Which is the heart of the .net engine?

  
The CLR is the engine that drives every .Net application. It consists of the jitter [the Just In Time compiler] that compiles CIL [Common Intermediate Language] to native object code, the garbage collector, the Common Type System [CTS] and the exception handling machinery. The CLR gets threads and bulk memory management from the underlying operating system, and not much else. (More...)

Why NoLock is used in Sql Select Query?

  
Advantage:
applying nolock in select statement will increase
concurreny and performance in fetching.

Disadvantage:
it does'nt consider the transaction scenario, even if the
transaction is under process not yet commited or rollback
it will fetch the current record
eg

begin tran
insert into tablename
values('1','asdf')

select * from tablename with (nolock)

-- it will display the table with inserted record.
but the transaction is not completed, it can be rollback
so it became dirty read.
