Questions regarding assembly

[fh1996]

csc /target:module MyMod.cs

What's meaning of "NETMODULE" ?

Is /target:module always going to generate xxx.netmodule?

Does C# compiler only generate the following 3 types of files: .EXE, .DLL
and .NETMODULE?

When should produce .NETMODULE files instead of others?

Is the only use of .NETMODULE files to be added to an assembly?

What's the minimum composition of an assembly? At least a .DLL file or .EXE
file?

Thanks!

It's probably easiest thought of as "part of an assembly".

I believe so.

And .PDB, really.

Very rarely, IME - especially as you can't have multi-code-module
assemblies in VS.NET (2002/2003 at least).

Yes, IIRC - basically an assembly is a collection of modules, with the
appropriate "main" module (i.e. the one whose filename you specify)
containing a manifest saying which other modules are part of the
assembly. I can't remember what happens if the other modules also have
manifests - you could end up in strange situations, but basically you
wouldn't do that...

Thanks!

PDB files are not the "end" products but something of debugging info, aren't
they?

Thus, they can't be distributed as part of application or reused by other
projects for development.

What's "multi-code-module"? Code written in different languages?
"Very rarely"? Then whenis the appropriate time for doing this?

"main module"? What does this mean?

Indeed.

Well, you *might* want to distribute them as part of an app for a
specific customer, to get a more detailed stack trace.

Oh, and the C# compiler can also generate XML documentation.

Yup.

For one thing, if you really need to inclue code written in different
languages in a single assembly. Basically I wouldn't worry about it -
very few people are going to want to use it.

The one with the manifest / the one whose filename you specify. It's
only in that sense that it's the "main" one.

Re: Questions regarding assembly

Jon was right on the money but I wanted to clarify a few points:
A .netmodule is really just a .dll with a different file extension and no
assembly manifest.
The output file can have any extension you want to specify via the /out
option
An assembly consists of exactly 1 manifest and as many files as you want
(each file is listed in the manifest). It is illegal to try and create an
assembly with more than one manifest.
