• Which is more flexible in regards to database changes, EF 4 or Linq to SQL

  - by JBeckton

  Reading about both Linq to SQL and Entity Framework I have developed the impression that EF is more suitable for apps that get data from multiple data sources. But as I am reading about MVC2 models I see an example where EF is more loosely coupled with your data model. If I have to add or remove some columns from a table then what is involved in updating my model or DAL with each of these implementations?

• LINQ to Entities, SQL Server version and setting ProviderManifestToken at runtime

  - by chris

  We have developers some developers who are developing against a SQL Server 2005 database, while others are using 2008. We just discovered that generating the edmx against a 2008 database set the ProviderManifestToken to 2008, which means some queries won't work against a 2005 database. While this is a known issue, is there any way to set this value at run time, based on a config file?

• Table Naming Dilemma: Singular vs. Plural Names

  - by ProfK

  Convention has it that table names should be the singular of the entity that they store attributes of. I dislike any T-SQL that requires square brackets around names, but I have renamed a Users table to the singular, forever sentencing those using the table to sometimes have to use brackets. My gut feel is that it is more correct to stay with the singular, but my gut feel is also that brackets indicate undesirables like column names with spaces in them etc. Should I stay, or should I go?
