I just posted an update at the usual URL
http://EmpowermentZone.com/edsetup.exe
(Or use F11 to elevate)
The optional JAWS scripts for EdSharp have also been updated, so you may
wish to check that option at the end of installation if you are using JAWS.
Please let me know if you encounter problems with the following
enhancements.
EdSharp now uses the latest version of the .NET Framework available,
trying version 4, 3.5, 3.0, and then 2.0.
If you choose the C# or VB.NET compiler with Control+Shift+F5, then
compiling with Control+F5 uses the latest command-line compiler
available. So, you can use C# 4.0 syntax, for example, as in the fruit
basket example below.
A new command is called Format Code, Control+4. It arranges indentation
and other stylistic conventions of C-like languages, using the
Uncrustify utility from
http://uncrustify.sourceforge.net/
