Using Linq to SQL and the autogeneration capabilities of DBML, foreign key relationships create EntityRefs in the DBML designer file. For example :
private int _USStateId;
private EntityRef<USState> _USState;
However, if I have the need for a table with numerous FK relationships to the same table, how can i control the autogenerated...
I'm having a database with a lot of foreign key relationships defined. When I simply drag any table involved in these FK connections into the DBML editor, so as to machine-generate the DBML file, these will all be represented as associations.
From here I'm able to make any changes to these associations: I might want the parent end of th...

I have two views: one is a normal view built from one table with an integer ID and other columns for the record (let's call it View1). I have another View (View2), which has an integer ID column and a second column named "table" (type: varchar).

I am using VS2010 with C#, and linq-to-sql.
Does anyone have any ideas of where to start looking for a solution?

Some time later I add a new property to one entity-type and now I want to upgrade the SQL-database to fit the new version of the dbml-schema. How do I accomplish this? Do I have to delete and re-create the database or upgrade it manually? Is ADO...
It instead creates it with a return value of int and doesn't create the spGetRowsFromTableRESULT object, which causes major problems in my application.
Previous solutions in the past have been to remove the stored procedure from the DBML file, re-compile (commenting-out any references) and re-adding it. Please if anyone has any informa...

I've got a DBML file in my project with all my LinqToSql objects. Initially I imported them from the DB, and all was well. Now as my DB has been growing, I've been adding the new tables to the diagram in the O/R Designer, but they always get appended to the end of the XML. This is a bit of a pain, because when I'm defining foreign key...
