.NET dotnet framework programming interview questions
1) Has own
class libraries. System is the main namespace and all other
namespaces are subsets of this.
It has CLR(Common language runtime, Common type system,
common language specification)
All the types are part of CTS and Object is the base class
for all the types.
If a language said to be .net complaint, it should be
compatible with CTS and CLS.
All the code compiled into an intermediate language by the
.Net language compiler, which is nothing but an assembly.
During runtime, JIT of CLR picks the IL code and converts
into PE machine code and from there it processes the
request.
