I want to work with visual studio 2019 net5.0 framework but there is a little message like this on page => (Net 5.0 out of support) .Is Net 5.0 framework banned from microsoft ? or cancelled ?
help me guyss.
Thanks ........
I hope somebody answers my question.
As Timothy G said. Microsoft will no longer provide servicing updates for .NET 5.0, including security fixes or technical support, and users will need to update their .NET version to a supported version (.NET 6.0) to continue receiving updates.
.NET 5.0 is not an LTS release, so will end support 18 months after release or 6 months after the next release. When .NET 5.0 support ends, applications using this version will continue to work, but the related vulnerabilities may not be fixed as Microsoft only provides support for the supported versions of .NET (ie. .NET Core 3.1 and .NET 6.0) Release a security update. Therefore users are strongly advised to migrate their applications to .NET 6.0.
Upgrade to .NET 6.0
Open the project file (.csproj, .vbproj or *.fsproj file).
Change the target framework value from net5.0 to net6.0, the target framework is defined by the or element.
For more migration matters, please refer to the .NET 6 Compatibility Guide: https://docs.microsoft.com/dotnet/core/compatibility/6.0.
Visual Studio 16.11 will continue to support .NET 5.0 SDK versions until the end of support for .NET Core 3.1 in December 2022. However, the .NET 5.0 SDK does not use the .NET 5.0 runtime when running command-line scenarios, and is not available as a standalone SDK. It is recommended to use .NET 6.0 and Visual Studio 2022 to build applications that run on supported .NET runtimes.

We have close to 30 apps running on .net framework 4.5.2
Can someone explain the following paragraph from Microsoft site (https://support.microsoft.com/en-us/help/17455/lifecycle-faq-net-framework) in simple terms
It says "Beginning with version 4.5.2 and later, .NET Framework is defined as a component of the Windows operating system (OS). Components receive the same support as their parent products, therefore, .NET Framework 4.5.2 and later follows the lifecycle policy of the underlying Windows OS on which it is installed. "
If we keep upgrading our Windows server OS, will there ever be a need to upgrade the framework? I assume Microsoft will keep sending security patches for 4.5.2.
UPDATE
Microsoft just announced end-of-life for .NET 4.5.2, 4.6, and 4.6.1: April 26, 2022.
https://devblogs.microsoft.com/dotnet/net-framework-4-5-2-4-6-4-6-1-will-reach-end-of-support-on-april-26-2022/
Original Post
See this page for what OS versions are supported for each .NET version: https://learn.microsoft.com/en-us/dotnet/framework/get-started/system-requirements
From how I understand it, .NET 4.5.2 goes out of support when Windows 8.1 goes out of support, as it is the last Windows OS where .NET 4.5.2 is officially supported.
Therefore, .NET 4.5.2 goes out of support on January 10, 2023.

.NET Core 2.2 Can't be Selected In Visual Studio Build Framework
(12 answers)
Closed 4 years ago.
I wanted to try the .net core 3.0 preview. However after downloading the .net core 3.0 preview SDK, my VS 2017 15.9 didn't show the .net core 3.0 on target framework when I wanted to create a .net core asp.net web application or wanted to upgrade the .net core 2.2 web app to 3.0.
Here is what I found out and wanted to share here in stackoverflow. So if someone experience same issue and looking for solution, it can be found sooner and hope it helps to save their time.
From Microsoft:
"Starting with Visual Studio 2017 version 15.9, we’ve changed how the Visual Studio tooling for .NET consumes .NET Core SDKs. Prior to this change, installing a preview version of the .NET Core SDK would cause all Visual Studio tooling for .NET Core to use that SDK because it had a higher version."

