For .NET 2.0, consider using Microsoft.Win32.SafeHandles.SafeFileHandle instead. It can be used where IntPtr is used. If you use a SafeFileHandle, do not call CloseHandle as the CLR will close it for you (even if it's already closed).

NOTE: This class needs some changes. The CloseHandle call will destroy the event when the last handle is closed. This makes it hard for one application to "lock" the event while making another wait on it since this class is always closing the handle. An alternative that I found to work is to have the CreateEvent call in the constructor and implement IDisposable by moving the CloseHandle call to the Dispose method.

The sample application below demonstrates how to use MsiRecordSetString, MsiOpenDatabase, MsiCreateRecord, MsiCloseHandle, MsiDatabaseOpenView, MsiViewExecute, MsiDatabaseCommit, and MsiViewClose in C# to modify a property value in an MSI database. To run it, simply create a new Windows Console application and replace the code that Visual Studio gives you with the code below. You may have to modify the namespace name. The sample as-is requires a valid MSI database named SETUP.msi, with a property named PROPERTY1 in the Property table, to be located in C:\. You can of course change the path to your MSI database in the calls to ChangeMSIProperty() in Main() and use any existing property you wish.
