So I found a tutorial on how to generate a class for my database.

So I found a tutorial on how to generate a class for my database. I installed Mono for windows, I got DbLinq and Npgsql, but i’m having a slight problem understanding how to generate the class.

The tutorial says I should use this in mono

mono DbMetal.exe /conn:"server=localhost;user id=user;\
password=password; database=db" /provider=PostgreSQL \
/code:db.cs /pluralize

If I write that into Mono i get this message 

Reading schema from DBML file '\'
DbMetal : Access to the Path '\' is denied

What path should be there? The tutorial doesn’t specify.

Here is the tutorial : http://romain.blogreen.org/blog/2009/07/linq-postgresql-and-mono/

What should I do to fix this?

Thanks in advance!

    On Windows/.NET, you are supposed to use SqlMetal,

    According to DbMetal’s page, it is an equivalent of SqlMetal,

    The article you followed was written from Mono/Linux, so it may not demonstrate what are the parameters you should use on Windows.
