How do I setup ASP.NET MVC 2 with MySQL? - mysql

Is it possible to setup ASP.NET MVC 2 to work with a MySQL database?

I'm assuming that you have Visual Studio Professional 2008, have access to an instance of MySQL server, and have moderate to advanced development experience. This MAY work with VS2008 Web edition, but not at all sure.
If you haven't, install MySQL Connector for .NET (6.2.2.0 at the time of this write-up)
Optional: install MySQL GUI Tools
If you haven't, install MVC 2 RTM, or better yet, use Microsoft's Web Platform Installer. (UPDATE: MVC 2 has now been released for quite some time)
Create an empty MySQL database. If you don't want to access your application with the MySQL root user account (insecure), create a user account and assign the appropriate privileges (outside the scope of this write-up).
Create a new MVC 2 application in Visual Studio
In the MVC 2 app, reference MySql.Web.dll. It will either be in your GAC, or in the folder that the MySQL Connector installer put it.
Modify the connection strings portion of your web.config:
<connectionStrings>
<remove name="LocalMySqlServer"/>
<add name="MySqlMembershipConnection"
connectionString="Data Source=[MySql server host name];
userid=[user];
password=[password];
database=[database name];"
providerName="MySql.Data.MySqlClient"/>
</connectionStrings>
8.
Modify the membership portion of your web.config:
<membership defaultProvider="MySqlMembershipProvider">
<providers>
<clear/>
<add name="MySqlMembershipProvider"
type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web,
Version=6.2.2.0, Culture=neutral,
PublicKeyToken=c5687fc88969c44d"
connectionStringName="MySqlMembershipConnection"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="true"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
applicationName="/"
autogenerateschema="true"/>
</providers>
</membership>
9.
Modify the role manager portion of your web.config:
<roleManager enabled="true" defaultProvider="MySqlRoleProvider">
<providers>
<clear />
<add connectionStringName="MySqlMembershipConnection"
applicationName="/"
name="MySqlRoleProvider"
type="MySql.Web.Security.MySQLRoleProvider, MySql.Web,
Version=6.2.2.0, Culture=neutral,
PublicKeyToken=c5687fc88969c44d"
autogenerateschema="true"/>
</providers>
</roleManager>
10.
Modify the profile portion of your web.config:
<profile>
<providers>
<clear/>
<add type="MySql.Web.Security.MySQLProfileProvider, MySql.Web,
Version=6.2.2.0, Culture=neutral,
PublicKeyToken=c5687fc88969c44d"
name="MySqlProfileProvider"
applicationName="/"
connectionStringName="MySqlMembershipConnection"
autogenerateschema="true"/>
</providers>
</profile>
At this point, you ought to be able to run the app and have the default ASP.NET MVC 2 home page come up in your browser. However, it may be a better idea to first run the ASP.NET Web configuration Tool (in Visual Studio top menus: Project -> ASP.NET Configuration). Once the tool launches, check out each of the tabs; no errors = all good.
The configuration tool at Nathan Bridgewater's blog was essential to getting this working. Kudos, Nathan. Look for the "Configuration Tool" heading half way down the page.
The public key token on the MySql.web.dll that I've posted here ought not change any time soon. But in case you suspect a bad token string from copying and pasting or whatever, just use the Visual Studio command line to run: "sn -T [Path\to\your.dll]" in order to get the correct public key token.
There you have it, ASP.NET MVC 2 running over MySQL. Cheers!

I belive at "10. Modify the profile portion of your web.config::"
<profile>
<providers>
<clear /> ...
<add type="MySql.Web.Security.MySQLProfileProvider,......
type= has to be:
type="MySql.Web.Profile.MySQLProfileProvider"
because in "MySql.Web.Security" I have not found any method MySQLProfileProvider.
(but using Version 6.4.4. for .NET 4.0)
And at least, you have to create your own classes for creating the database tables, if there is no ready configured database.

"Could not load file or assembly 'MySql.Web" But I am not using MySQL?

I have an ASP.Net MVC 5 web site that is using Entity Framework and SQL for the database. When I publish the site to my host and run it I now get an error about MySql.Web.
Could not load file or assembly 'MySql.Web, Version=6.8.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. The system cannot find the file specified.
The error message also focus on this line from the machine.config
<add name="MySQLMembershipProvider"
type="MySql.Web.Security.MySQLMembershipProvider,
MySql.Web, Version=6.8.3.0, Culture=neutral,
PublicKeyToken=c5687fc88969c44d"

requiresUniqueEmail="false" passwordFormat="Clear"
maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7"
minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10"
passwordStrengthRegularExpression="" />
I do not use MySql in my project and can not find any references to it in any of my configuration files.
I have read some other posts on SO that talk about adding the MySql connector to my configuration but don't understand why I would need to do that if I don't use MySql anywhere??
It looks like someone installed the MySQL Connector on your machine.
You should be able to remove providers from your app using a <clear/> or <remove name="MySQLMembershipProvider" /> in your web.config.

