  We have written a dll in C# in 2002.  We are calling this dll from numerous projects all written in Visual Basic.  Here is where the problem comes in.  The projects written in 2005, the dll is called and is ran in less then 2 seconds I know this because the dll opens a form for our users to log in with.  Unlike the 2005 version a project written in 2003 takes up to 13 seconds to load the same dll.  We have tried this on 3 different machines with several different projects all coming up with the same results.

  Can anyone tell me why this is happening and how to make the projects written in 2002 load the dll as fast as the 2005 projects.

   Thanks in advance,

  Chris.

  This is only a guess because no code, but there might be a few reasons why this is happening:

  1. Some areas of your code are not managed, such as using the Object type, and so boxing is occurring.

  2. There is some performance loss through interoperability between C# and VB.

  3. You are trying to call a COM component through VS2005 which works on a different framework (although this is a VB6 fix, it might work), use the Aximp utility to manually create an interop assembly, and you can then reference the dll in you project.
