For my project I'm required to target Microsoft .NET Framework 4.5, but am unable to do so.
Installed programs:
Whenever I try to install .NET Framework 4.5, it tells me it's already installed:
Make sure you have installed the latest update to Visual Studio 2013 which is Update 4. If it is installed, then do another install but select repair. Restart if necessary and try again.

** /Applications/Visual Studio.app/Contents/MonoBundle/MSBuild/Current/bin/Microsoft.Common.CurrentVersion.targets(5,5):
Error MSB3971: The reference assemblies for ".NETFramework,Version=v6.0" were not found. You might be using an older .NET SDK to target .NET 5.0 or higher. Update Visual Studio and/or your .NET SDK. (MSB3971) **
Although I have udpated the visual studio but its trowing same error again.
Install .NET 6.0.10x SDK. That will solve the problem.
I have installed both .NET CORE 3.1. and preview 5.0. I see it when I type command:
dotnet --list-sdks
I see all packages
but when I want to use it in VS project in C# .NET CORE console app I cannot.
I have not tried .NET CORE 3.x with VS 2017 but according this page it is possible that is is supported only in VS 2019.
You might also try to restart Visual Studio. I think it loads installed frameworks only during startup.

I'm having problem with LC.exe when building our application in Visual Studio 2013. When I started searching for LC.exe, I found the latest one installed under "c:\Program Files(x86)\Microsoft SDKs\Windows\v8.1A\bin\NETFX 4.5.1 Tools". I have both 4.5.1 and 4.5.2 installed. But I don't see a "NETFX 4.5.2 Tools" folder anywhere. When I uninstalled 4.5.1, all those tools are gone, and the latest LC.exe I can get is for .Net 4.5, which I also have installed. But where is the one installed by 4.5.2? I've tried removing and reinstalling 4.5.2 and still cannot find any tools from it. Does this mean I have to have both 4.5.1 and 4.5.2 installed? Is there a list of files (and installed paths) installed by each of the .Net pack? I understand from 4.0 onward .Net install should be in-place replacement, but I think the LC.exe in 4.5.1 path is 4.5.1, not 4.5.2 version (with version number 4.0.30319.33440).
Thanks for any info or pointers!
the latest LC.exe is contained in Windows SDK for Windows 8.1, which is installed by Visual Studio 2013. Unfortunately, it is installed under the folder name "NETFX 4.5.1 Tools". This is confusing because when .Net environment 4.5.2 comes out, people would expect a folder of "NETFX 4.5.2 Tools". Turns out, there is NO 4.5.2 tools. A page from MSDN explains what's included in where fairly clearly: http://blogs.msdn.com/b/dotnet/p/dotnet_sdks.aspx#.
I have installed .NET framework 4.0 on my system , but when I open my project on VS 2010 , still getting the message ,
This Project is incompatiable with the current version of Visual Studio
Any Idea? I don not want to change the target framework to v4.0 in .csproject.
The error you are getting is not about an incompatible .NET framework version, it is about an incompatible Visual Studio version!
Visual Studio project versions are not linked to .NET versions. A Visual Studio 2008 project can target .NET 2.0 up to 3.5, but still you can't open a VS 2008 project with Visual Studio 2005, even though Visual Studio 2005 can create .NET 2.0 projects, too.
Having the latest .NET framework on your machine does not guarantee that you can open projects with the latest Visual Studio version in an older Visual Studio.
You can simply not downgrade Visual Studio projects easily. There are posts describing how to to it by modifying the project files, etc., but in general you can only upgrade projects using the wizard that's automatically opened by Visual Studio.
As I know you can't target .NET 4.5 with VS2010 the same way you couldn't target .NET 4.0 with VS2008. You will need to install VS2012 if you want to target .NET 4.5.
EDIT
found this answer but haven't tried it by myself
I have installed Visual Studio 2012 Professional on my machine. I don't have Visual Studio 2010 installed, but I want to keep developing my applications using .NET Framework 4, but I don't have this option on my Visual Studio 2012. Look at the image:
I don't know what can I do to fix this problem, because I click on "More Frameworks..." link and try to install the Multi-Targeting for .NET 4.0.3 (installed on my machine), but it does not work. It says that this version of framework is still installed. What can I do to fix this problem?
Obs: I have lots of projects in C# and VB.NET with .NET 4.0, and I need to keep these projects with new projects on .NET 4.0.
I solved the problem doing these tasks:
Uninstall the Visual Studio 2012
Uninstall any reference for the .NET Framework 4.0 or 4.5
Clean the register with a tool like Glary Utilities and restart the computer
Install the .NET Framework 4.0 and install Microsoft Multi-Targeting for .NET Framework 4.
Install Visual Studio 2012 again
You fixed your problem, but it's likely that .NET Framework 4 Targeting Pack (not to be confused with the .NET Framework itself) failed to install for some reason. Did you get a warning at the end of the Visual Studio installation? Either way, in the future, a repair install of Visual Studio 2012 should have fixed the problem (Add or Remove Programs -> Microsoft Visual Studio [Edition] 2012 -> Change -> Repair).
I think that your issue is probably some mishap with the installation of .NET Framework. I installed Visual Studio 2012 Beta and have all kind of troubles with compatibility between framework versions. The only remedy was reinstalling Visual Studio, including .NET Framework.
Check out How to: Target a Version of the .NET Framework (MSDN).
After creating new a project, go to its properties (select your project in Solution Explorer then right click and select properties) and select the target framework!