Using membership provider in MVC2 with MySQL

I've read several posts in this forum about this but nothing seems to work. I'm trying to replace the default SQL Server based providers with MySQL providers using the latest version of connector (6.3.6.0) and VS2010, but I keep getting an error when accessing the Security section in WSAT. Here are my steps:
1) create a new mysql database.
2) create a new MVC2 application.
3) change web.config as follows:
<connectionStrings>
<remove name="LocalMySqlServer"/>
<add name="LocalMySqlServer"
connectionString="Data Source=127.0.0.1;Port=3306;Database=Sample;User id=root;Password=mysql;"
providerName="MySql.Data.MySqlClient"/>
<remove name="ApplicationServices"/>
<add name="ApplicationServices"
connectionString="Data Source=127.0.0.1;Port=3306;Database=Sample;User id=root;Password=mysql;"
providerName="MySql.Data.MySqlClient" />
</connectionStrings>
...
<membership defaultProvider="MySqlMembershipProvider">
<providers>
<clear/>
<add name="MySqlMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider,MySql.Web,Version=6.3.6.0,Culture=neutral,PublicKeyToken=c5687fc88969c44d"
connectionStringName="MySqlMembershipConnection"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="false"
requiresUniqueEmail="true"
passwordFormat="Hashed"
maxInvalidPasswordAttempts="5"
minRequiredPasswordLength="6"
minRequiredNonalphanumericCharacters="0"
passwordAttemptWindow="10"
applicationName="/"
autogenerateschema="true"/>
</providers>
</membership>
<profile>
<providers>
<clear/>
<add type="MySql.Web.Profile.MySQLProfileProvider, MySql.Web, Version=6.3.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"
name="MySqlProfileProvider"
applicationName="/"
connectionStringName="MySqlMembershipConnection"
autogenerateschema="true"/>
</providers>
</profile>
<roleManager enabled="true" defaultProvider="MySqlRoleProvider">
<providers>
<clear />
<add connectionStringName="MySqlMembershipConnection"
applicationName="/"
name="MySqlRoleProvider"
type="MySql.Web.Security.MySQLRoleProvider,MySql.Web,Version=6.3.6.0,Culture=neutral,PublicKeyToken=c5687fc88969c44d"
autogenerateschema="true"/>
</providers>
</roleManager>
<machineKey validationKey="AutoGenerate" validation="SHA1"/>
When I run WSAT and click Security, I get this error:
There is a problem with your selected data store. This can be
caused by an invalid server name or
credentials, or by insufficient
permission. It can also be caused by
the role manager feature not being
enabled. Click the button below to be
redirected to a page where you can
choose a new data store.
The following message may help in
diagnosing the problem: The source was
not found, but some or all event logs
could not be searched. To create the
source, you need permission to read
all event logs to make sure that the
new source name is unique.
Inaccessible logs: Security.
Could anyone tell me what's wrong with this procedure? Thanks to all!
finally I got it working and I'd like to share the information here. I am using the latest version of Connector/Net (6.3.6) in an ASP.NET MVC 2 website. Here is what I did:
1) create a new MySql database (or just use yours if any).
2) ensure that your machine.config has enabled schema autogeneration for MySQLMembershpProvider. As you probably know, machine.config is typically placed under c:\windows\microsoft.net\framework[version]\config\machine.config. Find under the entry for MySQLMembershipProvider and append the attribute autogenerateschema="true" to the element . The whole element will look like this:
<add name="MySQLMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.3.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" connectionStringName="LocalMySqlServer" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="true" applicationName="/" requiresUniqueEmail="false" passwordFormat="Clear" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="1" passwordAttemptWindow="10" passwordStrengthRegularExpression="" autogenerateschema="true"/>
3) in your web.config (I'm referring to a newly created web application, so make your changes if required) change the connection strings and providers so that they refer to MySql. Typically: under connectionStrings add:
<remove name="ApplicationServices"/>
<add name="ApplicationServices" connectionString=connectionString="server=YOURSERVER;UserId=YOURUSER;password=YOURPASSWORD;Persist Security Info=True;database=YOURDATABASE;charset=utf8" providerName="MySql.Data.MySqlClient"/>
(BTW, notice the charset=utf8 in the connection string: this is not required for membership, but it is required if you are going to use this connection string to exchange Unicode data: it is not enough to just define the character set in your MySql table fields!).
Also, under membership / providers... ensure that the membership provider element (typically something like add name="AspNetSqlMembershipProvider"...) connectionStringName attribute refers to the connection string you set above (in my case, connectionStringName="ApplicationServices"). Do the same for profile and roleManager providers, which should look like this:
<profile>
<providers>
<clear/>
<add type="MySql.Web.Profile.MySQLProfileProvider, MySql.Web, Version=6.3.6.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"
name="AspNetSqlProfileProvider"
applicationName="/"
connectionStringName="ApplicationServices"
autogenerateschema="true"/>
</providers>
</profile>
<roleManager enabled="true" defaultProvider="MySqlRoleProvider">
<providers>
<clear />
<add connectionStringName="ApplicationServices"
applicationName="/"
name="MySqlRoleProvider"
type="MySql.Web.Security.MySQLRoleProvider,MySql.Web,Version=6.3.6.0,Culture=neutral,PublicKeyToken=c5687fc88969c44d"
autogenerateschema="true"/>
</providers>
</roleManager>
<machineKey validationKey="AutoGenerate" validation="SHA1"/>
(Note the SHA1 validation!).
4) launch WSAT from Visual Studio and let it configure your MySql database. It should create all the tables required and let you create users and assign roles. Beware of table names casing! With WSAT tables like myaspnet_Users (not myaspnet_users) are created, and this might lead to confusions (MySQL Workbench seems to be confused by this and will show you just 1 table if you have 2 tables with their names differing only by casing. Tools like Navicat seem smarter in this respect). It's best to let WSAT create its tables to avoid this fuss.
Finally, remember that if you are going to use my_aspnet... tables in some relationships, you must make sure you select the proper MySQL database engine, i.e. not MyISAM but InnoDB, otherwise your foreign keys even if set will be ignored.
That's all I can share for this issue. Hope this might save some hours to someone else...
Perhaps I found the culprit: the PC I was working today had not its machine.config (for .net 4) configuration set for autogenerateschema="true" (btw there is a typo in my code above, the connection string name is not correct, but this happened only by copy/paste in my post). So maybe this is useful for all the newcomers like me: remember to set autogenerateschema="true" in
Thanks anyway

