I keep getting this error in my asp.net webapi:

error 0175: The ADO.NET provider with invariant name 'MySql.Data.MySqlClient' is either not registered in the machine or application config file, or could not be loaded.

I do not have any refeences to mysql in my application.

What I have tried:

the connection string:

<add name="DefaultConnection" connectionString="Server=tcp:999.99.999.99;
        Initial Catalog=zbulkdb;Persist Security Info=False;User ID=xxxx;Password=xxxxxxxxxx;
        MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;
        Connection Timeout=30;TrustServerCertificate=True" providerName="System.Data.SqlClient" />

Providers:
<providers>
<provider invariantname="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer">

You most likely have a MySQL connection string defined in a higher level config file - either a parent application, or in the machine-wide config.

Try clearing the connection strings before adding your own:

XML

<connectionStrings>
    <clear />
    <add name="DefaultConnection" connectionString="..." providerName="System.Data.SqlClient" />
</connectionStrings>
