When using a ClickOnce installer, will it include the necessary .NET framework?
For instance, I want to distribute a WPF application that uses the System.ComponentModel namespace, which wasn't included until .NET 4.5. If I ran the ClickOnce on an older version of Windows that only had up through, say, .NET 3.0, would it still work?
The click once application will depend on the .NET 4.5 framework. You can include this as a redistributable through project settings -> publish -> prerequisites. In fact I think recent VS versions will already prepare a setup package to run through installing this during the pre-reqs section of your installer. You can even alter the location of where the redistributable package comes from.
In summary. It will "work" in that when someone runs your installer it will tell them they don't have the correct pre-reqs, and offer to install .NET 4.5
It will, if you install with the setup.exe installer. I haven't tried it for some time but it always worked like this.
If you link directly to *.application manifest, the .net framework and other dependencies will not be installed automatically.

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'm working on upgrading a windows application/service to target newer .NET frameworks for a client. This is the first time I've done anything of the sort. I changed the Target Framework in the C# project's properties window to 4.5, rebuilt the project without any errors, and then tried to run setup.exe. When I run this, it says:
This setup requires the .NET Framework version 2.0.50727.
Does anyone know why this would be happening? I read about launch conditions and that it could possibly be checking that the client computer requires v2.0, but I don't see an option to view the launch conditions in Visual Studio 2013.
Thanks
I have created an installshield project using the Limited edition 2012 of InstallShield.
My application uses the Microsoft Agent 2.0 control in some places. So my question would be :
How do i run the Agent installer from my install wizard? Either before the main app is installed or after...
Also, i have set a prerequisite on the setup project to include .NET 4.5 and the installer to require .NET 4.5...but if i uninstall .NET and run my setup, it simply says i need the .NET Framework, rather than installing it...any ideas?
Add a prerequisite installer for agent. And keep the one for.net, it shouldn't install if it is already present. If you don't need .net then look for a install condition that is requiring it.
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 a setup project which, as a prerequisite, requires the .Net 4 framework installed locally on the target machine. I specify the install location for prerequisites as "download prerequistes from the same location as my application" resulting in the dotNetFx40_Full_x86_x64.exe being added to the installer (since the target machines we install to are not connect to a network, i.e. standalone).
I'd also like the installer to recognise it needs to install any updates of the .Net 4 framework to the standalone target machine if required. What is the best way to accomplish this?
Thanks in advance.
If you know what updates are required, the simplest way to do it is probably just to create new bootstrapper packages for the standalone updates, and add them as additional prerequisites. There's more info on that here:
