can .net framework 4 works on top of windows xp?
We are considering various framework and languages options to develop our database driven Desktop Application for our target market which, unfortunately, abundantly uses Windows XP in their systems. Can anyone please confirm that if we develop a desktop application in C#/.NET framework 4.0, will that application be able to run on Windows XP? I understand that to run .net developed applications, we need to have .net framework installed in end-users' system so my 2nd question is: can we install .net Framework on Windows XP (with no service pack installed on that)?
Waiting to be enlightened by your expert answers.
It's not clear why you think you've got two questions here - they're both basically "does .NET 4 run on Windows XP" which is easily answered by the system requirements page.
That shows that .NET 4 works on XP Professional, XP Home Edition and XP Professional x64 edition. It does not work (or at least isn't supported) on Media Center, Tablet PC or Starter editions.
I would expect it to be an optional install via Windows Update, so you may find that some of your customers already have it installed, but plenty of others don't.

I want to make an Windows Desktop Application for Windows 7 and above.
Can someone tell me how can I start? I have tried searching on Google for developing apps for Windows; all I’ve found so far is UWP (Universal Windows Platform) which I believe works for Windows 10 and above. I have even checked the Microsoft docs and all they are telling is about Windows 10 apps, not a word about versions below it.
Can someone tell me if I make an app for Windows 10 will it work with earlier versions too? As the main requirement is developing for Windows 7.
I have been doing coding for 3-4 years so I know coding. I just want to start from right path. Please guide me.
Jason is right to a point, UWP is the modern way, but I would actually recommend WPF which was designed to replace Windows Forms.
It uses modern techniques and methods with C# like Caml for the UI layout, MVVM, View Model bindings etc, and it's all transferable skills into UWP and Xamarin mobile apps. As an aside Xamarin Forms are looking to build out WPF apps in future releases for true cross platform apps so it's a good framework to learn for Windows desktop.
Start here - https://learn.microsoft.com/en-us/dotnet/framework/wpf/getting-started/walkthrough-my-first-wpf-desktop-application
You are right that UWP is for Windows 10 and above, so I would stay away from that in your case.
What you should start with is a simple basic Windows Form development in C#.
Download and install Visual Studio 2017 Community Edition from here: https://www.visualstudio.com/downloads/
Then I suggest looking for tutorials online for Windows Form apps in C# which can guide you through it.
Here are a couple that could help.

There are more but they are for older VS Studio versions, but the principals are the same even if the UI is a bit different.
The DotNet Framework takes away a bit the dependency upon a specific windows version. As longer as your windows version can run the DotNet Framework version you are targetting (compiling for) then it will work in most cases.
Best to first find out which DotNet framework version is installed on your target PC and then build for that, or upgrade it.
It might look a bit different on different windows version, so if you are compiling on a different platform to what you are running on then it is best to make sure that you do testing on your target platform.
This shows how to change your target DotNet version in Visual Studio: https://www.youtube.com/watch?v=E36kiGWfGCQ

