I'm a student and at the moment i'm doing an internship at a company. This internship is about analysing a project. For this project I have made a demo to show to the Marketing director. The demo I have made is a simple project created in Visual Studio 2010 in c# with Windows Forms and a connection to an Access database.
So now i have to show this demo to this director in a presentation but after this presentation the director wants the project on his computer so he can try and use it. The problem is now that the computers here in this company don't have .NET framework 4.0 and the computers are so protected over here that we can't install anything new. To install something you have to go through a procedure that takes weeks.
I have looked al over the internet but all i find is how to install the .NET framework.
Is there any possible way that I can create an standalone exe without the need to install .NET framework? Please help!
If you want to execute an application that is developed using Net Framework 4, you will need to have installed .Net Framework 4 on client computer.
Your application is compiled in CIL (Common Intermediate Language), so it needs to be interpreted by the framework engine.
It is the same if you want to execute a Java program. You will have to install the Java Machine.
The only way you don't need to install frameworks is programming native applications with C, C++.
C# now supports this 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.

Only works for Windows 10
You can't build a C# executable without .NET Framework. Even if some resources indicate that you can, that only works in theory.
But you could use an older version of .NET Framework like .NET 4.0. If this doesn't work for you, you have to choose a language like C++ which doesn't require CLR at all.
Update 2018:
Do not target .NET 2.0 or 3.5. It's not compatible with the 4.x version. However, .NET 4.0 targeted binaries work with .NET Framework 4.0, 4.5, 4.6, 4.7 and so on. So to reach maximum compatibility, compile with .NET 4.0. You will have to accept that some features will not be available, however, your binary will run virtually anywhere.
(2018: By now, .NET 2.0 - 3.5 has much lower distribution than 4.x)
Delphi is your solution, deploy native bin executables
YES, THIS IS POSSIBLE!
At least 3 ways exist:
1.you can check all OSes that you planning to run your app and build with such version of .NET. As Windows have a built-in framework libs.
Vista -.NET v3.0 -- All service packs
Windows 7 - .NET v3.5 -- All versions and service packs
Windows 8 - .NET v4.0 [Best choice if you are not sure]
Windows 8.1 - .Net v4.5
Windows 10 - .Net v4.6
as they are already pre-installed by default -- no extra install will be needed.
2.For windows 10 you can compile it into native code (but not into CIL) with ".NET Native". This is means that there are no .Net Framework will be needed for apps.
3.There is Turbo Studio (earlier Spoon and earlier XenoCode) that can wrap everything that your app needs and runs it in as a standalone.
From their site:
Turbo Studio
Run .NET Without .NET. Easily embed runtime dependencies such as .NET, Java, and SQL directly into virtual applications. Launch reliably on any desktop, regardless of underlying component installs.
You can use Mono and statically link you program, so your program don't need .NET CLR runtime and act as standalone program.
Mono Project
In more modern versions of .NET such as 5 and 6 and even with releases of .NET Core it had become a supported scenario to produce what is referred to as a single-file executable as well as a self-contained application.
As I understand it, these technologies take place of and build upon some of the capabilities that had been in the Mono development stack for a while now. Typically I've seen this feature used for applications which would be deployed to servers such as web sites and microservices however it could be used for scenarios such as the one that the original poster illustrates.
Using the .NET SDK publishing (producing the executable) for a single-file executable can be done using a command as the one below which comes directly from the documentation.
dotnet publish -r win-x64 -p:PublishSingleFile=true --self-contained true
For more details see Single file deployment and executable in the Microsoft .NET documentation site.
To be honest, it really isnt a problem nowadays. the .NET framework is found on almost every single computer nowadays, and you can even make a installer with Advanced Installer that silently install the .NET framework on your computer when you are installing the programme.

I asked this before but if i downgrade to .NET 3.5 I am not able to do some things with the windows form application I get errors because some things that have been added in later versions are not in the version that I am using.
I am making the application for Windows 7.
