Microsoft's .NET Framework
To use VLF.NET both developers and end-users need to have Microsoft’s .NET Framework 2.0 (or later) and .NET Framework 2.0 Service Pack 1 installed.
If .NET Framework 3.5 has been installed, .NET Framework 2.0 Service Pack 1 does not need to be installed separately.
Some problems have been reported when installing .NET Framework 2.0 Service Pack 1 on Vista, in which case .NET Framework 3.5 will be have to be installed.
.NET 2.0 Software Development Kit (SDK) is not required.
