I've got a pretty basic setup in Visual Studio 2008 - Website project referencing my class library project. SubSonic 3 is referenced from both projects, but the template has been modified for my MySQL db. It connects and generates the most of code (except for stored procedures, for some reason), and the namespace is there, and my intellisense picks it up while coding in the website project, I still get build errors saying that the namespace doesn't exist.
It's driving me crazy, and it know (hope) it's probably simple, but I've not had enough sleep to rationalize the problem. Any help would be incredibly appreciated!
Thank you in advance.

P.S. I've used SubSonic earlier versions, but never with MySQL.
Does the project reference the subsonic dll and the mysql .net connector?

I'm trying trying to build a web app with ASP.NET Core 3.0 and using VS Code to do it. Moreover, I'm using MySQL for my database, and this is where things are getting rough. It seems like there's very little support out there for this particular combination of VS Code and MySQL.
I can't find any tutorials with this particular combination, so I can't figure out how to put it all together. I ran the dotnet add package Mysql command, which installed the package, and I see that it's been added to the .csproj file, except now I don't know how to make use of it in my Model file. I'm trying to find the using directive for it, but I can't find any posts on any forums addressing this issue.
I've been searching for an example on how to connect to a MySql database and use F# type providers but I could not find anything online.
Can anyone give me a clue? What - if any - extra packages do I need? Do I use SqlDataConnection or SqlEntityConnection.
Excuse my ignorance but I'm totally lost. Any and all help is appreciated. I love the idea of type providers and have a fair amount of experience with functional programing but it's the setup around this that gets me.
I don't think there is out-of-the box type provider that would work with MySQL at the moment. However, Ross McKinlay has been working on a better type provider for SQL databases (more generally). It currently works with MS SQL server and SQL Lite.
It should be possible to write an extension to support MySQL with fairly small amount of work (but sadly, it has not been done yet). See his blog for details. I'm sure that contributions are welcome!
I haven't tested this, but if Entity Framework works with MySql (it does) and if F# has an Entity Framework Type Provider (it does) then I would expect the Entity Framework Type Provider to work with MySql.
Have you tried that approach?
If you are still interested, I recently added support for MySQL to my SQL type provider, help with testing would be good!
A general SQL database type provider, supporting LINQ queries, schema
exploration, individuals and much more besides.
The provider currently supports MS SQL Server, SQLite, PostgreSQL,
Oracle, MySQL and MS Access. All database vendors except SQL Server
and MS Access will require 3rd party ADO.NET connector objects to
function. These are dynamically loaded at runtime so that the SQL
provider project is not dependent on them. You must supply the
location of the assemblies with the "ResolutionPath" static parameter.

I think I actually got it to work!! Here's what I did:
Installed the MySql Connector
Added to and referenced MySql.Data & MySql.Data.Entity in my project
Added and EntityFramework 5.0 to my project
Added both MySql.Data & MySql.Data.Entity to the GAC.
Then I was able to use SqlEntityConnection and get the types!
There's gotta be an easier way to do this though. I particular, adding stuff to the GAC should not be a part of all this process. I mean, am I asking to much for this to work pretty much "out of the box"?!
Unfortunately, I'm extremely unfamiliar with .Net yet, so I couldn't get the whole thing working with the App.config file. Based on my searches here, it looks like I'm not the only one having troubles with this. If anyone has any feedback/suggestions please help!
I'm using MySQL database in my Ado.Net project. So I am using entity framework model first. It is good but when i want to add "mysql.data" (which i get from mysql web site named mysql data connector) to the Referances, it gives me an error like this: "object reference not set to an instance of an object". When i remove mysql.data from Referances, it works good. I think, it may cause mysq.data. I want to use mysql.data for searching queries. Because i don't know to code searching queries entity framework in my mysql ado.net project.
Could you help me, how do I solve the problem? I want to use both mysql.data and entity framework model first in my project.
Sincerely yours.
Now, I solved the problem. I provided "mysql.data.entity.dll" from MySQL web site, I added to referances and now everything is good.
I get this error no matter what version of SubSonic I use. When I query the database for data, it errors out, saying it can not connect to the database.
However, it is able to generate the .cs classes(ActiveRecord, Context, etc) when told to do so.
Any help is appreciated.
Thanks folks...
My guess is that you have your SubSonic generated classes in a separate project from where your main application is (in another project in the same solution). Your main application project references the project containg the SubSonic generated classes.
If this is the case, your main application project must also contain the connection string in a config file, similarly to what your other project has. You might also need to copy over some of the other SubSonic related items from your other project's config file as well.
I am ready and see all the tutorials and videos to configure the subsonic 3.0.0.3 with MySql and fail to genarate the ActiveRecords.cs. I use the MySQL.ttinclude in the folder to generate the class but it is still not working. I rename all the refenreces to SQLServer.ttinclude to MySQL.ttinclude and it still does not work. The error is: Metadata file "MySql.Data" could not by found.
I really need to use the subsonic version 3.0.0.3 with MySql 5.1.
I ran into the same issue. Make sure you actually run the installer for the MySQL connector as that put everything in the GAC. I tried to get it to work by just adding the ref to MySql.Data, and I got the same error as you. Everything worked perfectly once I ran their install.
Yes, all reference is setting. The two dlls Subsonic.core.dll and MySql.Data.dll. I think that's probable a bug int the 4templates for MySql. Many people still have problems whit the version for MySql. In the videos of rob for configurin and setting MySQL generate, it still work perfectly, but the files in the pack 3.0.0.3 are different.
dunno if you got same problem but i had trouble and it was because i had a C# project but was using the VB templates and it never created the files, also i have used mysql connector 6.1 if this helps as i think this is the most compatable version when it comes to stuff like this.
Yes, Iam using MySQL Connector 6.1 whit provider. Now I try to generate my class with the 4Templates to LINQ, but I don't have success. I see this error in VStudio 2008
Warning 1 Multiple template directives were found in the template. All but the first one will be ignored. Multiple parameters to the template directive should be specified within one template directive.
When I try to generate the class with the templates for Active Record, It's works, wonderfull, but I realy need the LINQ templates class generated.
