I'm trying to compile my program in Visual C#. However, the machine I need it to run on (well, I need it to be able to run on any Windows Machine, at least Windows XP) does not have the .NET DLLs installed. I'm new to this, so how can I compile my Visual C# program with the runtime DLLs so that it will run on other machines?
If you use Click-Once deployment, you can set a setting in the installer that the installer should install the .NET framework before running. If that's not an option (such as target machine has slow/no internet connection) you can install the redistributable version of .NET
There is no way. You need .NET runtime installed prior running any .NET application.
You can't. .Net programs can only run if the .Net framework / CLR is installed on the target machine. There is no pure XCOPY deployment story for this scenario.

I was able to run console application targeted to .net 4.7.2 on machine where .net 4.7.0 is installed.
Can I safely run .net 4.7.2 targeted application on machine which has .net 4.7.0 installed?
No there is no guarantee that this will be "safe". Your program might fail at runtime. One way to ensure that you can run your app, is to create an installer for your console application. This way you can execute this installer and it will install the necessary packages along with your application, and the target machine does not need to have Visual studio installed altogether.
I have created Sales Management System using C# and MS SQL Server 2012. This is working fine. All I want to know in how can I create an exe so that this can be installed in another machine without any .NET Framework.
e.g. it should say like SalesManagementSystem.exe, and I should be able to install it in any machine.
Just download the Setup project templates and create an installer:
https://marketplace.visualstudio.com/items?itemName=VisualStudioProductTeam.MicrosoftVisualStudio2015InstallerProjects
See my extensive guide here on how to make an Installer (one that upgrades itself as well):
Install to same path when upgrading application
A .Net application will never run without the corresponding framework installed. But depending on the target OS the framework is already installed. Please check the release history at wikipeda. There you can see which .Net version is already installed in which windows version.
If you want to deploy a single executable you have to embed all your depending assemblies into your executable as a resource (plenty of questions and answers are already at SO) and load them by overwriting the AssemblyResolve event.
If you want to create a windows installer take a look at WiX.
You cannot just skip the .NET Framework on the target machine - it is needed to run your program. The exe file, produced by the C# compiler contains MSIL, which is understood by .NET Framework, as opposed by the destination OS - be it Windows or any other.
Having that said, your best bet is to write an installer for your app and
distribute the .NET Framework distribute the .NET Framework along with it. When launched, the installer might check what is the installed version of the .NET framework on the target machine (if any) and respond appropriately by installing whatever it is needed for your application.
You can use WiX to author an installers.
I wrote windows application with C# and SQLite. When Microsoft Visual C++ 2010 Redistributable Package x86 was installed on a PC application runs correctly but if Microsoft Visual C++ 2010 Redistributable Package x86 not install, application doesn't run. Why?
Is SQLite depend on Microsoft Visual C++ 2010 Redistributable Package x86 ?
The version of SQLite is compiled by VS2010, and it depends on the C runtime libaries, thus it needs Visual C++ 2010 Redistributable Package x86.
Yes. SQLite is probably written in C++. It's compiled with /MD option which means it needs the msvcrt#.dlls at runtime. The Restributable Package installs this without which it cannot run
Because SQLite obviously developed the SQLite.Interop.dll in C++, and because they say so:
(11) Why do I get a DllNotFoundException (for "sqlite3.dll" or "SQLite.Interop.dll") when trying to run my application?
Either the named dynamic link library (DLL) cannot be located or it cannot be loaded due to missing dependencies. Make sure the named dynamic link library is located in the application directory or a directory along the system PATH and try again. Also, be sure the necessary Visual C++ runtime redistributable has been installed unless you are using a dynamic link library that was built statically linked to it.
Emphasis mine on that last part. You need the static binaries from the system.data.sqlite download page in order to NOT need the C++ runtime. On that same page, where the binaries are provided, those that do require it will tell you it is - for example, the Visual C++ 2010 SP1 runtime for x64 is required for 4.0, and Update 4 of that is needed for .NET 4.5, according to the page. I've used the 2015 version, Update 3, with the .NET 4.0 versions with no issues.
Note - you might not be aware, but if you try hosting an application that uses the SQLite DLLs on a file share and connect to that application across the network from a workstation, that workstation will still need the C++ runtime because it is running the application in its memory.
Reference: http://system.data.sqlite.org/index.html/doc/trunk/www/faq.wiki#q11
Link to Microsoft Visual C++ 2015 Redistributable Update 3, which I know works with the 64-bit, .NET 4.0 versions of the SQLite binaries:
https://www.microsoft.com/en-us/download/details.aspx?id=53840
SQLite depends on the Visual C++ runtime, but you don't need to install it on the client machine. The system.data.sqlite download page contains several "static" packages that already contain the runtime.
All the "static" packages contain either native or mixed-mode assembly binaries linked statically to the appropriate version of the Visual C++ runtime. Typically, these packages are used in cases where customer machines may not have the necessary version of the Visual C++ runtime installed and it cannot be installed due to limited privileges.
For example, on my machine I am running Windows 8.1 x64 so I went under Precompiled Statically-Linked Binaries for 64-bit Windows (.NET Framework 4.0) and downloaded sqlite-netFx40-static-binary-x64-2010-1.0.90.0.zip.
This binary package contains all the binaries for the x64 version of the System.Data.SQLite 1.0.90.0 (3.8.2) package. The Visual C++ 2010 SP1 runtime for x64 is statically linked. The .NET Framework 4.0 is required.
I then unzipped the package and ran test.exe to make sure everything works. Zero installation required.
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.
My programming language is C# .Net 3.5 and I may have to install my applications in very old client systems (windows XP-SP1 and above) and may be that those systems do not contain any version of .Net (or even Windows-Installer-3.1) in them.
I have worked on VS-2008 deployment projects on and off since some time and I have some working knowledge of it.
I want to write a deployment project in VS-2008 but I have 2 questions :
Can a VS-2008 deployment project containing pre-requisites run on a system without any version of .Net (or even Windows-Installer-3.1) pre-installed in the system ?
How to create a boot-strapper installer to run in systems without .net pre-installed in them (boot strapper will install all pre-requisites including .net and other 3rd party run times) ?

Yes, the EXE bootstrapper which handles prerequisites doesn't have any dependencies. So you can safely add Windows Installer and .NET Framework as prerequisites in your setup project.

Here is an article which may help: http://setupanddeployment.com/uncategorized/custom-prerequisite-visual-studio-setup-file/
You can use Salamander .net linker. I don't exactly understand what it does but what I know is that I was able to pack the necessary reference and the program into 1 folder. When I move the folder to a computer without .net framework installed, it was able to run.
The demo version of the program will give u nag screens every time u run the packed program.
The side effect of doing it this way is my program file size increased from few KB to 40MB.

You need to have .Net version installed on the client system.
Else it wont works.
Because even to start your application your application will search for CLR 2008 version.
You can do one thing. If you dont want to install .Net Framework, please develop your application in lower version of .Net framework.(May be .Net 2.0 will work without any requirement since it is XP SP1)
No, because there are not just DLLs, there is common language runtime needed to execute your program. Read the great book by Richter to better understand what happens when you create a program using .net libraries and its lifecycle.
By the way, i'm not quite sure, there must be some older version of .net installed with SP1. So may be you consider changing your application to use .NET 2?
UPDATE
May be you want to add .NET to your setup as prerequisite? You can add them without creating bootstrapper packages. See the article: http://www.codeproject.com/Articles/35976/Add-Prerequisites-of-NET-Framework-in-Visual-Studi
