What is common language runtime (CLR)?

Answer: CLR is the.NET Framework’s fundamental and virtual machine component. It is the.NET Framework’s run-time environment that executes the code and aids in the development process by providing services like remoting, thread management, type-safety, memory management, robustness, and so on. It is in charge of controlling the execution of.NET programs, independent of the programming language used. It also aids in code management.

What is a web application framework, and what are its benefits?

Answer: It might be intimidating to learn how to create a contemporary web application. The majority of online apps contain a common set of features, such as:

This is something that a client computer will not be able to do, so these facts must be ‘posted back’ on the server.
