When you compile an application, the CIL code is stored in an assembly Assemblies include both executable application files and libraries Assemblies also include meta information and optional resources All of the above Which of the following statement related to CIL and JIT are correct? The just-in-time part of the name reflects the fact that CIL code is compiled only when it is needed Your code gets compiled into Just In Time (JIT) code Several JIT compilers exist, each targeting a different architecture, and the CLR/ CoreCLR uses the appropriate one to c All of the above Which of the following statement related to Managed Code are correct? The role of the CLR/CoreCLR doesn’t end after you have compiled your code to CIL and a JIT compiler has compiled th Code written using the NET Framework and NET Core are managed when it is executed CLR/ CoreCLR looks after your applications by managing memory, handling security, allowing cross language debuggin All of the above Which of the following statement related to Garbage Collection are correct? This method makes sure that the memory used by an application is freed up completely the application is no longer in NET garbage collection works by periodically inspecting the memory of your computer and removing anything from it Using Garbage collection, you can separate logically related code into an individual file so that it can be worked on ind All of the above Linking makes it easy to locate specific pieces of code when you need them and enables teams of developers to divide th otherwise satisfactory sections or sections other people are working on True Fals e Which of the following application can be developed using C#?
