I have migrated a project from .NET Framework 4 to .Net Framework 4.5. When I create the setup project, and run the installer, i get the error message "This setup requires .NET Framework version 4.5". This is the version used in each project and it is installed on my local machine.
How can this problem be solved?
If you use Visual Studio :
Select Project -> Properties -> publish -> required components
and make sure Net Framework 4.5 is selected

I created my initial project that targets Framework version v4.7.2. I needed to add a class library in my project using visual studio 2022 Community. While doing so, VS2022 gave me only 4 options to choose from for setting Target Framework (.Net Standard 2.0, .Net Standard 1.0, .Net 5.0, .Net 6.0). This feature isn't there in VS2019 Community. I selected .NET 5.0
Now this class library cannot be referenced by my initial project. I think I need to update .NET Core SDK but don't know which version (if I am correct in my assumption).
Please help. Thanks
You should add a class library, which is supported .NET Framework.
In the one project, all classes are the same target output (.NET Core or .NET Framework)
Referred project and reference project are the same target output.
My case:
I created Winform Application(.NET Core), then add Junit Project(.NET Framework) referring to Winform Application and they are conflict due to different target.
My Solution:
I changed Winform Application from .NET Core to .NET Framework and they are working.
Hope to help you!!!
I have installed .NET core 3.1 and verified i can run .NET core 3.1 apps on my machine however when i go to create a new project the dropdown for target frameworks only allows .NET 6.0. I am using visual studio 2022. I am using visual studio 2019 on my laptop and i can add .NET core projects just fine.
Has anyone ran into this?
Open Visual studio installer from start menu
Select Modify from Visual Studio that you want to add
in individual components select .net core or framework that you want to add to your visual studio version
Create the app in either 5 or 6. Then in the Application properties change the Target Framework to .Net 3.1.
Long term support is limited for anything before .Net 5, so they are not making it an option on new projects and directing to the newer versions.
I'm using VS2022 and was facing the same issue. I installed the .NET SDK 3.1.416 from here and restarted the VS. I am now able to create project with .NET core 3.1 target framework.
When I create a Project in Visual Studio, I can't choose .net framework as my target framework, I only have the choice between .net core 3 and .net 5, I have already downloaded and installed .net framework 4.8 Developer Pack but nothing changed.
You need to pay attention to the template you create your project with - some are e.g. "Console App" (which is for .NET Core - 3.1 or 5.0), while another might be called "Console App (.NET Framework)" which is for the various versions of the full, classic .NET framework:
If you picked the .NET Core template - then yes, you cannot target the "classic" .NET Framework - just create the correct project type from the correct template and you should be fine
When creating a project in VS2015 it asks you the target .NET framework version. I chose .NET 4.6 but now I want to revert back to 4.5. In the past, you were able to change the target framework version from the project tab but now in asp 5 it seems like there is no way to do it ? Any ideas ?
In order to change the target framework you need to change the dnx entry in project.json. You can upgrade from 4.5.1 to 4.6 by changing "dnx451" to "dnx46".
Be aware that there are still some problems running latest framework version in web environment. E.g. IIS not picking up .NET 4.6 and running in 4.5.1 by default as explained in this this answer.
Right click your project (not solution) -> select properties -> under Application tab select Target Framework -> change to desired framework.
I am using VS 2010 and i was trying to create program based on .Net Framework 4 and when i done it, program was working only on my computer, coz nobody of my friends don't have .Net framework 4 installed.
How to recompile program for .Net Framework 3 in Visual Studio 2010?
right-click on the project properties and change Target framework from .NET Framework 4 to .NET Framework 3
Go to the Project menu
Click on the Your Project Properties
On the Application Tab, select .NET Framework 3.5 from the Target Framework dropdown.
Simply change project settings.
Or use command-line csc to compile
You can switch the target framework in Visual Studio 2010 between .NET 2.0, 3.0, 3.5, and 4.0.
See How to: Target a Specific .NET Framework Version or Profile on MSDN.
As noted on that page, you might have to install 3.0 by hand since Visual Studio 2010 comes only with .NET 4.0. But once you install 3.0, you will be able to target it.
From the project in Visual Studio 2010, right click on the project and select Properties. Click on the Application tab, and from the Target Framework dropdown, select .NET Framework 3.0.
Project ->
Properties ->
Application (tab) ->
Target framework: .NET Framework 3.0
This MSDN page will help guide you with additional details.
And, not to be a schmuck, but you could have received a faster answer by Googling "compile .net framework 3.0 visual studio 2010" and noting that the first link is How To: Change the Target .NET Framework.
