• .NET Development OutOfMemoryException and Garbage Collection doesn't work how I thought it would

  I designed this code snippet to test garbage collection.  It doesn't do what I thought it would do though.  The idea was to allocate a chunk of memory, but to discard the reference to that chunk by letting the variable that holds the reference fall out of scope.  When it runs out of memory on the heap, I expected the garbage collector to run automatically and that the allocation would succeed.  But there are a couple of w ...Show All

• SQL Server SQL CE Push ConnectTimeout

  My application synchronises data with a SQL Server using RDA, the synchronisation process take place in a background worker thread.
