I am using Visual Studio 2010.
I made a C# project and it runs perfectly on my Computer.
Problem is this that when Application is run on another Computer, that ask for .Net Framework.
Everybody doesn't have administrator Access to install .Net Framework and also peoples don't want to install that.
What alternative i should follow to sort out this problem?
(Specifically for Windows 7).
Windows contains a version of .NET by default. Here's a listing of them.
XP
.NET v1.0 -- Service pack 1
.NET v2.0 -- Service packs 2 & 3
Vista
.NET v3.0 -- All service packs
Windows 7
.NET v3.5 -- All versions and service packs
Windows 8
.NET v4.0 + Metro UI available.
Windows 8.1
.Net v4.5 + Metro UI available.
Windows 10
.Net v4.6 + Metro UI + Universal Apps available.
Note:
All contains .NET v4.6 if Windows Update is enabled. (Not for all versions of windows)
Options of deployment:
There are several options of deployment.
Checking for .NET in installation. (Install systems like NSIS support this).
See this for more info.
If you want to deploy portable app, notify users to install the required .NET version. (easier)
Target .NET 2.0 and all users are able to run your app since I think nobody is using XP SP1. (easiest. I use this to deploy mine.)
EDIT
There needs some clarity with some other answers, so I'm quoting this Wikipedia note.
.NET Framework 1.0 is integral OS component of Windows XP Media Center edition or Tablet PC edition. Installation CDs for the Home editions and the Professional editions of Windows XP SP1, SP2 or SP3 comes with .NET Framework installation packages.
No way! CLR is absolutely needed for managed apps.
The only alternative is to not use a programming language that is based on the .net framework.
If you're writing a c# application, then the .net framework is required.
Perhaps you want to create a c++ application instead?
If you are targeting Windows 7 or later version of the OS, then just compile your program using C# 3.5. The version 3.5 of the framework is part of Windows 7.
I guess you were compiling C# 4.0 code.
Correct me if I am wrong but windows 7 comes with .Net framework installed. Windows Vista comes with installed .net framework and I believe this is valid for windows 7 as well.
And to answer your question - it is not possible to run the exe on a machine that does not have the framework as the program compiles to intermediate language that is only "understandable" by the Common language runtime(CLR)
Yes, there is Spoon (earlier XenoCode) that can wrap everything that your app needs and runs it in as a standalone.
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.

I have .net 4.7.1 installed. What if I build a .net application targeting that version of .net, and then package it as a Centennial app - What if someone with an older version of .net tries to install it (from the Windows Store)?
An official link confirming the answer would be nice, if possible.
EDIT
Since this seems to be unclear. The Windows Store presumably knows about your computer. The question is just what will it do about it. Will it prompt you to install the newer version like Clickonce can do, or just not let you install the app, or something else?
It depends. Keep in mind that Centennial is a bridge.
Centennial apps run on Windows 10 Anniversary edition (10.0; Build 14393) or later. On this Windows version the default installed .NET version is 4.6.2. Windows 10 Creators Update comes with .NET 4.7 by default.
So, if someone downloads your application on Windows 10 Anniversary edition and tries to run it, the following can happen:
.NET 4.6.2 is installed, your application doesn't use anything from .NET 4.7.1: your application works properly
.NET 4.6.2 is installed, your application is using .NET 4.7.1 specific features: your application doesn't work properly
.NET 4.7.1 is installed, your application doesn't use anything form .NET 4.7.1: your application works properly
.NET 4.7.1 is installed, your application is using .NET 4.7.1 specific features: your application works properly
You can apply the same logic for the later versions of Windows 10.
Another interesting option would be to package .NET 4.7.1 along with your application. If I understand it correctly, the Centennial apps have a virtual file system, which is basically merged with the real one. So, you should be able to install .NET 4.7.1 with your application and then package it together with your application. Then it will work on Windows 10 Anniversary edition as well on the later editions.
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 made a app that uses the watIn library, and target to .NET 3.5 (so it will work on XP to).
after i published the app on my PC, i installed it, and it worked well. but, when i tried it on different PC running XP, it didn't work. i made sure the PC I'm testing on is running .NET 3.5 or grater.
I'm running windows 7 and visual studio 2010.
the program work on Windows 7 (tried that on 2 PC's).
the program doesn't work on XP (tried that on 2 PC's).
On Xp i get this message:
Unable to install or run the application. The application requires that
assembly WindowsBase Version 3.0.0.0 be installed in the Global
Assembly Cache (GAC) first.
Please contact your administrator
my questions:
what should i do to make sure it work on XP?
if i start the development on .net 4, and then switch it to 3.5 and it still run, that mean i only used 3.5 code/features from the get go?
will visual studio give me compile Error if i run 4.0 code on app that i change his properties to target .net 3.5 in the middle of development?
is there a way to install the .net 3.5 framework with my app installer? (if it doesn't already got 1 on the PC)
(sorry for my English)
Make sure that the PC's running XP have .NET installed on them. Windows 7 will already come with the .NET Framework installed, but XP doesn't have the newer versions of the framework.
Also, if your project requires a specific version of the .NET framework, it's good to add it as a prerequisite in your setup installer.
Also, in your build, make sure you're targeting the proper framework.

