Hello,

 I have just started to get a strange error when deploying my application on some pc's.  I am getting "Could not load file or assembly 'System.Core, Version 3.5.0.0, ....".  The error is occuring withing a very simple event handler:

private void pageThumbnails_SelectedIndexChanged(object sender, EventArgs e)
{
     if ( pageThumbnails.SelectedIndices.Count() > 0 )
          mi_PageSelected = pageThumbnails.SelectedIndices[0];
}

Does anyone have any idea why this error could be occuring.

 Thank You - Steve

 

It looks like you built with .NET 3.5, but they don't have it on their machine.  Can you build against .NET 2.0 instead?  If not, you need to have your installer check for 3.5 and install it.
