I have a few console apps that I want to run on a dedicated box. However, I have no interest in purchasing a windows license.
Is there anything special I have to do after compiling the code to run on linux mint?
Normally, you'd install mono

http://community.linuxmint.com/software/view/mono-complete
The most popular package for developers seems to be
http://community.linuxmint.com/software/view/monodevelop
With existing console applications, there will be no need to recompile (.NET is platform indepent, remember?). However, there could be slight incompatibilities to missing support for very specific Microsoft Class libraries (think of WPF, till recently Message Queues, some Winforms Stuff and obvious Interop (P/Invokes of native libraries).
Use the Moma tool to scan for such incompatibilities, and you'll get a nice overview of things that might cause a problem.
Just compile your code using the Mono compiler and you should be good, if it's a simple console app.
Assuming you have Mono installed on the Linux box and you don't use anything MS-specific, then no, you don't have to do anything special. Just compile the .exe, copy it to the linux box and run it using mono the_app.exe.

Is it possible to develop and build Linux applications with Xamarin with the same code base?
After a few years with Ubuntu, my main OS right now is Windows again. But it's not impossible that I could switch to Mac.
Right now I have a bit of experience with Qt and no experience with Xamarin.
With Qt you can develop on Windows, Linux, and Mac and for Windows, Linux, Mac, iOS, Android, Windows Mobile, ... They are pretty clear about that.
Since Xamarin is free and open source now and I still don't have much experience in Qt, I'm considering trying out Xamarin for cross platform development instead of Qt.
Not being able to release my software for Linux would be a deal breaker for me. Being able to develop on Linux would be nice, but is optional.
But after all my Google research, I could only find information and people asking for support to develop on Linux and not for Linux.
As far as I know, this shouldn't be a problem with Mono alone. But as far as I know Xamarin > Mono and I don't get everything in Mono I could get in Xamarin.
I'm also not sure how well-supported Mono will be in the future. For me it looks like Xamarin is much more important for Microsoft than Mono itself.
I'm not sure if it's even possible, since Xamarin is based on Mono, but is it possible that Microsoft will at some point decide not to support Mono with .NET compatibility in the same way as Xamarin, or even cancel Mono as standalone completely?
So I'm looking for one single framework for all desktop and mobile platforms I can rely on, and I want to know if Xamarin and/or Mono and and/or Xamarin + Mono could be an alternative to Qt before I go deeper into any of those solutions.
Just in case someone else comes accross this q/a: the situation has changed. With Xamarin.Forms 3.0, Gtk# is supported (as preview, at this moment). Therefore, full Linux GUI support is enabled.
So, Xamarin now covers:
Android
iOS
UWP apps
WPF apps
Linux Gtk desktop applications
Mac OS
Watch OS
tv OS
Tizen
The only thing left to wish for: JS/HTML5 Web App target platform, as part of Xamarin :)
No, Xamarin is not available for Linux. This was a conscious decision made by the Xamarin team several years ago:
Miguel de Icaza 2011-08-04 11:52:37 UTC
We face a QA problem here.
The problem with supporting Linux is that we would need to create a
self-contained Mono packaging for all of the bits we ship since most
Linux distributions are slightly off when it comes to Mono.
It also means that if we advertise "Linux" we would need to QA a dozen
different combination due to different Linux distributions and
different editions of each distribution.
Perhaps we would support just a single distribution and a single
version, which is closer to what we have to do on Windows/Mac today.
To clarify, the Xamarin product range is not available on Linux (Xamarin Studio, Xamarin.iOS and Xamarin.Android) but MonoDevelop, the foundation of Xamarin Studio, and Mono, the cross-platform .NET runtime, definitely is.
You can build desktop software using MonoDevelop. The MonoDevelop site has plenty of instructions on getting started:
Install MonoDevelop on Linux
Seems that there is a chance of Xamarin Forms work on linux distros. In this reddit thread Miguel de Icaza says:
Some of our team members actually develop in Linux. The reason why we
never released the Linux tools is because we were charging a lot of
money and people would rightfully expect the software to be fully
supported. We had enough keeping our Mac and Windows users happy, and
adding an unknown number of Linux distributions sounded like a hard
task. Now that we are open sourcing the SDKs and I no longer will feel
bad if something does not work under a particular Linux configuration,
I will be happy to release the Linux builds.
