  Hi,

  I am using VS2008 and .net 3.5, #. i m trying to access default.aspx in the browser and it shows the error as

  "Could not load file or assembly 'System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified."

   

  Also when i use any of the Ajaxcontrol toolkit tools, i m getting the these kind of errors. I hav copied the ajaxcontroltoolkit.dll and .pdb in the bin folder. but i m getting the same error. Please help me.

   I will  be grateful if anyone can send me the correct web.config file which solves these kind of error in .net 3.5 extensions

  Thank You

  Maran
