The C# compiler always compile to MSIL byte code.

Or one can read the C# specification.

Let me make a few quotes:

...
When C# programs are compiled, they are physically packaged into 
assemblies. Assemblies typically have the file extension .exe or .dll, 
depending on whether they implement applications or libraries.
...
Assemblies contain executable code in the form of Intermediate Language 
(IL) instructions, and symbolic information in the form of metadata. 
Before it is executed, the IL code in an assembly is automatically 
converted to processor-specific code by the Just-In-Time (JIT) compiler 
of .NET Common Language Runtime.
...

You like to talk about your many years of programming experience - did
those include such exotic activities as reading specifications
to understand how things are supposed to work?

Yes.  It's too bad you don't understand the specifications.

But then you've shown this propensity multiple times, arguing with many
people more knowledgeable than you.  And each time you only end up
making a bigger fool of yourself.

C# can also be compiled into executable code.  And the .NET framework
can be called from other languages.

It's a language. And it has nothing whatsoever to do with Java, so
this post is off topic in this group.

It's used primarily (but not exclusively) in browsers. All kinds of
things are done with it, from checking form input to enabling video
playback (with HTML5).

As I said earlier, it has no relation to Java, except a similar name.

>What are the limitations of the language, in terms of 
>hardware, memory access, security, etc.?

It depends on the environment where it runs.