We are still using VS 2010 SP1 to develop a large scale LOB ASP.NET web application. The infrastructure folks are looking at pushing .NET 4.6 (and the targeting pack to devs) to the desktop and I am having trouble finding anything on compatibility with VS 2010. One of the leads here said the two are incompatible and cannot be used together and that you must have VS 2012 or higher but I can't find anything official on the topic. Anyone know if it is possible to use .NET 4.6 and VS 2010 SP1 for development?
Visual Studio 2010 does not support the 4.6 targeting pack. When the targeting pack is pushed to the machine, Visual Studio 2010 will not see it.
Now, this isn't actually a problem if you want to remain on a supported version of .NET (which is probably why your infrastructure folks are doing what they are doing), because even if you target 4.0, you can remain supported by deploying 4.6 and running your 4.0 application on it. We shim 4.0 behavior in this case, so when you're testing on a machine with just 4.0, you can be guaranteed that the application will run with high confidence on 4.6.
However, what I see devs run into a lot, is when they target 4.0, but test on a machine with 4.6 installed, then expect to be able to deploy to 4.0 and have this just run. In this case, there's not a 100% guarantee that this will work as we do not shim every single bug fix and/or feature. This means you can accidentally pick up 4.6 behavior, and rely on it.
To summarize:
If you target 4.0, test on 4.0 and deploy to 4.0/4.6 -> We guarantee that this works with pretty high confidence.
If you target 4.0, test on 4.6 and deploy to 4.6 -> We guarantee that this works with pretty high confidence.
If you target 4.0, test on 4.6 and deploy to 4.0 -> This will work in most cases, but you could accidentally depend on "fixed behaviors" that aren't fixed on 4.0.
Visual Studio does support multi-targeting. For example, if I were using Visual Studio 2012 I could install the 4.6 multi-targeting pack to develop a 4.6 application.
However, the download instructions for the 4.6 multi-targeting pack do not mention support for Visual Studio 2010, just 2012 and 2013:
The .NET Framework 4.6 Targeting Pack is a package that enables developers to build applications targeting the .NET Framework 4.6 by using either Visual Studio 2013, Visual Studio 2012 or third-party IDEs
That's as close to any documentation as I've found. This leads me to believe that no, support for 4.6 multi-targeting does not exist for Visual Studio 2010.
Wiki contains a cross reference of visual studios and .net versions they support.
MS Visual Studio History
Each new version of .NET comes with more than just a new compiler. New Tools, Projects, and even IDE functionalities are added too. If you must use the features of 4.6, you should look into upgrading your VS too.
I have old Web Client Software Factory project built with VS2008, WCSF 2008 and MS Enterprise Library 3.1
I have to make changes to the project so I migrated the solution to Visual Studio 2012. It compiles fine with .NET 3.5 and runs on IIS 7.5 as 32bit web application (classic mode asp.net v2.0).
Is it possible to migrate such project to .NET 4.5 (64 bit)?
My guess is no. The last version of WCSF is 2010 and for the MS Enterprise Library is 5.0.
I think they both are built on .NET 3.5
Did anyone try such migration before?
Thanks
I'm planning to do the same thing for couple of my applications.
I did checked out on MSDN and the WCSF project discussion on codeplex seems there's no future roadmap for this WCSF.
See:
Web Client Software Factory
Roadmap for 2012 and beyond ?
Microsoft provides a number of command line tools for working with asp.net applications. I haven't had any trouble using these tools. One thing that I can not understand though, is the location of these tools.
Even for applications targeting newer versions of .net, these tools are located in the .net v2 directory. On my machine, that's C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727. Why do these tools not exist in the v3.0 or v3.5 directories? And why do the ones in the older directory work on the newer framework?
This is more of an idle curiosity than required knowledge for me, but I would like to know.
Update:
Thanks for the good answers everyone. These answers raise a new question though. I hope you will forgive me for asking it here, since it is so highly related. If .net 3.5 is really just using the CLR from 2.0, why is 2.0 compatible with Windows 2000, but not 3.5? It would seem to me that if the updates in 3.0 and 3.5 run inside the framework of the earlier version, then they must maintain compatibility with the same platforms as the earlier version too. Why is this wrong?
.NET 3.0 and 3.5 are (basically) just library additions to the 2.0 framework.
The addition of .NET 3.0 didn't mean new compilers or a new CLR. Instead, it's three major new libraries: WCF (Windows Communication Foundation née Indigo), WPF (Windows Presentation Foundation née Avalon) and Windows Workflow or WF.
Basically, remember Framework version != CLR Version. If you configured an IIS Application to use .NET 2.0, you're talking about the 2.0 CLR. WCF Applications use the .NET 2.0 CLR with the new 3.0 WCF libraries.
* .NET Framework 1.x = CLR 1.x
* .NET Framework 2.0 = CLR 2.0
* .NET Framework 3.0 = CLR 2.0
* .NET Framework 3.5 = CLR 2.0 + (C# 3.0 | VB9)
Edit:
To answer your second question, .NET 3.0 and 3.5 have new libraries which reference OS-level features like WPF, which isn't available on Windows 2000. If you write an application in 3.5* but only use functionality and libraries that were also available in 2.0, it can still work on Windows 2000.
*by "in 3.5", we mean write it in Visual Studio 2008 under 3.5 but set your Project Target Framework to 2.0. Scott Hanselman talks about doing this to get ASP.NET MVC to work on .NET 2.0.
It is because the core of .Net has not actually been changed since v2.0. MS marketing types were much derided at the time for forcing the naming scheme in use, where .Net 3, and .Net 3.5 are really just adding additional libraries that run on the .Net 2 core.
Check out Scott Hanselman's blog post for more details.
Because .NET 3.0 and 3.5 are applications of .NET 2.0, not complete, standalone frameworks unto themselves. This is further see in the IIS config, where you only have the option to select .NET 1.0, .NET 1.1, and .NET 2.0. You web.config file will include any .NET 3.0 or .NET 3.5 assemblies as these are written, ultimately, with .NET 2.0 code. More details about that can be seen here: http://www.hanselman.com/blog/HowToSetAnIISApplicationOrAppPoolToUseASPNET35RatherThan20.aspx
Of course, that all changes in .NET 4.0 which will be a completely "new version" of the framework.
v3.0 and v3.5 still uses the v2 DLLs for the core files. Most of the changes are additions to the v2 framework as well as a new compiler for 3.5.
