I make a c# application project. this project run on my computer good, but in other computer says you must first install .NET Framework 4.0 to run this application.
How to embed .net framework 4.0 into c# project.
Thanks
You can't embed the framework into your application sine it needs to be installed on the client machine (not just xcopy'd like your app).
You'll need to create an installer which will take care of detecting and installing the required framework version before installing your application.
There is a tutorial here which shows how to create a setup project.
Once everything is set up, go to Project > [project name] Properties, click the Prerequisites... button and check .Net Framework 4. By default, the setup will download the Framework from Microsoft, so it will need an internet connection.

I am making a project in Visual studio in C# and when I tried running the built and published project on my friend's computer it gives an error that a certain version of .Net is not installed. I know that you can make projects in C++ and that doesn't require .Net, but I don't want to learn a new language and I mostly get youtube help from people that code in C#. anyone that knows Visual studio, can you tell me if there is a format I can make the project in? for example, Console application, NUnit test project, etc. thx
You can publish an application with self-contained enabled. This will build an application that includes all the dotnet framework files needed to run the application.
This does make the application bigger, even the most basic dotnet6 console app on my machines is ~10mb and when it's framework dependent it's 160kb
the settings used in the UI:
You can do this in console with:
dotnet publish -r win-x86 -c Release --self-contained true -p:PublishTrimmed=true -p:PublishSingleFile=true
Some good docs on trimming and publishing:

You need to download the framework that your project is using to be developed in and install it on your friends PC. This is normal and with more advanced software engineering you would build an installer that could install it as part of your applications installation.
For now, check what version of the .NET framework your application is build in. You can do this by going to your Solution Explorer window, right clicking on your solution and selecting properties. It will open a new tab menu on the left of your screen and you want to select the Application. In there you will see a drop down menu labelled "Target framework" which shows what framework your project is using, for example ".NET 5.0"
Once you know which framework your project uses, you can go to https://dotnet.microsoft.com/ to download the installer for that framework on your friends machine. Run the installer and once it has the relevant framework, it should run your application fine.
Additionally to what Istalri Skolir has said, you could also try to optimize for a certain Windows version, by using a preinstalled .NET version.
Here's a list of .NET Frameworks included in specific OS versions.
For example:
Windows 10 May 2019 Update (all editions) includes the .NET Framework
4.8 as an OS component, and it is installed by default
You will need to define the .NET Framework version in the project settings.
I prepared a C# application that reads from registry and saves result in a simple notepad file. I tried to run it on another PC that doesn't have .net Framework. It gave initialization error because of not having .net Framework. The problem is that I can't install .net framework on that PC which has Win XP. Is there any way that I can run this application without having .net framework??
Please help as I need it urgently>>>....
Latest windows OS is normally packed with a default .Net Framework. Windows XP is packed with
XP
NET v1.0 Service pack 1
NET v2.0 -- Service packs 2 & 3
If it's not necessary for you to use latest version of .net Framework then you could change the target .Net Framework of your application[Go to Project Properties > Application > Target framework] to lowest version that default OS version has then you should be able to run your program without installing latest .net framework.
Pack .NET DLLs with the application.
In reference section set copy on build.
Right click on reference (e.g. System.Web) and press F4. Rest is pretty self-explainatory.
i am working on a dotnet C# web application which was initially created with VS 2003. My goal is to upgrade this application to Dotnet 4.0 without changing any functionaltiy. The solution has 9 projects (1 web + 8 Library projects). The Web project refers the 8 libraries in DLLs. To start off, I created a New project in VS2010 and added the all the Project files from the existing source code. Every time i add a project file to my solution, i was prompted with the Converison wizard and i completed the conversion wizard succesfully and now the solution works fine. After the conversion, i noticed that Except the "Web" project, other projects are converted to Dotnet 2.0 but not 4.0. My application runs without error if i run it locally using VS2010. My questions are
Why the Class libaray project did not upgrade to 4.0? Currently the
Web project is shows up as Dotnet 4.0 and Libaray projects shows up
as Dotnet 2.0.
Can i deploy the application to IIS 7.0 with the
Dotnet runtime of 4.0? Will the Dlls created in version 2.0 work if my application
uses Dotnet 4.0 runtime version?
Please help...
If your'e migrating now, why not move directly to Visual Studio 2012, instead of 2010?
Anyway, what you can do is open the project properties in each of your projects, and change the target framework to the .NET framework 4.0.
Then if you get any compilation error you can probably easily solve it individually. This should be relatively easy if your projects are not too big.
As for your specific questions:
The automatic conversion would only change the format of the solution/projects to be compatible with the new version Visual Studio. It shouldn't change the target framework but you can change that yourself.
Yes, assemblies targeting .NET 2.0 can be loaded and used from assemblies targeting .NET 4.0.
1) Upgrading the solution/projects file only upgrades it's format so you can open it in VS 2010. It will usually leave the targeted .NET setting at the previous value. These are two seperate things. The wonderful thing about VS 2010 is it let's you target whatever version of .NET you desire, so no longer do you need multiple version of VS installed to support differnt .NET versions. It didn't change the targetted .NET version because it leaves it up to you. You can change it under the project settings and recompile your library projects to regenerate the DLLs
2) You will need an application pool for .NET 4. .NET is backwards compatible in that a .NET 2.0 app can run on a machine with .net 4 installed. However, the application pool for 2.0 applications must be separate from 4.0 apps. So it's just a matter of putting the app under the right app pool.
I have create a application that uses the .Net framework 4. I have created a installer with the setup wizard, but when i run the installer it wants to install .Net 4 client . If i try to start the application it says this application needs .Net Framework, version 4.
Anyone knows how to fix this.
no magical way around this.
download the .net framework http://www.microsoft.com/download/en/details.aspx?id=17851
and add it to your project. set its installation to run before the installation of your program.
I am about to release my pet project and let other people to use it. It is WinForm application that heavily relies on Win API.
Will people need to download Microsoft .NET Framework 4 Client Profile or will they need to have full .NET4 framework?
That depends on what framework version your project targets.
You can check that in the solution properties in Visual Studio but right-clicking on the project and choosing properties.
Since Microsoft .NET Framework 4 Client Profile is the framework runtime, that should be all that is needed. But as it says here ---> The Microsoft .NET Framework 4 Client Profile redistributable package installs the .NET Framework runtime and associated files that are required to run most client applications.
Then I guess it's a matter of what your using and you would have to test it on a machine that does not have .net 4 already.
