Licensing Scheme 

• Typemock Isolator now has licenses for Commercial, Personal and Open Source usage. Open Source installers can be downloaded independently from the others. More information can be obtained here.

• A new assembly, Typemock.ArrangeActAssert.DLL contains the new API for the triple-A syntax. This is only available for use with Net framework 3.5. Read more on the new API here. The list of new API contain:
• Object creation:
  • Default: All void calls are stubbed, and you must specify return values
  • All methods are called in their original implementation
  • All void calls are stubbed, all others return nulls (or 0 for value types)
  • All void calls are stubbed, all others return fakes, which their methods return fakes, and so on recursively.
• Swapping a fake�s behavior with a future created instance. This is similar to the MockManager.Mock()
• Setting behavior on method calls (WhenCalled API)
  • Return a fake value
  • Call original method
  • Ignore a void call
  • Throw an exception
• Verification that calls
  • were called with exact arguments
  • were called with any arguments
  • were not called
• Chains are also supported both in WhenCalled and Verify

Other New Features 

• Added support for linking with Typemock Racer

In 5.0.0:

• When VS2008 is not installed to 'regular' path and running with MSTest Isolator can't mock certain classes.
• A crash in VS2008 that was caused by 4.3.1 was fixed 

• Isolator now installs into Program Files->Typemock->Isolator 5.0. When removing former versions, some artifcats on the file system and menus may remain, which can be deleted manually. 
• On 64 bit machines the Isolator license may dissapear. If this happens, re-enter your license and company name through the Isolator Configuration window.
