LINQ - Sequence contains no elements

  • Article

Today I got an exception saying "Sequence contains no elements " when using LINQ against Windows Azure tables. I did a quick search and found that it is due to that I used First<> instead of FirstOrDefault<> in my code. The below link explains the issue.

btw, I expected that First<> returns null instead of throwing exception.

    Good point. Thanks Keith. I expected it returned null instead of throwing exception.