That is: the fact that Forms is an open source tool currently opens this possibility.
Yes, as of mid-2018, it is possible to develop cross platform GUI applications that target windows/mac/linux/android/ios using the "Xamarin.Forms" library. Basically, you have one shared library project from cross platform code (UI and other cross platform stuff), and one project per platform for platform-specific code (Xamarin.Forms have one backend implementation for each platform. On Linux, this is using GTK).
However, with MonoDevelop you can only develop/build the cross-platform project and the linux-specific project of the application. You will still need to use Visual Studio or Rider to develop/build for the other platforms.
See the following answer:

As matthewrdev said, Xamarin.Studio, Xamarin.iOS, and Xamarin.Android aren't "officially" supported; however, Xamarin.iOS uses virtual emulator anyway (and I don't think there will be a workaround for Xamarin.iOS to run on Linux), but for Xamarin Studio (MonoDevelop on Linux, or Jetbrain's Riders (how to run it on linux with no official support is also provided in the link) Can run on Linux as an alt for Xamarin.Studio, and that link I shared explains how to install Xamarin.Android on linux, so just for Xamarin.iOS you will need to migrate or dual boot or sth, I hope that helps! (I stopped using Xamarin my-self, however, this environment helps developing for Xamarin on linux!)
GTK is listed as one of supported platforms/backends for Xamarin.Forms which allows building apps for Linux (as well as macOS and Windows via same GTK project). Though it doesn't look like there was much of development since 2018/2019 and Xamarin.Forms 3.0. Tried running 2 apps with basic UI and compared GTK backedn on Windows/macOS (comparing to WPF and Xamarin.mac back-ends ) and found GTK not worth pursuing (basic scenarios failing).
You can track GTK progress at https://github.com/jsuarezruiz/forms-gtk-progress/blob/master/Status.md
On Ubuntu 20.04, you can run your ASP.Net MVC 5 application using XSP4. Open a console to where you installed your MVC applications, where all folders, Global.asax, Web.config, ... are and run "xsp4 --port 80" or any other port you like and available. XSP4 is an independent web server and does not need Apache to be run.
Also, for C# developers, even the MonoDevelop is not in Ubuntu 20.04, which I don't know why, you can still install it and debug your ASP.Net MVC application. You can also debug any WinForm and console application using the MonoDevelop. YOu can run all your application using mono too.
I am writing a portable service/daemon using .NET 3.5, my windows service is running, but I was wondering about the mono port...
Mono-service is what I am looking for if I understand correctly. How exactly does this work though? I assume I need mono compatible code throughout my service, right? For example, I am using SQLite. Is it correct that in order to use this with mono I should refactor my code to use mono namespaces etc, such as Mono.Data.SQLite? May I still use Settings.settings?
Also, I've read that daemons don't implement onStart/Stop methods, so do I need to change my code to run under mono/linux? i.e. is it ok to have these methods in my code, and ok to run ServiceBase.Run()? Does Mono-service accommodate these?
You should create your programs from the beginning for use with Windows and Linux.
You need Visual Studio with Mono Tools or the free MonoDevelop-IDE to create a Mono-Application. MonoDevelop can import your Visual Studio Project. This IDE helps you to get the right namespaces.
Use Mono-Service to run your Assembly as daemon. Linux Daemons are using Signals to communicate with the System. Please read the documentation.
We already had a similar question, so please read this to see, how to process Unix-Signals.
I developed a winform application using C# in visual studio 2008. Now i want to run the exe on another PC which doesn't have .net framework or Visual Studio. I am sending the application using Zip via email. The second PC downloads that application and extracts into a normal folder and then it executes the exe file.
But i am getting the exception that .net frame work v 2.0 must be installed.
Can you please tell me how to run that exe without .net frame work installed?
(Amended for #Merhdad's sanity :-))
The short answer: You can. You shouldn't.
The long answer: You could technically create your own unmanaged bootstrapper that goes and download the .NET client profile redist and silently installs it using the MSI APIs, and then loads the CLR and hosts it in the process in order to execute the managed code, after which it silently uninstalls the .NET Framework from the machine.
