In the Assembly Information, you can set the assembly version and the
file version. What is the difference between the two? The
documentation is not exactly helpful in this area.
I had the assembly version set to a unique number, and just left the
file version as 0.0.0.0. My program crashed on another computer, and
the windows error report stated: "AppVer: 0.0.0.0", so I am thinking
maybe the file version is more important (unless this was an older
version of my program that had BOTH assembly and file version set to
0.0.0.0).
When you right-click properties of a file, it shows the File version
at the top, and both assembly and file versions inthe list box at the
bottom, with assembly listed first.
It is totally unclear to me what either is for, which is more
important. For now, I'll just set them to both be the same.

Without trying to sound daft, the assembly version controls the
version of the assembly, and the file version controls the version of
the file. If may be useful to keep them in sync, but note that
"fusion" uses the assembly version as part of the identity when asking
"is this the right dll". The file version is not really used so much
by .Net, but may be used by OS tools. Changing the assembly version of
a strongly named assembly generally requires you to tell the callers
to forward to the new version (via policy), else recompile.
Right or wrong, I have tweaked my build process to timestamp the build
into the file version, but it leaves the assembly version for manual
planned change. That way I can always track the history of a dll,
without quite as much pain for releasing a hotfix as changing the
assembly version.

Nothing very sophisticated I'm afraid. I considered some funky MSBuild
add-ins, but chickened out. Basically I have a build script (actually
a C# exe) that traverses a source tree looking for things to build
(updating references / dependencies, setting config for the
environment [WCF endpoints, etc], figuring out the build order etc); I
simply added a few lines into that which use a regex to find and
update the necessary attribute in the source code. Similar to the
standard VS auto-versioning, but with an offset that won't run out of
numbers for a few extra decades.
Sorry it wasn't something more exciting ;-p

Ok, so basically the assembly is one whole compilation, and that has a
number. But, the file version refers to the final .exe made, so it is
also the entire assembly. I still fail to see the difference.
Maybe someone can explain what the difference between file and
assembly is in terms of a final exe file?
Thanks,
Zytan

You can create so called multi-module assemblies, where one assembly
spans over more than one executable file. It's not that common, but in
such a scenario you'd have a single assembly version while each
executable could have its own file version.

Hello,
I am trying to use vs.net 2005 to migrate a project originally in vs.net
2003. I started with creation of a "web site", and then created folders for
each component of the site.
I read somewhere that each folder under the "web site" is compiled in
separate assembly. I however, did not find that the "web site" creation in
vs.net 2005 created any AssemblyInfo.cs file.

In VS.2005 using VB.NET
There are two versions on every project, The Assembly Version

Why are there two different versions?
As far as I can tell, there is not need for two versions.
The assembly is the file, isn't it?
