What's wrong with Linq to SQL?

Question

What\'s wrong with Linq to SQL?

Or - what about Linq to SQL would make it unsuitable for a project, either new or existing? I want to hear about why you would

Answer 1

For a project that needs to make use of databases other than SQL Server:

1) You are locked in to using SQL Server

For a project with complex entity relations and/or relations that change gradually over time:

2) You are locked in to 1-to-1 mapping of tables to classes

For a project that must use 1.x versions of .NET

3) Won't work with .NET 1.x
