Error in running c# windows application - c#

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.

C# application host version detection when no .NET runtime is installed

I have an application that relies on .NET 6 runtime. If I don't have any .NET runtimes installed on my machine, not only the one my application needs but also without other versions of .net runtime, I could see some messages prompted when execute it.
Does anyone have any insight about how the detection work or who gives the prompted information? Is it done by the OS?
Thanks!
Windows 10 and 11 comes pre-installed with .NET Framework.
A .NET 6 application can be released as a self-contained application that includes the required runtimes to run (if it is not on the machine) as suggested here; https://stackoverflow.com/a/72630528/1165173

.NET Desktop Runtime is required before installation

I've developed an application in .NET 5.0, also, I've a Setup Project to install this application in my clients.
My steps are:
1.- Publish the .NET 5.0 Application.
2.- Compile the Setup project.
3.- Install the setup.exe generated in "2" in the client.
But when I try to install the program in my client, windows says "This installation requires the 5.0.0(x64) version of .NET Desktop Runtime... So I've to download and install the SDK in every client.
My question is: There is some way to avoid this SDK installation? Can I embeed the .NET Desktop Runtime in the .NET 5.0 App or in the Setup Project?
Thanks in advance.
See .NET application publishing overview, specifically publishing a self-contained application. That way all necessary framework files will be included in your application, and you will not the framework to be installed. This will increase the disk requirement a bit if .Net 5 is already installed, since some files will be duplicated.
The alternative is to bundle the the .Net framework installer in your installation script. This will cause the setup-file to be quite a bit larger, unless the script downloads the framework on demand. But it may save some disk space in case there are multiple applications that use .Net 5.

Unable to launch a wpf application on windows XP machine

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

.Net CF Initialization Error

I have a windows CE app that built it with MS VS 2008 smart device .NET 3.5.
after transmit this app to hand held i see below error.

you can see the compelete error in below picture :
can i improve my device .Net version without change windows CE ?
or i have to recreate this app with .NET 2.0 ?
Please check, which CF version is installed on the device, run cgacutil.exe in windows dir.
The device (an Intermec CN4, according to the title in the screenshot) comes with Windows Mobile 6.1. But I am not sure, if it comes with CF2 or CF3 pre-installed.
Bellow Location has two Folders
C:\Program Files (x86)\Microsoft.NET\SDK\CompactFramework\
v2.0
v3.5
Check All Reference's paths in Solution Explorer. same version should be selected for all reference's from the correct folder as the version you selected on the time of Project creation.
As Windows CE forms are available in both Versions.
in v2.0 as Microsoft.WindowsCE.Forms
in v3.5 as Microsoft.Windowsce.Forms
If Started the Project with .Net v3.5 and added Reference of Windows ce forms from v2.0 folder. the OS will ask for .NET CF Initialization .

Windows installer 3.1

Visual Studio 2005
I have developed an application using C#. I have created an setup application, and included the .NET Framework 2.0 on the CD.
I am not using ClickOnce.
However, one of our clients is complaining that they cannot install as it's asking
for Windows Installer 3.1. However, I didn't exclude that from the setup project.
To do a complete test I decided to install some VMware that didn't have the .NET framework or Windows Installer 3.1 (just a skeleton Windows XP). The application installed OK.
What is the Windows Installer 3.1? And why do I need it?
Windows installer is the software that is able to run MSI files. It comes (in some version) with Windows (starting in Windows 2000 SP4). In each MSI file, the minimum installer version is defined; installer will complain if the MSI is "too new". The Windows SDK has a table showing what installer versions where included in what Windows releases.
You can get the 3.1 redistributable from Microsoft.
You need it to install .NET framework 2.0.
Please check this download link.
Its System Requirements says:
System Requirements
- Required Software:
o Windows Installer 3.0 (except for Windows 98/ME, which require Windows Installer 2.0 or later). Windows Installer 3.1 or later is recommended.
o IE 5.01 or later: You must also be running Microsoft Internet Explorer 5.01 or later for all installations of the .NET Framework.
EDIT : You can make sure in your setup project that all the prerequisites for your project exists in your Setup Package. You can find a step-by-step how-to in this CodeProject article..
