• Visual Studio 2008 (Pre-release) What the method EntitySet.RemoveAt is for?

  When I remove an entity with this method, the entity is removed from the collection.

• Visual Basic Programming - the best (modern?) approach....

  I hope this can be steered towards the most suitable forum... I'm a hardware designer and started writing in 'BASIC' in the 1970's, which was light relief from FORTRAN.

The language was rigidly defined and documented, and apart from a few odds and ends, that book was all you needed to write your program ...Show All
