MySql connector/net 6.0 alpha has been released

MySQL Connector/Net 6.0.0, a new version of the all-managed .NET driver for MySQL has been released.  This is an alpha release and is intended to introduce you to the new features and enhancements we are planning.  This release should not be used in a production environment.

We had three major goals with this release.  Speed, Entity Framework support, and a better Visual Studio experience.  I'm happy to report that we have met all three.  Please see the complete list of changes below.

It is now available in source and binary form from [http://dev.mysql.com/downloads/connector/net/6.0.html] and mirror sites (note that not all mirror sites may be up to date at this point of time - if you can't find this version on some mirror, please try again later or choose another download site.)

  • Massive speedups.  We have increased the speed of the provider.  In many situations it now matches or exceeds the speed of the native C connector.
  • SQL tokenizing has been improved dramatically.  Not only is it substantially faster (approx 40%) it also now uses a completely rewritten tokenizer that supports all types of stored procedure comments.
  • Added UDF schema collection
  • Implement initial Entity Framework support (see below)
  • Improved Visual Studio integration (see below)


Entity Framework support
Yes, we are late to the party but we are here.  I apologize for the delays related to this release and I hope that those of you looking to use MySQL with the entity framework will still want to give us a look.  This releases uses a entity framework engine that was completely developed in-house and is, therefore, licensed in exactly the same way as our core provider.  Please remember that this is an alpha release and we are certain that you will find databases that will not reverse-engineer correctly or you will build models or queries that will not generate correctly. Please file those as bug reports and include all the information you can.  We'll quickly get to those as we are going to move as quickly as possible to GA.

Visual Studio improvements
Even though these improvements did not make the cutoff for this alpha, you will see them in the next drop.  We have completely rewritten our Visual Studio integration bits and are delivering several exciting features with it.  Here's a look at some of those features:
1.  Now uses the same toolbars and commands as SQL Server so the integration is much more seamless.
2.  Uses the native code editor which means code splitting and syntax highlighting.
3.  Change script generation
4.  And many more smaller features.....

Please take this version for a test drive and let us know what works and what doesn't.

    hello

    I'm using MySQL And "MySQL Connector Net 6.0.0" - I've updated "my.ini" (I ran into packet too large exception) as follows:
    Code:

    max_allowed_packet = 32M


    I think I hear they say you'd also need to make corresponding change on client side - the C# app uses MySQL .NET Connector 6.0 and I checked doc and www.connectionstrings.com on connection string format, it seems to be that you can't set max packet size in connection string? Is this true?

    When one takes a look at the amount of code that the average application developer must write to address the impedance mismatch across various data representations (for example objects and relational stores) it is clear that there is an opportunity for improvement. Indeed, there are many scenarios where the right framework can empower an application developer to focus on the needs of the application as opposed to the complexities of bridging disparate data representations

  7. Every business application has, explicitly or implicitly, a conceptual data model that describes the various elements of the problem domain, as well as each element's structure, the relationships between each element, their constraints, and so on.

    Since currently most applications are written on top of relational databases, sooner or later they'll have to deal with the data represented in a relational form. Even if there was a higher-level conceptual model used during the design, that model is typically not directly "executable", so it needs to be translated into a relational form and applied to a logical database schema and to the application code.

    While the relational model has been extremely effective in the last few decades, it's a model that targets a level of abstraction that is often not appropriate for modeling most business applications created using modern development environments.

  11. ive been playing arount with the EF support now and i gotta say, it works pretty good :)
    the only issues ive really run into are because if EF it self (for example that you havee to explicitly call Load on associations for them to get loaded and that you have to remove fields from entites that are also used in associations)

    We use GNU Autoconf, so it is possible to port MySQL to all modern systems that have a C++ compiler and a working implementation of POSIX threads. (Thread support is needed for the server. To compile only the client code, the only requirement is a C++ compiler.)

    Hi,
    Quality is a word that a lot of people like to use when describing their web design services. But what is quality, how do you know if a design is quality or not. Well, I think that there’s quite a few ways to spot quality within web designs. Once you can see just what goes into making a quality web design, you can use the techniques to perfect your own style.
