Note : I don't have root permission in my Linux box.
I need to compile a .NET (visual studio executable) solution file in my Linux machine.
I have just heard about a way that Microsoft is providing an extension to perform the same like mono, Yocto, etc.,
What are the possible ways that i can run the solution?
Can someone please tel me how do i do it?
the .NET framework has been made open source, but there is not official release yet for Linux. The development community for Linux would be the one most likely to make the tools.
Excerpt from Microsoft Site: .NET Core is Open Source
Today (Nov. 12, 2014) is a huge day for .NET! We’re happy to announce
that .NET Core will be open source, including the runtime as well as
the framework libraries.
This is a natural progression of our open source efforts, which
already covers the managed compilers (C#, VB, and F#) as well as
ASP.NET:
C# & Visual Basic ("Roslyn")
Visual F# Tools
ASP.NET 5
Entity Framework
This takes it to the next level by extending it to the .NET runtime
and the core framework.

I have a C# program which I want to make available to my users, but the problem is that it requires .NET framework version 4.0. This is a problem because it was released pretty recently (April 2010) and a lot of people probably don't have it. To make matters worse it takes a while to download and install the framework (~10 minutes).
Is there any way I can install just a part of the framework I need? If that isn't possible can I compile my code down to a native binary for specific systems
eg. x86 32-bit, x86 64-bit, etc.
I've looked at a company called 'spoon' http://spoon.net/ but that looks like it just emulates apps on a server (sort of like citrix). What can I do to resolve this dilemma?
Anyone who wants to run your program needs the appropriate version of the .NET Framework installed. There's no way to work around this. It honestly amazes me how often this question gets asked. You can't compile .NET code down to any kind of a "native binary", and you can't distribute only the portions of the framework that you need. If all of this was important to you, you should have chosen a different development platform in the beginning.
Your only option is to bundle the .NET Framework along with your application's installer. The way to make this easiest on your customers is to use Visual Studio to create a setup project that will automatically install the .NET FW if they don't have it already, and then install your application, all in a single step process.
Visual Studio has built-in support for creating such a setup project, and most of the dirty work is handled for you. File -> New Project -> Other Project Types -> Setup & Deployment -> Visual Studio Installer. Then, pick either the "Setup Project" or "Setup Wizard" option, and follow the instructions.
The only thing to keep in mind since you've developed for .NET 4.0 is that there are two versions of this framework: the full version and the "Client Profile". The Client Profile is an attempt to do exactly as you mention and install only the portions of the framework that are used by the typical application. You have to first figure out of this is a deployment option for you. If your program uses classes that are not available in the Client Profile, you need to install the full version. Otherwise, you can consider installing the Client Profile, which is the default for all new projects targeting .NET 4.0 in VS 2010. Check the "Target Framework" settings for your application, under the project Properties. If it's not set to Client Profile already, try changing it and see if it will compile. That's the quickest way to tell if this deployment option is available to you. But there's only about a 15% difference in size between the two frameworks, so it isn't really that big of a deal if you must deploy the full version.
Either way, the setup project will automatically determine and bundle the correct version for your app. Definitely don't make the user download and run the .NET installer separately. Use the setup project and do this for them automatically. If you don't have VS or don't want to use the one it provides, investigate alternatives, like Inno Setup, which also support deploying and installing the .NET runtime with an app.
In many cases you do not need the entire .NET Framework 4.0 and can use the much smaller .NET Framework Client Profile. You can then use an installer to bundle the client profile installer with your app into a single deployment.
You cannot run a .NET app without the framework. If this is a deployment issue for your customers, you should consider either a Click-Once installer (web-based automated installation and updating) or porting the app to Silverlight.
For the sake of completeness, there is also the possibility for .NET Core release deploy Self-Contained Deployments (SCD) nowadays. When you create a self-contained deployment, .NET Core tools automatically include the latest serviced runtime of the .NET Core version that your application targets.
Deploying a Self-contained deployment has two major advantages:
You have sole control of the version of .NET Core that is deployed with your app. .NET Core can be serviced only by you.
You can be assured that the target system can run your .NET Core app, since you're providing the version of .NET Core that it will run on.
Here is a small guide from Scott Hanselman.
I am interested in C# windows application development. But now that I have shifted to Ubuntu I am no longer able to do it. Is there a way other than virtual box to develop a C# windows application in ubuntu??
Well there's the Mono Project but if you want the Microsoft .NET implementation you need Windows.
You might be interested in Mono Project.
It is an open source, cross-platform, implementation of C# and the CLR that is binary compatible with Microsoft.NET. However Mono is not totally up-to-date with lates releases of .NET Framework. It is a mix of .NET 2.0 - .NET 4.0 features.
