First off, if you're beginning a new project, use Entity Framework ("EF") instead of Linq to SQL since it now creates far better SQL (more like Linq to SQL does) and is simpler to manage ("L2S"). Since.NET 4.0 has been released, I believe Linq to SQL to be an old technology. MS has been quite transparent about not pursuing additional L2S developmen...
Although this discussion is old, I felt it was worth sharing. After using APM, you must Task-wrap the synchronous calls....Example:...//declare the delegate
private delegate MyResult MySPDelegate();
// declare the synchronous method
private MyResult MySP()
{
// do work...
}
...The synchronous procedure is then enclosed in a Task:...// wraps th...
The DDEX provider is installed for you by the SQL Server Compact Toolbox, which you must install on the new development machine. (You might need to open the Toolbox's About screen, click the DDEX install button, and then restart Visual Studio.)

When there is just one table, I have done the "fromsql" right off of the context; however, I recognise that this is not what you want, even if it advances the cause....var blogs = context.Blogs
