Using Informix .NET EF Core Provider

UseInformix(<Connection String>) is only override method specific to Informix, every .NET EF Core application calls method OnConfiguring(), in this method we need to call database provider specific connection API. Any database specific parameters needs to be passed as part of connection string.

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.UseInformix("Database=efcoredb; server=Informix; User ID=user1; Password=xxxx; connectdatabase=no");
}