The Mono project focuses on compilers and runtime libraries and does not directly provide an IDE like Visual Studio. Check here to check available solutions.
I intend to learn C# and start coding Windows .exe applications, but the only thing that is holding me back is that not all potential users have the .NET framework installed and therefore would be unable to run my application.
Is there any way around it?
Thanks!
No. c# only target .NET (or a comparable framework, such as mono). As an aside, Win7 comes with .NET preinstalled, and I believe Vista did as well. There are also a ton of MS apps which require .NET. It's getting near ubiquitous on windows machines, so I wouldn't worry about it.
YES, there was XenoCode that can wrap everything that your app needs and runs it in as a standalone. I don't know what kind of dirty tricks they use, but there IS a way.
Now it's Spoon
From their site:
Spoon Studio
Easily virtualize all of your applications for instant,
zero-install delivery on Spoon Server and Spoon.net.
Spoon Studio lets you convert your existing software applications into virtual applications
that run with no installs, conflicts, or dependencies.
BTW, I'm in no way affiliated with them - just curious if the community will accept it or flame it.
Yes, with .NET Native.
Instead of compiling to intermediate language, it will compile to native code and run with statically linked .NET libraries. Therefore, there will be no .NET Runtime requirements for end users.

Does not work before Windows 10
C# is just a programming language. From a strictly technical point of view, someone could develop a C# compiler that targets the Windows API or <insert your target platform here> directly. Sure, it would be a lot of effort because C# was designed to fit .NET, which means the compiler writer would essentially have to re-implement .NET to provide all C# features.
From a practical point of view, you just want to use C# to target either .NET or Mono.
Microsoft started shipping .NET 2.0 with XP since 2005. So, even if your target machine was bought somewhere within the last 8 years, it should still have .NET.
If you are targetting the linux machines on the other hand, there is the mono framework available for that. You don't even have to include it, most repositories like ubuntu, debian, etc. has packages available for mono in their repositories. All you have to do is make your own package dependent on Mono runtime.
NO as simple as that
Everybody might say that it is already installed/ or you need the runtime. But that means YOU NEED IT
It's not about C#. It's about whether you want to develop managed or unmanaged applications. C# is the choice for developing managed applications which run on .NET Framework.
If you want to avoid it, you can go to Visual C++ (without .NET) development using Visual Studio
However, .NET framework comes pre-installed with latest Os like Win 7 these days.
Microsoft makes a redistributable installer that installs the version of .NET that you require. It bloats your install, but it's pretty much the only way to do what you need.
You'll need the .NET Runtime. However, most of the PCs running windows already have it.
Hey guys - I just wrote an app using c# and ready to deploy it. Never deployed a c# app before.
I deployed it and VC# outputted a .application file, application folder, and an installer. One of my users ran the installer (Windows 7) and was prompted to download/install the .net framework - which took upwards of 10 minutes. This is not acceptable for how simple my app is.
Moreover, I will need this app to be able to run on mac osx and linux if possible. Should I have wrote this in Java instead (poor planning on my part). What are my options?
C# is compiled to bytecode that runs on the CLR, the virtual machine that's at the core of the .NET framework. So yes, you need the .NET framework to run that.
Most current versions of Windows (XP, Vista, 7, etc.) come with some version of the .NET framework pre-installed, so your users don't have to download and install it. However, you might have used a version that's not already installed on the computers of (some of) your users.
For Linux and Mac OS X there is Mono, which is an open source implementation of .NET, but it does not contain everything that Microsoft's .NET contains, so your program might not work fully on Mono.
Using Java is not a real solution in the sense that your users would need to download and install the JRE (Java Runtime Environment) to run Java programs, very similar to the .NET framework. An advantage if you'd have used Java, is that Java is much more cross-platform compatible than .NET (Microsoft has no real interest in making .NET run on anything else than Windows).
.NET apps require the .NET framework. Java apps require the JRE. Your app is simple because .NET has done a lot of the work for you. A lot of companies write desktop apps in C++, but you will have to be mindful of cross-platform issues.
Yes, with any language that compiles to run on a managed runtime (.NET or Mono CLR, Java JVM) you will need to have that runtime installed. A C# application can compile to run on Windows on the .NET CLR, or on all the platforms you mention to run on the Mono runtime instead. Alternatively, a Java application would compile to run on the Java JRE, which is also compatible with all the platforms you mention.
So with either language there is potentially this extra installation overhead, and with either language you can achieve what you want.
You'll need to have .NET installed on your client's system in order to use your application.
As for running cross-platform - depending on how your Application is written, this can be simple or difficult.
You may want to look at Silverlight. This is directly supported on OS X and works on Linux via Moonlight.
