.Net Runtime Library for Delphi

The .Net Runtime Library for Delphi (CNClrLibrary) is the best library to work with .Net framework and .Net libraries from Delphi. It is designed to provide a way to interact with applications written in anyone of the .Net languages (such as C#, Visual Basic.Net, Delphi.Net, JScript.Net, etc) from Delphi. 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
