The phrase refers to the package necessary to execute applications built with the latest version of a popular open-source, cross-platform framework on a Windows server. It includes the runtime components needed to host these applications within Internet Information Services (IIS) or through other supported hosting mechanisms. Without this package, a server cannot properly interpret and run the compiled code of these applications, leading to errors or complete failure of the application to function.
The availability of the proper runtime environment is crucial for the successful deployment of applications developed with the framework. Historically, managing dependencies and ensuring the correct versions were installed on hosting servers was a significant administrative overhead. This package simplifies the process by bundling all the required components, reducing the risk of version conflicts and compatibility issues. By providing a single, comprehensive installer, it lowers the barrier to entry for developers and system administrators deploying applications.
