I am using the Setup Wizard to package my windows form app however when installing I get prompted to install the .NET 3.5 framework even though my app is built on 2.0 and the 3.5 framework is not ticked in the prereqs section of the setup project.
Why is it asking for .NET 3.5?
Solved: I have manually changed the framework version under Launch Conditions.

I'm developing a C#.Net application that uses the .Net Framework but I'm having trouble when users are installing the application on their computers. Some of them just don't know how to install the .Net Framework.
I'm searching for a solution to this problem and I found the self contained deployment use in .Net Core applications.
The problem is that my application doesn't use .Net Core, it is a WPF application.
I already search the web and all solutions I find brings me to the .Net Core self contained deployment.
What can be done in order to deploy a "self contained" .Net Framework application?
Thanks in advance.
You can use WiX to create a "bootstrap" installer, which will install required frameworks before installing your application.

Find a version of the .NET Framework that all of your target computers already have, and set Visual Studio to target that version of the framework.
Then, just copy/paste all of the files out of the bin/release folder into a folder on the target computer and run your program's executable.
If all of your target computers have Windows 10, you can deploy using version 4.6 of the framework, and be guaranteed that your clients already have it.
I have a project that targets both .Net 2.0 and .Net 4.5. I built+published it successfully in Visual Studio 2013. The .Net configuration in the .csproj file still says
<TargetFrameworkVersion>v2.0</TargetFrameworkVersion>
Yet, when I open the project in VS 2015, it targets .Net 4.5.
I have 2.0 available in the Target Framework dropdown:
when I click ".Net Framework 2.0" it gives me a popup saying
Changing the target framework requires that the current project be closed and then reopened.
Any unsaved changes within the project will be automatically saved.
Changing Target Framework my require manual modification of project files in order to build.
Are you sure you want to change the Target Framework for this project?
When I click yes, the target framework goes back to 4.5 and nothing else happens.
I've tried reopening the project and VS, with no luck.
I've tried running the .Net 3.5 installer (which apparently includes 2.0), but it says I need to use "Turn Windows Features on/off"
I've ensured the .Net 3.5 Windows Feature is enabled.
And now I'm out of ideas. Has anyone else encountered this?
Running Windows 7.
In case, the .NET Framework 2.0 is corrupted, use the .NET Framework setup verification tool: https://blogs.msdn.microsoft.com/astebner/2013/11/06/net-framework-setup-verification-tool-and-cleanup-tool-now-support-net-framework-4-5-1/ to verify and once it found any corrupted, you can use the .NET Framework Repair Tool: https://www.microsoft.com/en-us/download/details.aspx?id=30135 to repair it.
Or under ‘Turn Windows Features on or off’, uncheck .NET Framework 3.5 (includes .NET 2.0 and 3.0), then check it.
As Hans Passant mentions in the comments, I apparently(?) edited the .csproj to use different frameworks for different configurations. I swear this didn't cause any issues in VS 2013.
But in any case, I verified using ILSpy that the .dll being generated is .Net 2.0, even though the dropdown says 4.5. So I guess all's well that ends well?
I have developed a Windows Form application in .Net C# using visual studio 2013. I am very sure that I have selected .Net framework version 3.5 while creating the project, so that it can install on Windows XP sp3 as well.
I have created the setup file using Visual Studio installer plugin. But when I have tried to install it in a machine which have windows xp sp3 with .net framework installed, there is an error showing that it is required .net framework 4.5 to run this application.
I have tried recreating the app, but it didn't work.
Alryt.. I have figured it out myself...
Thank you dennis.. you gave me the clue...
It have to select from setup project properties--> Prerequisites...
that worked for me... :)
In Visual Studio, right-click your project (not the solution, but rather the concrete project), go to properties, select the "Application"-ledger and check what is selected as Target Framework. You should be able to select .Net Framework 3.5 as build target.
Right click on Setup Project > View > Launch Conditions. Over here, it was already referring to .Net Framework, Right click on it > Properties, change the version to .Net Framework 3.5. It solved the problem.
I recently upgraded my system to Windows 7 Enterprise. I have created an install package for a console application built with .Net framework 3.5 in VS2010. But when I try to install the msi on an XP machine, it gives me this warning that .Net Framework 4 is required.
Steps I tried to resolve the error:
Right click on Project and set the Target Framework to .Net Framework 3.5 in Application tab.
Right click on Project, Select Publish > Prerequisites > a) Selected .Net Framework 3.5 SP1 and b) Windows Installer 3.1
Right click on Setup Project, Prerequisites > a) Selected .Net Framework 3.5 SP1 and b) Windows Installer 3.1
Rebuild Setup Project to create msi.
All my above steps are futile since I am still getting a warning when I am installing the msi on an XP machine.
Has anybody got better idea to resolve this issue?
I think I have found the solution to this problem.

Install the full .NET Framework 4 on your XP machine

Dee you need to eliminate a few things. try constructing a 'blank' msi project with no dependencies in the manner described above and see if the resulting MSI requires .net4 on the target machine?
Secondly, what warning are you getting that .net4 is required? is it just the help link redirecting you to the generic .NET download page? if so, you can change this link to point to .NET3.5 SP1 specifically.
if i have an application that requires .net 3.0, what is the proper way to make an install file out of it, that will install the application and then install (activate) the .net 3.0? i tried publishing my project through visual studio 2008 (c#) which created the installer and the .net activator, but it didn't work properly on computers other than my own, when the .net 3.0 was not present.
i though i could bundle http://www.microsoft.com/downloads/details.aspx?FamilyID=10CC340B-F857-4A14-83F5-25634C3BF043&displaylang=en with the application, which would download and install .net 3.0 if needed. this could work ok on non-vista systems, but on vista, the redist package reports an error: you must use turn windows features on or off in the control panel to install or configure microsoft .net framework 3.0
The key is to install the .net framework if it is not there - regardless of the OS. Also, just go ahead and install the .Net 3.5 framework if you are going to install one of them.
Anyway, if you are using the built in installer that comes with Visual Studio, this is a real pain in the butt. You would be better off, and saner if you went with a different installer package. Install Shield, Wise, InstallAware will all do it for you. I believe you can also find better guidance on how to do this with Wix and NullSoft Installer.

How can I detect .NET 3.5 in WiX?
Windows Vista has already .NET Framework 3.0 installed.
Now if you wanted for example to have .NET Framework 3.5 installed you could create a Setup Project and then right click and go to View->Launch Conditions. There will be a .NET Framework launch condition where you can specify the required version of the framework and an URL to download from.
Here's a post about Launch Conditions in a Setup Project.
