c# app doesn't work on XP - c#

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.

Application in c# without dot net framework [duplicate]

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.

Centennial app targeting .net higher than installed - What will happen?

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.

WPF Program - program is not valid win32

I have create a Small WPF C# Program with VS2012. it is run successful in Win 7 and Win 8 , 32Bit and 64bit
but it have trouble with windows XP and after runnig exe file This message is displayed:
program is not valid win32
What is the solution?
you should reduce the target framework of your Project. VS2012 runs with .NET 4.5 as default, Windows XP does not support anything higher than .NET 4.0.
You can go to your Project Properties and select at the tab Application the Target framework.
Make sure you have installed .Net framework in target machine. Windows XP does not support .NET 4.0 and higher
Try the workaround mentioned in the following link.
http://blogs.msdn.com/b/vsnetsetup/archive/2012/10/16/setup-exe-is-not-a-valid-win32-application.aspx
But still you need to open up to us to give accurate solution.
Additional to this, just make sure the platform target of the program is not x64 if you are running it in a 32 bit machine. .Net framework 4 should work in windows XP machine.

Windows XP compatibility

I am working on a project that targets Windows XP platform. I have been developing it on a Windows XP virtual Machine with Visual Studio 2008 (with .NET 3.5) to make sure that it is going to work for my client. But this method became annoying (turning on, turning off, minimizing, restoring the virtual machine window, the lower performance). On my native machine, I am using Visual Studio 2012 Ultimate on Windows 7.
If I am going to import the project from that machine to my native one and continue developing it, how can I be sure that it is going to work on Windows XP?
My application is written in C# for .NET Framework 3.5.
Make sure you target .Net Framework 3.5 in Visual Studio 2012.
How to: Target a Version of the .NET Framework
Rebuild the application and test it in the Virtual XP machine. Windows XP is supporting .Net Framework 3.5 so there should be no problems.
Microsoft .NET Framework 3.5
But do tell your client that the Microsoft support for Windows XP is going to end soon so they should start planning an upgrade.

C# project created install package on Win7 64 bit machine will not install on Win XP

I am hoping you could resolve this issue. I have made a small application in C# and I publish it with the prereqs of .Net 4.5 and SQL Server Compact 4.0. One of the users of the app is running under an old core which has win XP on it. It appears that .net4.5 will not install on XP for some reason. So I tried to publish a separate configuration with all the prereqs turned off and that did not install either. I am looking for advice how to configure this installation version so this person can run it. What’s the latest version of .NET that can be installed by an XP user?
Any help you can provide will be much appreciated.
Do you use .NET 4.5 in your application? If so, you will need those pre-requisites turned on...if not, why add the pre-requisite??
.NET 3.5 SP1 can be installed on XP (a quick google search would have provided this)
For the not being able to install, as you haven't provided any logs etc then we cannot help you much.
