On Windows 7, VB.NET Express, I have developed a simple Forms application. I don't really make use of any external plugins or anything - it just has a couple buttons, pictureboxes, GDI operations to modify some images...
And now it is complete. And I would like to already upload it. But, since this is actually the first time I try to submit something, what other details should I keep in mind when distributing my application? I mean stuff like... will my application work as expected in other machines? Other Windows versions? I am not in a proper position to test it in other machines, I fear, so I am relying the "default" settings and hoping it will simply work.

Unless you use platform-specific APIs (which are rare in your typical, garden-variety .NET application) then it should work on all versions of Windows that support your version of the .NET Framework. If the end user doesn't have that version of the .NET Framework installed, then he or she will need to get it manually. You can make that a little easier by using the built-in ClickOnce installer (Build > Publish <project name>) if you're not already using it.
Apart from that, no, there shouldn't be any problems, given that you say your application is a simple one. (And console applications can even work on Linux and Mac using Mono!)

I know it's possible to mix C with Go, but I was wondering if it was possible to mix with other languages too. Specifically, I was wondering if it was possible to write a backend in Go and then use Swift or C# to make a GUI for a desktop app.
Also, is it common to build apps like that? What are the performance costs like? The goal is to write a cross-platform backend, then use native platform tools to create the GUI. So, I would use Swift and Cocoa to make a GUI for OS X and C# and .NET to make a GUI for Windows. That way the applications behave and feel like native apps.
Not in the same sense of using C/C++ with Go, no, however nothing is stopping you from writing the backend in Go and controlling it over http (or stdin/stdout).

I want to make a quite simple application in multiple devices using xamarin (iOS and Android).
So I read/think that the best way to doing this is to put one folder (shared between all projects) that contains all the:
DataLayer (for physical storage)
DataAccessLayer (support data operations)
ServiceAccesslayout (communicate with an external API)
BusinessLayer (Application Facade)
And for the view, the applications will use their custom language
So first question, does it sound great?
Second: How add that kind of folder, that should be updated in every project in Visual Studio 2012? Actually I have one solution with two projects and the two projects (iOS and Android) should have that same folter (tat contains all the "core" layers)
By the way if you have already read a tutorial that talk over that question, please give it to me.
I would have a look at MVVMCross, it is a great way of sharing the maximum amount of code across platforms.

i'm thinking about programming a tool that would be useful in windows and mac (as we use those at work) and it's 100% necessary that is inside on a OS window.
The first thing that came to my mind was to use java - as it's cross platform - but, is there any alternative to program cross platform window based programs?
Has anyone tried to use C# windows forms with Mono in other OS's?
I'm interested in a garbage collected language if possible as I don't want to think about possible memory leaks for a tool that can be slower or faster without any trouble.
Also if it's possible to be as easy as it is in visual studio + C# it would be awesome!
Any idea will be appreciated, thanks!
Java is fine if you're comfortable with it.
Many languages have bindings to cross-platform toolkits: for example Python is very pleasant and has PyQt4 or WxPython, both of which can be used to make GUIs which work nicely on Windows or Mac.
In the manage-your-memory world, using Qt from within C++ is actually very pleasant (they have a nice API). I find it creates more elegant applications than my Java code (they feel a tad more native) though YMMV.

I'm toying with the idea of building a Cocoa app that uses OpenCV. I could take the easy route and just use MacPorts or some such tool to get OpenCV quickly. Unfortunately, sooner or later, I'd still have to tackle the issue of deployment so I decided to get that out of the way immediately.
My Question is:
What is the best strategy for deploying apps that rely upon libraries that do not ship with OS X?? Especially with regard to guaranteeing backward compatibility to OS X 10.5 or even 10.4?
The way I see it these are the options:
I could compile OpenCV from source as dynamic libraries and install
them on the customer's computer using an installer.
I could compile OpenCV statically and embed the static libraries in
the application bundle.
Then there is the option of creating a Private Framework but nobody seems to
have a clue about how to do that.
I'm leaning towards option 2 since I like the idea of distributing the app in a *.dmg image since that reduces installation to simply draging-and-dropping the app bundle to the 'Applications' folder.
I think Option 2 is Apple's recommended choice.

I was wondering it for a long time since Apple released iTunes for Windows. What did they use to write iTunes for Windows? It seems completely with its own UI components and everything is contained inside it. It even uses QuickTime resources files. Can we assume that they've Cocoa working with windows. Anyway, my main question is, is there any known (public or private) tool/language/framework used in developing iTunes for Windows?
Not a direct answer, but if the reason you're asking is that you want to port a cocoa application to Windows, you might be interested in this:

Haven't used it myself, but I gather they've got enough done to make a useable cross-platform Cocoa app.
itunes for both mac and windows are written in c++ as it is easier to port between operating systems with much or the same codebase
