SYMPTOMS

In Microsoft Visual Studio .NET, when you try to build a Microsoft .NET Framework Software Development Kit (SDK) ObjectPooling sample program, you may receive the following build error:
'Public Overridable Overloads Sub Dispose()' is declared in project 'System.EnterpriseServices.dll', which is not referenced by project 'OPDemo.exe'.

    Any other version of Microsoft Visual Studio .NET

    C:\Program Files\Microsoft Visual Studio .NET\FrameworkSDK\Samples\Technologies\ComponentServices\ObjectPooling\VB

  2. In Solution Explorer, open the OPFormVB project.
  3. Right-click References, and then click Add Reference.

    The Add Reference dialog box appears.
  4. Click the .NET tab, and then click System.EnterpriseServices.