MVC2 MySQL Hosting Issue?

I have an MVC2 app that utilizes MySql.Web ver. 6.2.2.0, on my dev machine locally it works fine!
However, once I upload it to my http://www.winhost.com account I get the following error:

Add references to the assemblies, add autogenerateschema="true" attribute to both as:

use ASP.Net configuration tool.
I had this problem, it turned out there was no password in my connection string, I think checking carefully that your connection string is correct would be a good place to start.
My problem was I had "localhost" in my connection string instead of the IP address of the webhost's MySQL server.
Once I changed that in my web.config file it worked fine, so you need to check your web.config file very carefully.
I was experiencing this exact same issue. Mine ended up being a case issue since I was deploying my site to a linux server running Mono. Enabling autogenerateschema="true" helped me figure this one out. Some hosts won't let the code generate the necessary tables though, so if it doesn't auto-generate your schema then check out casing issues.
CodeMonkey's solution worked for me... I was actually deploying a new app to a Win 2008 Server VM. The schema could not be generated until I specified the LocalMySql connection string and set the MySQLRoleProvider autogenerate to true.

ASP.NET Membership/Role providers for MySQL?

I am not at all familiar with ASP.NET membership/roles. This is my first time using it, and my first time trying ASP.NET MVC. When I create my first project for MVC, it gives me a lovely template to create an account. I was excited to see that I did not have to do this manually. However, it failed because it cannot connect to SQL Server. I do not have SQL Server, I have MySQL. Is there any easy way I can get this system to use MySQL instead, or will I have to create my own authentication?
Got it figured out! Using version 6.2.2.0 of MySql Connector/Net, follow these steps...

In my scenario, I do not need to connect to MySQL from my .NET web applications. Therefore, I solved this problem by doing two things:
1) Uninstall MySQL .NET Connector (all versions)
2) Inside the Web.Config file, remove all keys that were added after the MySQL installation. (Or else, copy back the original Web.Config file before installation to the .NET web application root folder)
Now, my .NET application is bac

Note: In my case, the machine.config to be edited was the 32 bit one (they didn't specify which, and editing the 64bit one didn't help).
Click on the menu Project followed by ASP.NET Configuration.
That will create the sql database for you in the Data folder.
Use Visual Studio to look at the data.
Hope this helps.
Edit
I should add that you can then use Ctrl+Alt+S to see the Server Explorer which should then allow you to see your database with its tables and the data.
You shouldn't need SQL installed.
