQL database using the command line? How to connect to a MySQL database using the command line? Jun 19, 2025 am 01:05 AM

The steps to connect to the MySQL database are as follows: 1. Use the basic command format mysql-u username-p-h host address to connect, enter the username and password to log in; 2. If you need to directly enter the specified database, you can add the database name after the command, such as mysql-uroot-pmyproject; 3. If the port is not the default 3306, you need to add the -P parameter to specify the port number, such as mysql-uroot-p-h192.168.1.100-P3307; In addition, if you encounter a password error, you can re-enter it. If the connection fails, check the network, firewall or permission settings. If the client is missing, you can install mysql-client on Linux through the package manager. Master these commands

How does InnoDB implement Repeatable Read isolation level? How does InnoDB implement Repeatable Read isolation level? Jun 14, 2025 am 12:33 AM

InnoDB implements repeatable reads through MVCC and gap lock. MVCC realizes consistent reading through snapshots, and the transaction query results remain unchanged after multiple transactions; gap lock prevents other transactions from inserting data and avoids phantom reading. For example, transaction A first query gets a value of 100, transaction B is modified to 200 and submitted, A is still 100 in query again; and when performing scope query, gap lock prevents other transactions from inserting records. In addition, non-unique index scans may add gap locks by default, and primary key or unique index equivalent queries may not be added, and gap locks can be cancelled by reducing isolation levels or explicit lock control.

What are the transaction isolation levels in MySQL, and which is the default? What are the transaction isolation levels in MySQL, and which is the default? Jun 23, 2025 pm 03:05 PM

MySQL's default transaction isolation level is RepeatableRead, which prevents dirty reads and non-repeatable reads through MVCC and gap locks, and avoids phantom reading in most cases; other major levels include read uncommitted (ReadUncommitted), allowing dirty reads but the fastest performance, 1. Read Committed (ReadCommitted) ensures that the submitted data is read but may encounter non-repeatable reads and phantom readings, 2. RepeatableRead default level ensures that multiple reads within the transaction are consistent, 3. Serialization (Serializable) the highest level, prevents other transactions from modifying data through locks, ensuring data integrity but sacrificing performance;

What are the ACID properties of a MySQL transaction? What are the ACID properties of a MySQL transaction? Jun 20, 2025 am 01:06 AM

MySQL transactions follow ACID characteristics to ensure the reliability and consistency of database transactions. First, atomicity ensures that transactions are executed as an indivisible whole, either all succeed or all fail to roll back. For example, withdrawals and deposits must be completed or not occur at the same time in the transfer operation; second, consistency ensures that transactions transition the database from one valid state to another, and maintains the correct data logic through mechanisms such as constraints and triggers; third, isolation controls the visibility of multiple transactions when concurrent execution, prevents dirty reading, non-repeatable reading and fantasy reading. MySQL supports ReadUncommitted and ReadCommi.
