While I am trying to generate the database using Nuget command:-

Following things are already cross checked & tried by me:-

</connectionStrings>

<providers>
  <provider invariantName="MySql.Data.MySqlClient" type="MySql.Data.MySqlClient.MySqlProviderServices, MySql.Data.Entity.EF6, Version=6.8.8.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d"></provider>

In Entity Framework The type initializer error is most likely due to malformed Web.config files, like having two or more sections of connection string, or having problem in the connection string itself, such as invalid provider.
