I have created a WPF application with target Framework 4.5 on Windows 8 machine. The application has reference to two c# dlls with same same target framework. I have used Linq to entities to connect to a MS Sql server database in my application.
Now, When I tried to run the same application by running the exe file located in Debug folder in a Windows XP machine, it gives following error message
D:\Main\TPMS\Debug\TPMS.exe is not a valid win32 application.
What is the issue here?
.NET Framework 4.5 is not supported on windows XP. Try targeting .NET Framework 4.0. Another option is to use Mono but since it lacks support of WPF then you should stick to .NET Framework 4.0
The .NET Framework 4.5 and later versions are not supported on Windows XP
NET Framework 4.5 and Windows XP

The server runs windows server 2008 R2 that has .NET 4.0 framework as its highest supported version. I did see people commented that .NET core supports frameworks comes later than 4.5.
I think you can run it on Windows 2008 R2 if you install SP1 and the suitable Core Framework.
Supported Windows Version:
Windows 7 SP1
Windows 8.1
Windows 10
Windows Server 2008 R2 SP1 (Full Server or Server Core)
Windows Server 2012 SP1 (Full Server or Server Core)
Windows Server 2012 R2 SP1 (Full Server or Server Core)
Windows Server 2016 (Full Server, Server Core or Nano Server)
and your System should be up to date:
For Windows 7 and Windows Server 2008 machines only:
Make sure that your Windows installation is up-to-date and includes hotfix KB2533623 installed through Windows Update.
You can find more information here:
https://learn.microsoft.com/en-us/dotnet/core/windows-prerequisites
or you can read the release information form the differnt core versions on github.
According to .NET Core documentation here, you can target Windows Server 2008 R2 SP1 on .NET Core.
You can also upgrade to .NET Framework 4.5.2 on Windows Server 2008, refer this link.
If however, you cannot upgrade to .NET Framework 4.5 and above, I think you are out of luck. Refer .NET Standard
.NET Core doesn't know about, or really interact with, .NET Framework. Conversely, .NET Framework doesn't really know about, or interact with, .NET Core. So this question is sort of like "can I put Photoshop on a machine which currently has mspaint, but not paint.net?".
.NET Core applications can either be published and run in a mode where they depend on a shared framework having been installed, which makes each individual application smaller but has a prerequisite. Or, you can publish an application as everything it needs to run on some other machine as a "self-contained" or "standalone" application, which makes the application easier to run on an arbitrary machine (of the correct OS family) but at the expense of it being larger.
If you can't change the dependencies of the target machine at all, you want to go the self-contained route. If .NET Framework 4.0 is the newest available (even though it is out of support) because of an admin being concerned about upgrading shared dependencies then maybe you can get the .NET Core runtime installed, since it won't interact with .NET Framework, and then you can stick with the smaller footprint deployment.
For an explanation of self-contained vs framework-dependent (and how to do it), see

i am developing WPF application in visual studio and using .NET 3.5.
does the application fits Windows7 and Windows8 OS with no .NET framework additional installation?
do i need to add .NET 3.5 installation to setup project?
In Windows 7 .NET framework 3.5 is part of the operating system so all machines should have it.
In Windows 8 or windows 8.1 .NET framework 3.5 is NOT automatically installed (though all machines that are upgraded from win 7 -> win 8 should have it).
To run apps that require the .NET Framework 3.5 on Windows 8 or later, you must enable version 3.5 on your computer. There are two ways you can do this: by installing or running an app that requires the .NET Framework 3.5 (that is, by installing the .NET Framework 3.5 on demand), or by enabling the .NET Framework 3.5 in Control Panel. Both options require an Internet connection.
If an app requires the .NET Framework 3.5, but doesn't find that version enabled on your computer, it displays a message box, either during installation, or when you run the app for the first time. In the message box, choose Install this feature to enable the .NET Framework 3.5.
The above require an internet connection. If this is not possible you will have to include the .exe files of .NET 3.5 in your distribution
however as MSDN states:
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
So build your project for 3.5 and just deploy it to windows 8 machines. It should run, but its not the "best" environment for the app. The "best" would be to have .NET 3.5 installed.
I wrote a c# windows application and I want to run it on other computer without any installation.
I setup the netCFSetup v35 but when I run my application this error was apeare :
the application failed to init....
can anyone help me please?...
I think you are installing wrong framework for you application.
Since its a windows application i suggest your install .Net Framework of Desktop. The one you are installing is of Compact Framework (CF in filename netCFSetup v35) which was used for Windows Mobile 6.5 or earlier.
If you created your app in .Net 3.5 version. install this version

To know in which version of .Net Framework your app is written in, go to properties section of project. There you will get your version number.
I am facing a lot of trouble while deploying a windows form application on a CD. I have made the application in .NET framework 2.0 and I want to include the setup for the framwork with the installation disk. The application is to run on WindowsXP(damn, user requirement). I tried deploying it with 1 click deployment in VS2010 but the setup does not run on winXP.(Error-.NET framework 4.0 required to run the application). Is there any way of deploying the app which can run on winXP(.NET 2.0), win7(.NET 4.0)-32 bit as well as 64 bit environment.
A 32 bit app will run on 32 or 64 bit operating systems.
A .NET 2.0 application will run on .NET 2.0 or .NET 4.0.
Sounds like your installer is the only dependency on .NET 4. Check the publishing prerequisites you have set on your project.
Visual Studio 2010 doesn't provide a .Net 2.0 pre-requisite for deployment projects. A MSDN support rep explained (?) this in this question:
In VS 2010, it doesn’t support you to set .NET Framework 2.0 as
prerequisite. You can set .NET 3.5 SP1 client profile instead.
Although your application is still build target to .NET 2.0, .NET 3.5
client profile is a light weight .NET framework run time which
supports to run .NET 2.0 based application. So Microsoft removes .NET
2.0 from the prerequisite list.
There's a solution though in that thread:
If you take the .NET 2.0 package from the VS2008 bootstrapper packages
folder and copy it to the corresponding location for VS2010, it works
fine. I tested it in a virtual machine running Windows XP and no .NET.
On Vista or Windows 7, the VS2008 packages are here:
c:\Program Files\Microsoft
SDKs\Windows\v6.0A\Bootstrapper\Packages\DotNetFX (this is .NET 2.0)
On Vista or Windows 7, the VS2010 packages are here:
c:\Program Files\Microsoft SDKs\Windows\v7.0A\BootStrapper\Packages
See the other posts in the thread for more detail.
I'm writing a C# app (in VS 2008). If I target the .Net 3.5 framework, will it run on Windows XP and above? Will XP users potentially have to download a .Net upgrade?
UPDATE
If the app is intended for business / corporate environments do you think it's pretty safe to target 3.5 rather than 2.0?
Only Windows 7 and newer will come with .NET 3.5 (SP1) pre-installed; Windows XP and Vista users, while able to run apps built on .NET 3.5, have to download and install it first in order to use your app.
I think the latest service packs of XP and Vista include .NET 3.5, though.
If the app is intended for business / corporate environments do you think it's pretty safe to target 3.5 rather than 2.0?
Not if the client machines are not able to upgrade or install the 3.5 Framework.
It's not safe to assume they already have the framework. It is realistic, however, to have them install the framework. They probably have it, and if they don't then they should get it if you're writing an app in 3.5.
