• Chris did not write the article, he wrote a blog entry pointing to my article. :-)
  

• jeez! I'm so sorry, scrwed a little bit there. *fixed*
  

• FYI, the BitVector32 has a bug in that the indexer always returns false for bit #31, even if it's set. The following code should reproduce it.
  
  
  
  
  
  class BitVectorBugDemo
  
  
  {
  
  
  static void Main()
  
  
  {
  
  
  BitVector32 bv = new BitVector32( unchecked((int)0xFFFFFFFF) );
  
  
  int mask = BitVector32.CreateMask();
  
  
  
  
  
  for ( int bit = 0; bit < 32; bit++ ) {
  
  
  Console.WriteLine( "Bit: {0}, Mask: {1:X}, value: {2}", bit, mask, bv[mask] );
  
  
  if ( bit < 31 ) mask = BitVector32.CreateMask( mask );
  
  
  }
  
  
  }
  
  
  }
  
  
  

• Is this a known bug? as in MS is aware of this?
  

• Yes, it was reported to them during the Everett beta.
  
  
  

• Just a note all: we are tracking this issue at Microsoft, and we do appreciate you taking the time to let us know about it. We didn't get a chance to fix this during Everett, but you can expect this to be fixed in the next release.
  
  
  
  
  
  Thanks,
