First of all, The Winform application is based on .Net Framework 1.1. I have 1.1 SDK installed but 1.1 is not listed in the Target Framework(VS 2010 Beta 2) so I cannot choose the same, the minimal available is 2.0. Am I supposed to install an add-on or something for building 1.1 apps in VS 2010 beta2. Further more, I am using a Clickonce deployment publish method. I am not sure if 1.1 supports ClickOnce deployment. Please advise on both these fronts. Thanks a Lot
.NET 1.x is not supported by VS2010 (or any future versions). You'll have to use VS2002 or VS2003 for that.
ClickOnce is only supported for .NET 2.0 or later.
.Net 1.1 isn't supported on VS 2010. I don't even thing it was supported on VS 2005 or 2008. I've always had a VS 2003 install in a VM for 1.1 maintenance stuff.
Here you can find a way to create your project in .net 1.1 with VS 2008. And I think this is last version of the VS you can use to create your projects in .net 1.1
If you have an application that uses e.g. an app pool using .Net 1.1, compiling for .Net 2.0 simply isn't an option.
You should just build your code with .NET 2.0, assuming there's some reason why you can't build it with .NET 3.5.

What can be the reason that install is greyed out?
Microsoft Istaller projects 2022 is installed. Solution can build without problems.
It's an old project where .net Framework 4.0 is used.
I'm just guessing, but it might be that .NET Framework 4.0 is deprecated and support was removed. You can't even install it via the Visual Studio Installer's Individual Components. The lowest 4.x targeting pack version I could install is 4.6.
Try installing the latest .NET Framework targeting pack and then re-target the project to use that.
I have downloaded and installed .NET Core 5.0 SDK (v5.0.100-preview.1) in my Visual Studio 2019.
But it is not available in Target framework.
Am I missing something?
You need to install the latest preview of Visual Studio 2019 16.8, refer to
https://devblogs.microsoft.com/aspnet/asp-net-core-updates-in-net-5-preview-1/
You also need to explicitly enable preview versions within Visual Studio itself:
Then you should see it:
Specs: VS Version 16.8.0
Target Version of .Net Core: 5.0
You must have version 16.8.0 in order to have .Net Core 5.0
If you still have problems with Visual Studio not showing .Net Core 5.0 in Visual Studio version 16.8.0 (and assuming you downloaded the .NET Core 5.0 SDK for Visual Studio), well, apparently (and correct me if I'm wrong) it is now called just .Net 5.0, omitting the Core.
After selecting .NET 5.0, I was able to install other libraries which are currently version 5.0+ and dependent on .NET Core 5.0+
Is the new name intentional? Anyways, here some evidence of this working (I was able to install the newest version of Newtonsoft and Entity Framework for .Net Core):
Funny enough, when I try to create a new .Net Core project, the version shows up as expected:
I upgraded my version of Visual studio from 16.7.x to 16.8.1. I expected NET 5 to be listed as a target framework, but it was not.
I had previously created projects in 16.8 preview 6 using RC1.
Visual Studio Install did not list .NET 5 as an individual component either. I then downloaded and installed the x64 SDK. Still no luck. .NET5 was still missing as a target framework for VS 16.8.x
Today I opened VS Installer and from the More dropdown menu selected Repair . The repair process took 25-30 minutes to run, but now .NET Core 3.1 and .NET 5 are listed in all the usual places.

Maybe a bit late to the party.
Please note that if you've selected a 'regular' .NET Framework application you won't see the .NET 5.0 Framework option.
This is only visible in .NET Core project styles.
Try to set it in your .csproj file. Right click (maybe unload) and edit (within a PropertyGroup-element):
<TargetFramework>net5.0</TargetFramework>
Targeting .NET 5 (rc2) doesn't work smoothly in VS Version 16.8.0 Preview 6.0
I could only target .NET 5 by manually changing the .csproj file, and adding:
<TargetFramework>net5.0</TargetFramework>
When I wanted to create a solution, .NET 5 was not available, even when I have it installed. What I did to fix this was:
When you are creating the project, select the last version (in my case .NET Core 3.1)
When the project is created, right click on the project and select the Properties option.
In the Application tab, select the Target Framework you want.
I have installed Visual Studio 2012 Express, and .NET Framework 4.5 got installed together.
Now from Visual Studio 2012, also if I target .NET 4.0 (Properties->Application->Target Framework), that doesn't seem to work. (The same happens from Visual Studio 2010, which by the way cannot target 4.5 at all!).
What I have noticed is that if I debug my project, and set a Watch on a SqlConnection variable, I see all the new 4.5 member properties (for example I see SqlConnection.ClientConnectionId property, introduced with .NET 4.5).
So, what is Visual Studio -> Properties -> Application -> Target Framework -> 4.0 supposed to do?
This 'strange' behaviour looks, in fact, perfectly normal when you realize that the installation of .NET Framework 4.5 is a replacement of .NET 4.0.
Look at Stack Overflow answer Can a build server with .NET 4.5 installed successfully deploy a project targeting 4.0 to a server with only .NET 4.0 installed?.
I have read that opening a vs2010 project in vs2012 is fine (as long as you are using VS2010 SP1) it will not update the project files and those on VS2010 SP1 will not have problems using it: http://visualstudiomagazine.com/articles/2012/03/01/more-power.aspx
However I have heard that the version of .net 4 is higher when using vs 2012 than with vs2010 (I don't mean .net 4.5 by the way). Is this correct and could it cause problems with a release on a development machine being tested against a different version of the .net 4 framework? It sounds a bit unlikely to me.
thanks

The answer is not simple. All the details can be found here
There are many different types of projects in VS, and some don't require upgrades, some are compatible but require upgrades, and some are simply not compatible. It depends on the project type.
Also, to answer your question about the .net versions, 4.5 is considered an "in place" upgrade. This means once you've installed 4.5, it replaces 4 completely. So, once you've installed 4.5 you use that any time you target 4.
Several bugs has been fixed with .NET 4.5, so suddenly you cannot reproduce bugs that people experience in live-environment (WinXP/Win2k3 - .NET 4.0), as your own machine that have VS2012 installed (.NET 4.5).

I am working with a project which uses .Net Frame V1.1 runs on VisualStudio 2003,
Now, I want to run my project in VisualStudio 2010?
Can I still target .NET Framework 1.1 in VisualStudio 2010?
Visual Studio 2010 only supports the 2.0, 3.0, 3.5, and 4.0 frameworks as targets. It does not support 1.1.
Is there any reason why you can't upgrade it to .NET 2.0. Did you know that .NET 1.1 is no longer officially supported on Server 2008 R2 and so I wouldn't expect it to be officially supported on any newer operating system.
I have read of some hacks to build .NET 1.1 projects for VS2005 and VS2008 - see below. Realize that if you set this up, then everyone else who works on the project will have to go through the same setup.

No, .NET Framework 1.1 is not supported by Visual Studio 2010.