Link to previous: Can you launch a app C# so it doesn't need the .NET
As C# is essentialy a human-readable version of .NET's intermediate language (IL) you cannot run an application created using C# without .NET runtime installed.
You don't need to downgrade anything - just change target version to 3.5. However, you'll have to stick to features of 3.5 and below in that case.
If you want to use 4.0+ - just make an installer for your app which installs .NET 4.0 runtime alongside.
P.S.
I personally really doubt that there is noticable count of boxes running Windows 7 without at least .NET 4.0.
Just include the required Framework for your application in the Installer. They should be able to run side-by-side.
I have created a new application on C# 2010. After creating a Setup file I came to know that for installation purposes user must have a dot net framework. Is there any way I can get rid of installing dot net framework on a user computer. Each time I try to install my application on the user computer it redirects to install the dot net framework. Any suggestion?
Well that's a problem; because of the design of .NET applications.
Here's some references for you:
Visual C#
"C# (pronounced "C sharp") is a programming language that is designed for building a variety of applications that run on the .NET Framework." [first sentence]
Intro to C# and .NET
As the comments on the question attempt to imply, the .NET Framework is required in order to execute .NET applications.
You have two choices, really:
Require that users have the .NET Framework installed. This is the most common choice, for reasons that will become clear in a moment. It's not unheard-of to have such requirements. It's similar to requiring that a user have Windows installed in order to run your Windows application.
Distribute the .NET Framework with your application installer. This is possible, but less often used because the .NET Framework is large compared to the average application. However, if you must do this, then the option is at least available. Some quick Googling brought me to this helpful blog post.
This isn't possible. C# is built on the .NET framework, so any C# app requires that a version of .NET be available. At http://en.wikipedia.org/wiki/.NET_Framework#History, you can see what .NET framework versions are available in various versions of Windows. The short story is that XP doesn't include anything, Vista includes 3.0, and Windows 7 includes 3.5. If you build for one of these versions, then on those OSes, your users won't need to install anything extra. Using the Client Profile instead of the full .NET can also help reduce or eliminate installs your users will need to do.
Unfortunately No. Its not possible.
To explain it simple terms.
Suppose if you have written only 1 Line of code where you would have simply declared an int variable, who will tell OS that it should create a space in memory?
That framework does exactly that creates basic environment to run your app in a System.
OOPs says about Real-world modeling and Relationships, so let me give you one from it.
Think yourself to be the C# app and Mother Nature/Environment(Greenry) to be .Net Environment.(.Net is called an Environment)
Can you survive without mother nature? From first second that you are in this world, you breathe. Who provides you that oxygen. MOTHER NATURE
While creating installation bundle you can add dot net frame work exe file as prerequisites, then while installing your application it can check whether the system having .net framework or not. if it is not installed it your application can install the frame work.
When you are using managed languages to writing applications you agreed to use their vm, c# codes compiles to IL which needs dot net framework for executing.
.net framework by default exists on windows 7,8,8.1 and 10 and I don't think that this is a challenge.
but if you insist on it so there is a way by using Mono, just remove features that does not support in mono from your project.
first install mono and cygwin, then copy your exe and mono.dll file to a folder, be sure that your file name is not long because in some cases bundling faild,now you can start bundling using mkbundle command.
after bundling finished you have a exe file that can run without .net framework
hope this help you
I have the same issue and want the app to setup using the existing dot net framework version (4.6), because the app setup requires 4.7.2 version that the PC doesn't meet the requirements
I am very much worried that i have seen many applications which i download from internet and they run without installing .net framework or java run time on windows seven, the confusion is, if it is so then in which language all these applications are built? if it is VB6 then it is very old, why latest software are using it, and did Microsoft not build Windows seven in any .net framework, for example if they build it in 3.5 then why it requires to install 3.5 .Net framework to run application.
Also let me know which db these apps usually use.
They could be built using C or C++, or any number of other languages with no runtime libraries (or whose runtime libraries are built into the OS). They may also just use .NET and assume that clients have the .NET framework installed. Finally, they may actually check for the .NET framework and prompt the user to install it if it isn't there, but since you already have it installed you don't see the prompt.