I am creating a windows application for users with xp, vista or 7 PCs. I was wondering if WPF would work on all these computers, or should I play it safe and just use winforms?
Thanks!
Yes, they will run ok if the computer has the correct .net framework installed.
It would be a good idea to redistribute the framwork with your application. Here is a topic in msdn about how to do it MSDN
Windows Forms has been in .NET since .NET 1, with a few additions in .NET 2. WPF is available in .NET 3 – so, if someone has XP with .NET 2 installed, WPF won't work there.
Apart from that, you can of course install the appropriate .NET framework version on old machines as well. But the implication (WinForms works → WPF works) is wrong.
It will work on all of them, although you won't get the aero glass interface in XP. Obviously, you will need a reasonably up-to-date .NET framework runtime installed on the target machine.
WPF was added in .NET 3.0, so will run on any machine running 3.0 or a newer of the .NET Framework. However, the rendering technologies differ dramatically between WPF and WinForms, so you may need to take that into account. MSDN has a decent set of documents on WPF performance, some of which cover performance-related issues: http://msdn.microsoft.com/en-us/library/aa970683(v=VS.85).aspx.
We use WPF applictaions for XP, Vista and win7 customers and it works fine on platforms.
If you can get the right framework on the machine it will run. So far we are using Version 3.51 and no problems so far.
As other have mentioned, your dependency is on the ability to run the .net framework 3.0. .net 3.0 is supported on the following platforms according to the link below.
Software Requirements
To install .NET Framework 3.0, you
must have one of the following
operating systems installed on the
target computer:
Microsoft Windows XP Home or Microsoft Windows XP Home Professional, with Service Pack 2 or later.
Microsoft Windows Server 2003 family with Service Pack 1 or later.Service Pack 1 or later.

What are the requirements for running .net framework targeted application on Windows CE 5?
If I try to start an application that I developed for Windows Mobile 6, I will get the following error.
Cannot find 'Projectname' (or one of
its components) Make sure the path and
filename are correct and that all the
required libraries are available
My app is a simple hello world app. What could cause that such error message?
Is there a way to dertimine which .net compact framework version is running on my system?
You can run cgacutil, which is in the Windows folder. It should give you a version number of the compact framework installed onto the device. It's likely you dont have the correct compact framework installed.
If you dont have cgacutil, its likely that compact framework isnt installed to the device at all. In this case download the latest version of the framework (currently 3.5, available here). The install may take around 7MB of space from your main memory. If storage space is tight, it can be installed to external memory, with some potential consequences as discussed here
The problem is caused by what you're wondering... Which version of compact framework is installed in your system and, most of all, if there is a version of compact framework installed.
I suggest you to download the version corresponding to your developing environment and install it in your device.
By default, Windows Mobile 5 comes with .NET Compact Framework 1.0 SP3 pre-installed.
An application developed for Windows Mobile 6 is at least going to use .NET Compact Framework 2.0 SP2, therefore make sure that it is installed on the Windows Mobile 5 device.
You can download it here, but generally it is a good practice to install the latest version available, as long as it is supported by the device.
