Chilkat .NET Core Classes for .NET Standard 2.0 and later

The .NET Core assembly is cross-platform and runs on Windows, Linux, and macOS. This makes it suitable for desktop and ASP.NET Core applications, cross-platform console applications, and cloud services. (Most applications should reference the "ChilkatDnCore" package, for .NET 6.0 and later.)

About the Chilkat Library

The Chilkat .NET library is a comprehensive suite of software components that provide a wide range of functionality for use in .NET applications.
