CNClrLibrary allows Delphi to use .Net libraries without the need for registry entries, COM registrations, or changes to the .NET libraries. Competitive Advantages: - No extra dll is required when deployed. - No COM registration of .Net Libraries is required when deployed. - There are tools to generate your .Net Libraries into Delphi pas files. - Allows Delphi to consume .Net libraries as if they were native code. - Full access to .Net Framework Class Library. - Easy to use. CNClrLibrary can do so much: - Access .Net Framework Class Library. - Access Third Party .Net Libraries. - Access Your .Net Libraries. - etc Latest Version: 6.0.7.0