I'm looking into various options for using DirectX in C#; ideally I want to use whatever technology is preferred by Microsoft.
Non-Microsoft Technologies:
SharpDX
Slim DX
Direct2D Manager Wrapper
Microsoft Technologies:
WPF
DirectX 9.0 for managed code (deprecated)
XNA Framework (deprecated)
Rationale behind the technology I want to use:
I want a code-first framework (as opposed to writing XAML in WPF)
I want (ideally) a Microsoft supported framework that isn't deprecated
I want to build applications that don't over-rely on 3rd party dependencies (i.e. If I was to build an application with WPF, the framework will likely already be installed on the users machine as part of the .NET framework)
Questions:
What is Microsoft's prefered method for writing DirectX exabled applications (aside from WPF)?
What dangers are there in using deprecated technologies (MDX, XNA)?
What is the most popular non-Microsoft DirectX technology that can be used from C#?
The DirectX technology is central to modern Windows presentation and game graphics, so there's lots of different avenues to it. Your question doesn't really state what kind of application you are building or what platform you are trying to target.
Managed DirectX 1.1 has a long list of issues at this point: it doesn't support .NET 4.x which means VS 2010 or later C# projects by default can't use it. It uses legacy D3DX9 and legacy DirectSetup deployment. It does not support 64-bit native apps. It only supports Direct3D 9 and not Direct3D 10.x or 11.x. It exposes a bunch of legacy stuff like DirectPlay and DirectSound. It hasn't been updated since ~2006 and finding samples for it is a challenge. It does not support Windows Store apps, Windows phone, Xbox 360, or Xbox One.
SlimDX is a good choice for someone who has an existing Managed DirectX 1.1 application who wants to move to something a bit better supported. It is compatible with x64 native apps and .NET 4.0. The project has indeed stalled in terms of progression, but it's open source so you can always work with it yourself.
XNA Game Studio 4 supports .NET 4.0 and can target Xbox 360, Windows phone 7, Windows phone 8 (in appcompat), and Windows 32-bit apps. It does not support x64 native apps, and the content pipeline is only compatible with VS 2010. It uses legacy D3DX9 so it depends on the deprecated DirectSetup deployment. It exposes Direct3D 9 and not Direcxt3D 10.x or 11.x. It does not support Windows Store apps or Xbox One. It's specific to writing games.
Windows Presentation Foundation has Direct3D9/Direct3D9Ex interop, but not Direct3D 10.x or Direct3D 11.x. This is a useful technology for Win32 desktop apps, but is not supported for Windows Store apps, Windows phone, or Xbox One. See MSDN. It's not particularly suited to making games, but many game developers have used it for their tools pipeline. The lack of DirectX 10.x/11.x support is challenging, but you could make it work with DXGI Shared Surfaces with Direct3D9Ex.
Note that there is a GitHub project WPF DX11 interop that can be helpful here.
SharpDX is a popular choice for a C# mapping of the modern DirectX APIs. It also supports Windows Store and Windows Phone apps, and is an active project.
BTW, If you are just looking for a direct way to use Direct2D from C# you may want to look at Win2D.

Running .net based application without .NET Framework

I created a windows application using c#.net, and i converted it into .exe
can i run this application on another system without installing .net framework?
please clear my doubt.
Thanks
C# apllications are not handled by the operating System. Its CLR(inside framework) (Common Language Runtime) who takes care about running the C# apps and also about all memory management, resource allocation, de-allocation etc. It creates a virtual layer over the OS while running the application. So you need the .NET-framework!
Its not about C#. Its about weather 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 that , 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.

I am .Net Developer who started using Mac OS. The only thing that I miss on this system is "VISUAL STUDIO".
I don't wanna use two systems, What do you think in order to develop .Net application
Do you think that I should install Virtual box and use Visual Studio
http://zeus.cs.pacificu.edu/chadd/InstallVisualStudioOnYourMac.html
Or Just use Mono Develop? Is Mono Powerful enough to develop application that is compatible with Windows and run on Mac ?
I am purely .NET developer, but lately also developing iOS applications with using Xamarin (new name for mono libraries) and Xamarin studio (rebranded Monodevelop).
So, if I understand you correctly and you still want to develop .NET applications but just working and "live" in MacOS, the I would say that you have no chances.
Even if consider, that you can have an ability to write code (and even to have some .NET libraries to use even there) in Monodevelop, that's just incomparable, how VisualStudio is amazingly convenient for developer (especially, for native .NET one) and how many plugins it has.
So, from my point of view, there is even no talk: you must use VisualStudio in any case! Even if you use it in Remote Desktop.
UPD: Time flows and things change. Currently .NET is really spread even to Mac. Visual Studio Code been released for coding and Xamarin became available for Free since the answer was asked.
However, one thing will probably never come true: I am doubting Visual Studio will ever be able to migrate from Windows. It will be rather some new product or extending of Visual Studio Code.
Of course you can use Mono to develop an application that is compatible with Windows, although Mono is nowhere near as robust/easy to use/ feature filled as VS.
That said depending on the type of application you plan to develop, it may make sense to install windows in a virtual box so that your application can actually run on your computer.
For example, if you are trying to make a Windows Forms application, your app ( which can be completely developed in Mono, but will not run on the native OS X. This will most likely make debugging a nightmare.
If you're on the fence it might make sense for you to download a 90 day free trial of a windows OS from microsoft, run that in a virtual box and try out visual studio.

I have a C# application which needs to run on a client's machine but the client does not want to have to install the .NET framework. He wants my application to run 'as-is' from a CD or a PenDrive.
How do I make this happen?
You need the appropriate version of the .NET framework installed in order to run .NET applications. That's pretty much a requirement.
It's just like trying to run a Java application without the JRE installed, or a PHP application without PHP.
Sorry but this is not possible. You need the .NET framework on the machine with the C# code on as the C# code relies on .NET to actually DO anything.