The Disclaimer: I know few people that could pull that off. They would be the first to tell you not to do it.
The alternative hack answer: You can also use one of the tools #Mehrdad mentioned. i can't comment whether they work or not. However, you should be aware that this leaves your app linked to a specific snapshot of the .Net framework code, and for every security update you need to take, yuo have to relink and release an update of your application as well.
The alternative open source answer: You could ensure your WinForms app builds and runs on Mono, and deploy Mono side-by-side with the app. I've heard it supports that scenario.
The alternative IT answer: You could create a VM appliance with stripped down Window image that has .Net and your app only, and ship it as a single executable.
The right answer: Create an installer for your app that installs the .NET Framework for your customers.
Yes! You can do this with a variety of programs, and Spoon seems to be among the most up-to-date ones.
(Of course, this doesn't mean that you should, just that you can.)
This cannot be done. You must have the .NET Framework in order to run the application.
I solved the problem.I added a package in visual studio.I added Setup and deployment as a new project to my solution.later i added exe to that package.so if client machine runs the setup it'l create exe and can run the application successfully.
yeah,you can do that by converting your whole application to an installer.just check it out, it will helps u a lot

I am currently working in C/C++ in a Unix environment and am new to Linux environments. I would like to learn about the Linux OS and learn C# as the next level of programming language for my career.
I decided to put Ubuntu Linux on my laptop. But I am not sure whether we can write, compile and run C# programs in Linux environments or not.
The only IDE I know for C# is MS Visual Studio. Is there are any possible way to work in C# in a Linux environment?
If I have no other option, I'll have both operating systems on my laptop - Vista to learn C# and Linux for the other OS.
Learn Mono.
The Mono Project is an open
development initiative sponsored by
Novell to develop an open source, UNIX
version of the Microsoft .NET
development platform. Its objective is
to enable UNIX developers to build and
deploy cross-platform .NET
Applications. The project implements
various technologies developed by
Microsoft that have now been submitted
to the ECMA for standardization.
You can use the MonoDevelop IDE.
MonoDevelop is a free GNOME IDE
primarily designed for C# and other
.NET languages.
Mono is an open source .NET compiler, runtime and library.
Monodevelop is an open source C# IDE, primarily intended for linux development. It includes a GUI designer.
You can also use wine, which is a free implementation of Windows' API.
For this :
sudo apt-get install wine
then you'll be able to run Microsoft applications and do [almost] everything you like.
EDIT : My mistake, Visual Studio is not functional :-(
A Vista virtual machine in seamless mode running Visual Studio? Then it will appear to integrate into your desktop like any other app, but you'll have the benefit of running the real MS stuff (with C#, having real MS is still a benefit rather than a liability).
I know this is an old question, but I see no one has mentioned Microsoft Visual Studio Code IDE. This could be what you are looking for if you want to do C# in Linux. As a relative NOOB I can say it brings Visual Studio to Linux. If you need a GUI IDE in Linux, this was it for me. see instructions to install it here
I'm looking to spend a bit of my lunch break each day teaching myself some C#. I have access to some books on the subject via my employer-paid Books24x7 subscription, but I have no way of running code while I'm at work.
My work PC is rather locked down (no admin privileges, read-only "Program Files" - though install to a desktop-based folder is possible, and USB thumbdrives are forbidden..), so I'm looking for another way to compile some code.
Can anyone point to:
* A web-based compiler (binary download from a known-good site, or possibly a web-based CLI to interact with non-GUI apps)
* A standalone compiler requiring no-install
* A compiler which does not require admin right to install.
Thanks!
[Edit 1]
I suppose another reason why I mentioned the web-based compiler first was that I'm not sure which version(s) of the .Net framework might be installed on my work machine. We do absolutely no .Net work on my project so there's no reason to believe there's anything more than what came with XP. If there's a way to install the latest version without admin privileges, I'd love to hear it!
If you have the .Net Framework installed on your computer, then you should already have a compiler.
It will be in C:\Windows\Microsoft.NET\Framework\[VERSION]\
It's called csc.exe.
This should work without any administrator priviledges.
There's ideone.com.
It can compile and server-side run several languages that usually require the language to be installed on the client's PC. For me, I can write and run any C# applications without having Visual Studio or the latest .NET Framework installed.