As for which databases they use, it is common to see applications use SQL Server CE or Express, Berkeley DB (BDB), or any number of other small-footprint databases. There is no clear winner in that area, just like in programming languages.
Mostly, Windows 7 has the built-in .NET framework 3.5 So, it automatically runs the application developed in .NET, where as few earlier version of Windows OS, the user didn't have the needed framework in built. It needs to be installed separately.
I want to develop a small utility for windows and I prefer doing that in c# because it is easier (I'm a java developer).
The utility will be available for download by many people and I assume some of them will not have the .net framework installed (is this assumption correct, say I target win xp and above?)
My question is: can a c# application be compiled in a way that it will not require the .net framework installed?
Normally, you will need the .NET Framework being installed on the target system. There is no simple way around that.
However, certain third-party tools such as Xenocode or Salamander allow you to create stand-alone applications. See this related question:
Is there some way to compile a .NET application to native code?
As these solutions are not straight-forward and require commercial products I would recommend you to create a simple Visual Studio Setup and Deployment project. In the properties of the project you should include the .NET Framework as a pre-requisite. The setup.exe created will then automatically download and install the .NET Framework prior to installing your application.
No, it will need the .Net framework installed. Note though that you will need only the redistributable version, not the SDK.
A minor aside - but in this scenario, consider developing the utility in Silverlight - it has a much smaller footprint and is supported on a number of operating systems. This might allow you to get the coverage including people who don't already have .NET.
If you need "normal" .NET, then "Client Profile" is perhaps an option.
You can probably also include the .net framework installer in your application.
In a related question, Can you compile C# without using the .Net framework?, it's mentioned you could do this using mkbundle from mono. I haven't tried it myself so I can't comment on if it's the way you should go, but you may want to consider it.
How do I only include certain dlls of the .Net framework which are used in my program along with the setup project instead of installing the whole framework?
Thanks
You want to deploy a .NET Application to a server, that doesn't have .NET installed and only have it install the specific System.* dlls required for you're application ?
I'd be pretty sure that you can't do this. There's more to the Framework than just a bunch of DLLs in the GAC. (e.g. CLR, registry entries etc...). You'll need to install the framework on the client machine
I would recommend the .NET Client Profile, described here. "The .NET Framework Client Profile is a subset of the full .NET Framework 3.5 SP1 that targets client applications. It provides a streamlined subset of Windows Presentation Foundation (WPF), Windows Forms, Windows Communication Foundation (WCF), and ClickOnce features. This enables rapid deployment scenarios for WPF, Windows Forms, WCF, and console applications that target the .NET Framework Client Profile."
I'm pretty sure that can't be done. C# is managed code, and therefore needs the CLR and the framework to support it.
Unlike other languages that get compiled to binary, .NET code gets compiled to MSIL (Microsoft Intermediate Language), so it cannot be run directly by the hardware.
Since .Net 3.5 SP1 there has been the option of using the .NET Framework Client Profile. This enables you to distribute a subset of the full .Net package in certain supported scenarios. It still requires you to use an installer though - you can't just distribute individual assemblies. The benefit is a significant reduction in package size and deployment time.
No. In order for your pogram to run, the target machine must have the appropriate version of the .Net framework installed on it. You don't need to bundle the entire SDK with your application but you do need to include the appropriate .Net framework redistributable for your application.
I know of the Salamander tools... but haven't used them.
From their site: "Salamander .NET Linker, Native Compiler and Mini-Deployment Tool; Deploy .NET w/o Framework"
You can use tools like Xenocode to link the assemblies.
There's a free linker (from Microsoft, I think), but it's name escapes me.
This is not possible. You have to have proper .Net framework runtime in place on the target machine. What you have asked for is possible with 3rd party libraries/assemblies but not with .Net runtime.
Have you looked at ngen?

It would be possible to use reflection to identify the dependent assemblies and "link" them with your deployment. I've used a similar technique in Java land.
