Explain how the assemblies and DLLs work in .NET
Assembly contains all the compiled types in your application along with their Intermediate Language (IL) code. It is also the basic unit of deployment in .NET. In the latest versions of .NET, i.e. .NET Core, an assembly is a file with a .dll extension, which stands for Dynamic Link Library.There are primarily four items in an assembly.Compiled TypesThe compiled IL code for all the types in your application.Assembly ManifestContains the metadata needed by the Common Language Runtime, such as the dependencies and versions that this DLL references.Its purpose is to describe the assembly to the runtime via the assembly's data, ...

Variables of value types directly contain the values. When you assign one value type variable to another, each variable associates with a different storage location in memory. Hence, Changing the value of one value type variable doesn't affect the value in the second variable.Similarly, when you pass an instance of a value type to a method, the compiler copies the memory associated with the argument to a new location associated with the parameter. Any changes to the parameter won't affect the original value. Since memory is copied for value types, they should be small (typically, less than 16 bytes).All the ...
Read MoreExplain how reflection works in .NET framework
A C# program compiles to a DLL assembly that contains the compiled C# code along with the metadata for the runtime, and other resources. C# provides a reflection API that lets us inspect the metadata and compiled code at runtime.Using reflection, it's possible to −Access the assembly metadata for all types inside the assemblyObtain a list of types and their members (methods, properties, etc.)Dynamically invoke the type members at runtime.Instantiate objects by only providing their nameBuild assembliesIn a traditional program, when you compile the source code to the machine code, the compiler removes all the metadata about the code. However, ...
