Question

Im trying switch the Visual Studio asp.net mvc web app template to use MySql for user auth. So far iv installed mysql and .net connectors, created a custom membership provider (although it just throws notsupported atm) and edited the web.config to use them. But no matter what I try i just keep getting the following…

“Failed to generate a user instance of
SQL Server due to failure in
retrieving the user’s local
application data path. Please make
sure the user has a local user profile
on the computer. The connection will
be closed.”

I’ve even searched the entire solution for any reference to sql to make sure its not set somewhere I was’nt expecting it too.

accompanying config is as follows…

<connectionStrings>
    <add name="MySqlMembershipConnection"
    connectionString="Data Source=server_name;
                      user id=username;
                      password=password;
                      database=database_name;"
    providerName="MySql.Data.MySqlClient"/>
</connectionStrings>

<membership>
      <providers>
        <add name="MySqlMembershipProvider" type="testmvcappp.MySqlMembershipProvider" />
      </providers>
<membership>

Thanks, Tom.

NOt sure, but a couple thoughts.

1) It’s a generally good practice to call <clear/> in your providers list first to make sure that nothing was set in a “higher” web.config.

2) Is your custom membership provider inheriting from ProviderBase or from the SqlMembershipProvider? If the latter, it may be calling the inherited setup methods