Another alternative is to use Mono to run your .NET application on other platforms.
A C# app will need an implementation of the CLR (.NET) running on the local machine in order to run. A Java app will need an implementation of the JVM so it is really no different. On Windows, I would expect most people to have a .NET install.
Take a look at the Mono project as far as running it on Linux and Mac:
http://mono-project.com/Main_Page
One thing you can consider is using an older version of the .NET framework to ensure that the greatest number of people have it installed. I would use .NET 3.5 or even 2.0 if you do not need fancy new features. That would have been installed already on Windows 7 for example.
Since the Windows 7 user had to download the framework I assume you are currently targeting .NET 4 which means you must be using Visual Studio 2010 (or an express version). Here is a link that tells you how to target a different version of the framework:
http://msdn.microsoft.com/en-us/library/bb398202.aspx
One quick note about Mono, it is an excellent cross-platform option but it does not support the Windows Presentation Foundation (WPF) GUI framework at this point. You will either have to use Windows Forms or create different front-ends for different platforms.
If you want to create a Linux GUI (also available on Windows and Mac) you can try GTK#:
http://www.mono-project.com/GtkSharp
For a Mac native GUI you can check out MonoMac:
http://mjhutchinson.com/journal/2010/06/09/monomac_in_monodevelop
An excellent IDE for cross-platform .NET development is MonoDevelop (it will read your VC# project files):
http://monodevelop.com/
Like Java, .Net languages need a runtime installed. The full .Net framework is sometimes too big for small applications, so there is a smaller version of it call the compact framework with a smaller footprint that will install and download faster. You can read about it at http://msdn.microsoft.com/en-us/netframework/aa497273.aspx. As noted by other answers most current versions of Windows come with various versions of .Net framework, so this installation may not be needed for every user.
As far as your cross platform needs go Mono allows for running .Net applications on Linux, I am not sure about running them on OSX. My assumption is you can not. Unfortunately your cross platform requirements made .Net a bad choice, and you should have gone with Java.
Other people gave you complicated answers. Well here's my simple answer. .NET framework is needed to run .NET applications and so do Java need JVM (as MCain said). Starting with Windows Vista, Microsoft includes .NET Framework built inside Windows. And in addition, .NET have versions, from 1.0 to 4.0. With Vista and Windows 7, .NET 3.5 is installed by default. I think your app is targeted for .NET 4.0 which is why a Windows 7 user needed to install .NET framework. For me, if I have to write a simple program, I'll use .NET 2.0 (later version = larger libraries, etc) so that my users (if they are Vista or Windows 7) don't have to install .NET again to run my software. You can choose which version of .NET you will target from New Project Window in Visual Studio.
You can change the target framework in the properties tab. If you start a project in VS2008 the default is .net 3.5 and for VS2010 it is .net 4.0. If you don't need the advanced features you can change your target back to 2.0 which should be available on most computers by now (I would guess far over 90%). Be sure to remove dependencies which are not available in 2.0 (like System.Linq, System.DataSet.Extensions) and the accociated imports (But the compiler will tell you what to do).
Very blunt and to the point, but does anyone know how to convert a visual studio 2008 project to visual studio 2003, I'm meant to be delivering some stuff to a client and they only work in 2003.
Sorry someone makes a very good point, what language, C# is the answer.
I've done a bunch of searches on Google and tend to only come up with 2003->2008 and not visa versa, I would very much appreciate any help.
It cannot be done in the general case, as the VS2008 project may use .NET 3.5 features that don't exist in .NET 1.1 used in VS2003.
If you only have .NET 1.1 features in your VS2008 project, you could conceivably just copy the files, create a VS2003 project, then use "Add Existing Item" to get those items into the VS2003 project.
2008 has more settings than 2003. So if the project has some special settings your screwed.
Else create a new 2003 project and copy all the source files? (and use the same configuration)
It is going to be very difficult because VS2003 projects use .NET 1.1 and VS2008 use .NET 2.0, 3.0 or 3.5 (depending on the configuration of the project). The problem will be that there are features that have been to each version of the framework, and it is likely the code will use features that do not exist in .NET 1.1
There were converters to go from the old VS2003 project format to the MSBuild format used by 2005/2008, but I don't think any exist to go backward. Keep in mind that any non-trivial project in VS2008 might be challenging to move to VS2003 -- especially for an automated tool. For example, WinForms went through massive changes between VS2003 and VS2005.
Please correct me if I'm wrong, but doesn't Visual Studio 2003 only support .net 1.1? That means that if you have a .net 2.0 or 3.5 Application you have a problem. For C++ I guess it's a similar issue due to the old compiler.
Means: I believe it's borderline-impossible.
