The following problems in the Microsoft .NET Framework 1.1 are fixed in this hotfix rollup package:
  • When you compile some code, it may have valid Microsoft intermediate language (MSIL). However, when you run the compiled application, you receive the following unhandled exception error message:
    System.NullReferenceException: Object reference not set to an instance of an object.
    If optimization is turned off, you do not receive this exception error message.
  • Unmanaged Microsoft Component Object Model (COM) clients that enumerate through the current connections of a connection point or event that is exposed by a .NET Framework component do not exit the enumeration loop. The enumeration is completed through the IEnumConnections::Next method, and then the client application appears to stop responding. This problem may occur in a Microsoft Visual Basic 6.0 client when you use the WithEvents keyword.
  • If you call a Web service method, and if the method call takes a long time to return (typically, more than 100 seconds), the client application may receive the following exception error message:
    The underlying connection was closed
