I prepared a C# application that reads from registry and saves result in a simple notepad file. I tried to run it on another PC that doesn't have .net Framework. It gave initialization error because of not having .net Framework. The problem is that I can't install .net framework on that PC which has Win XP. Is there any way that I can run this application without having .net framework??
Please help as I need it urgently>>>....
Latest windows OS is normally packed with a default .Net Framework. Windows XP is packed with
XP
NET v1.0 Service pack 1
NET v2.0 -- Service packs 2 & 3
If it's not necessary for you to use latest version of .net Framework then you could change the target .Net Framework of your application[Go to Project Properties > Application > Target framework] to lowest version that default OS version has then you should be able to run your program without installing latest .net framework.
Pack .NET DLLs with the application.
In reference section set copy on build.
Right click on reference (e.g. System.Web) and press F4. Rest is pretty self-explainatory.

I have a clickonce application being tested on a virtual machine. This virtual machine is empty and my application requires .Net Framework 4.6.1 on the machine. Now, my application is able to install .Net 4.6.1 but I'm having a weird behavior after install. I'm receiving this message when the application is being open after the installation of .Net 4.6.1.
I added 4.6.1 on my prerequisite by following this guide. How to Create .Net Framework Prerequisites Entry in Microsoft Visual Studio 2015
Here's the message
When I try to run the setup again, the setup process goes through then it launches my application. It seems the setup cannot detect the framework installed right after it install it. Or something went wrong somewhere during the installation. Is there a way to handle this? Any suggestion will be appreciated. Thanks!
The error message says that your application requires CLR 4.0.xxxx. If you specify .NET 4.0 as requirement too ? Maybe you are trying to execute something developped with .NET 4.0 anyway. This could help you :
Backward compatibility and the .NET Framework 4.5 :
The .NET Framework 4.5 and its point releases are backward-compatible with apps that were built with earlier versions of the .NET Framework.In other words, apps and components built with previous versions will work without modification on the .NET Framework 4.5.However, by default, apps run on the version of the common language runtime for which they were developed, so you may have to provide a configuration file to enable your app to run on the .NET Framework 4.5.For more information, see the Version compatibility for apps section earlier in this article.

In Visual Studio 2015, in the New Project dialog box, above the "Blank App (Universal Windows)" template name there is a combo box where you can select the .NET Framework version.
By default .NET Framework version 4.5.2 is selected, and most screenshots in tutorials and guides show this version as selected. However, there is also .NET Framework 4.6 in the list that can be selected.
What would be the difference if I select .NET Framework 4.6? Can I use any new APIs and/or any C# language improvements in an Universal Windows App?
And will the app only run on Windows systems that have the .NET Framework 4.6 installed?
And will the app only run on Windows systems that have the .NET Framework 4.6 installed?
No, it runs on any machine or device that's capable of running Universal apps. The framework version number detail disappears once the Store packages your app, the framework methods you actually use are compiled into the package. Done by .NET Native, the ahead-of-time compiler for Universal apps. The package even runs on a device that doesn't have the .NET Framework installed at all, like a phone.
So the framework you select doesn't matter. Picking 4.5.1 or 4.5.2 or 4.6 doesn't give you extra capabilities, those runtime revisions had very few new api additions in the first place. But above all you build your project with reference assemblies that doesn't expose them. Note how you can pick 3.5 in the combobox and it makes no difference.
Review Project > Properties > Application tab. That's what really matters, you target a Universal version. Currently only build 10240 so nothing to fret about, yet. The framework version that targets is a subset of the .NET Framework you have on your machine, named .NETCore. It is a lot smaller than the full version.
Don't forget to test your Release build, very important to .NET Native.
I make a c# application project. this project run on my computer good, but in other computer says you must first install .NET Framework 4.0 to run this application.
How to embed .net framework 4.0 into c# project.
Thanks
You can't embed the framework into your application sine it needs to be installed on the client machine (not just xcopy'd like your app).
You'll need to create an installer which will take care of detecting and installing the required framework version before installing your application.
There is a tutorial here which shows how to create a setup project.
Once everything is set up, go to Project > [project name] Properties, click the Prerequisites... button and check .Net Framework 4. By default, the setup will download the Framework from Microsoft, so it will need an internet connection.
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.
If I create an application in c# 3.5, how could I make the exe compatible with all windows users?
I tried creating a couple of simple applications and send the exes from the bin folder and everyone has complained that they could not use them because they didn't have the update platform.
Any suggestions?
IIRC, C# 3.5 can generate code for .NET 2.0 or newer, by changing the project options.
But your users still will need the right version of .NET installed, and .NET 2.0 is not included in XP, not even with SP3.
If installing framework updates is too much to expect of your users, you will need to use native code instead of .NET.
You can change the target platform to a previous .NET framework version:
Check Menu| Project | Properties | Application and the setting Target framework, set it i.e. to .NET 2.0 if required - you will not be able to use new features then though - a better alternative would be updating those machines to add .NET 4.
It should be fine as long as you have it set to Any CPU and the users have the same .NET framework version installed.
