FIX: System.ArgumentOutOfRangeException exception when you run a .NET Framework 4-based application that uses the MemoryCache.CreateCacheEntryChangeMonitor method


Consider the following scenario:
  • You run a Microsoft .NET Framework 4-based application that uses the MemoryCache class on a computer.
  • The time of the computer has a positive Coordinated Universal Time (UTC) offset.
  • The application calls the MemoryCache.CreateCacheEntryChangeMonitor method.
In this scenario, the application encounters a System.ArgumentOutOfRangeException exception and then crashes. Additionally, you receive the following error message:
The UTC time represented when the offset is applied must be between year 0 and 10,000.


This issue occurs because the implicit conversion between a DateTime object and a DateTimeOffset object has an error.

When the MemoryCache.CreateCacheEntryChangeMonitor method uses the DateTimeOffset object internally, an invalid operation is performed.
