i am a fresher for the linux programing related areas, i want to write a server which will keep long live connection with client site. the reuqirement descritbed this server should be hosted within a linux server.
would anyone please help to share some example or reference for me on how to begin with c# epoll coding?
Thanks in advance.
MonoDevelop, the IDE associated with Mono Project should be enough for C# development on Linux. Now I don't know any good profilers and other tools for C# development on Linux. But then again mind you, that C# is a language more native to windows. You are better developing C# apps for windows than for linux.
EDIT: When you download MonoDevelop from the Ubuntu Software Center, it will contain pretty much everything you need to get started right away (Compiler, Runtime Environment, IDE). If you would like more information, see the following links:

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.
May be this is a question when a programmer/developer thinks to start mobile application development. But he is habitual of a particular environment in which he is working from several years. So it would be more comfortable that he can develop mobile app in the same environment what he is using from years.
I am currently working in Asp.Net MVC with C#, Visual Studio 2013 and i like it most. I am working on a large MIS and want to make available my solution to all platforms. As we know mobile devices are the most powerful technology current days.
Please suggest some way that i can work in visual studio and can develop cross platform mobile application that can work on Android, MAC, Windows Mobile and Windows PC/Laptops
I know there is many tools are available, but i need an expert suggestion on this particular scenario. If you provide a solution then please describe how to enable it in visual studio or how to customize current solution for that.
To have .net apps running on mobile platforms other than microsoft, have a look at xamarin
This is the front office for the mono framework
I know it's probably old question but you can try Apache Cordova with Visual Studio.

Recently I got a new PC with Windows 7 and installed C# 2010 Express. I have a LOT of software I wrote on my Vista machine in C# 2008 Express. When I tried to migrate the managed D3D apps to 2010, they all crashed on run with an error "is not a valid Win32 application." and after some troubleshooting I learned it's because MS no longer supports managed DirectX. What a drag. So it looks like I'll have to rewrite a ton of code to use one of the following alternatives:
*XNA
*Direct3D 10/11 API (like you would use in VC++)
*OpenGL
*Some other option, like maybe SlimDX
I'm looking for a solution that is:
*Backwards-compatible (ie, Vista and XP)
*Forwards compatible (I don't want to learn a new system just to have to drop it and learn another one in a year)
*OO-friendly -- I have thousands of lines of code to rewrite. I don't have a problem writing unmanaged code, but a similar OO solution would probably reduce the porting time.
I can't be the first person to run into this issue. What are some solutions other people found?
My guess would be that your applications are built as AnyCPU, referencing x86 assemblies, but your Win7 machine is x64. Building your applications as x86 might solve the issue.
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
