How do you manage a project branch when 3rd party library versionschange?

Uri Dor

Hi,
I'm developing a WinForms C# 1.1 application and am reaching a point at
which my code may face a branch - let's say version 1.1 is released to
end users and we'll continue to fix bugs, but version 1.2 is being
developed.
Now let's say that I decide to upgrade a 3rd party component library I'm
using (I currently use Infragistics, Janus GridEx and Syncfusion
ExcelRW) - will I be able to build version 1.1 with its matching
components and version 1.2 with its matching components (different
versions) on the same build computer configuration?
Where do the assemblies for compilation come from ? The GAC on my build
machine ? I remember playing with this and directly referencing by path
to DLLs that were also installed in the GAC and getting warnings.

Regards
Uri

Often these control vendors uninstall older versions first, if I'm not
mistaken Infragistics does this (and creates a backup folder) and
install newer versions into the GAC.

There's nothing wrong with keeping the assemblies locally to your
project. So create a folder for the 1.1 application and put in there
all assemblies it currently needs. Eventually, store this in source
control as well, or at least be sure you can re-build that folder from
a backup. Then build your 1.1 version with those assemblies and build
1.2 with the newer versions.

I'm not sure how old the infragistics assemblies are you're using, my
experience with 2004.1 is that locally copied assemblies from them
didn't play nice, but required that they were loaded from the gac,
could be some assembly wasn't reachable though didn't get an error,
just weird rendering.

Compiling a Class Library project into multiple assemblies

Hi there, I'm working on developing a large Class Library project that is slowly becoming a shared "framework" library amongst multiple applications. As this shared library grows, I need to start thinking about ways to split this library up. In observing the .net framework, I've noticed that each major branch of the framework (eg. System.Net or System.Data) and even some of the minor branches are split up into individual dlls. When...

Project organization and import

I'm using Python for what is becoming a sizeable project and I'm already running into problems organizing code and importing packages.

How do I add libraries to my vb.net project?

I find that when I compile my project into an exe, that I have several copies of that exe in different places. ...

The project is always out of date.

Hi, guys, I add some new projects. No source file, but only some copy operation in Post Event. The project is to do some file deployment for some third party library. When I compile the solution, VC assumes the project is always out of date and execute the Post Event always. It’s boring, the copy operation will happen always, even if there is no modification in the solution.
