Hi,

I am totaly novice in .NET and I am studying a book about this. There
was mentioned "assembly". I did not understand, how function does it has .
I would like to know the exact run of code (intermediate language and so
on). Is there any page on internet, which makes me clear?

Thanx
 
assembly language I presume? Assembly language is not
something you learn. . . it is the code that the computer
runs in and it consists of 0's and 1's (Looks something
like 00100011100010101100101110001) 1's are on, and zero's
are off. It consists of 8 bits (binary units) that make up
a byte.

You don't really learn it, and you don't really need to.
All you need to know is that it is the language computers
talk in. With .Net, whatever language you program in, gets
converted to this assembly language so it can speak to any
type of computer. (Cross platform.)

Anyone else, please correct me if I am wrong.
 
Assembly can mean 2 different thing.

The assembly language is what was refered to in the first response. However, the code below is actually machine code (the 0 and 1s). Machine code is
ultimately what will get run on the machine, regardless of what you actually program in. Assembly language is a slightly more anvanced language, but still very
very low level. You need to specify which register to put your numbers, then you can do ver y simple arithmatic like add. Assembly language (I believe) is
specific to the machine (or at least the chip); for instance I learned a little 8086 assembly in college. MSIL (microsoft intermediate language) is what your code is
compiled into when you build. It is low level like assembly. You can take a look at it using ildasm.exe. At runtime, the MSIL is converted into the machine code
that runs on the machine. Because this happens at run time, it can optimize some things that cannot be done if we were to compile in into machine code at the
beginning.

However, I an assembly has a different meaning in visual studio.net. An assembly is a unit of code; it is usually a dll or exe. I would just think of it as your dll or
exe, although it is possible(but not through the VS IDE, only through the command line tools) to have an assembly that is in multiple dlls. An assembly in the unit
that permission can be set on, and what you can access without adding a reference.

Hope this helps;
