Linq2SQl eager load with multiple DataLoadOptions

Question

I like to fetch the data with eager-loading using Linq2SQL. The code is similar as :

       DataLoadOptions options = new DataLoadOptions();

       options.         


        

Answer 1

I hit this issue in some code too, and after much experimenting and googling it looks like LINQ can only join across a single one-to-many relationship from each table : if you try to specify more than one to pre-load it just (randomly?) picks which one to pre-load and which others to leave deferred (simply ignoring those LoadWith hints)

Other people have posted this too, for example
