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 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.
For more support content, please view the official announcement: https://devblogs.microsoft.com/dotnet/dotnet-5-end-of-support-update/.
I have a complex project using .NETFramework,Version=v4.0 which I cannot migrate to .NET 4.5 because that requires VS 2012 or higher which I do not have, I only have VS 2010.
I just want to upgrade my ASP project to reCaptchaV2
I get this error:
The primary reference "Recaptcha.Web" could not be resolved because it was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".
What can I do to resolve this issue?
Is there a version of Recaptcha.Web targeted at 4.0 or lower that I can use, please!
Download Recaptcha.Web source code from https://github.com/tanveery/recaptcha-net/blob/master/README.md ; compile the .NET 4.0 version they have there using your VS 2010 targeted to .NET 4.0 ; grab the Release DLL you just created and put it where it can be accessed by your projects ; in VS keep your project target at .NET 4.0
I installed MS visual studio community 2017 along with all the necessary plugins but when I am trying to create a web application in C# only the .net frameworks upto 3.5 are available and as a result I can not create MVC based C# web applications because only the option empty web application appears. I installed the .net framework 4.6.2 development pack separately but even that the issue could not be corrected. How can I solve this issue?
We have asp.net 1.1 framework application is in live environment with appx 200 users.
Which visual studio version is safe to use for maintenance?
We are not planning to migrate yet. I am using vs 2008 for developing a 3.5 application right now so not want to take the risk of visual studio conversion.
You can check with visual studio2005 version
Use Visual Studio .NET 2003 and MSDN Library of Jan 2006.
I think you can use any Visual studio once your project is targeting the correct framework. This Post talks you through installing aspt 1.1 on a windows 8 machine.
Our current environment is .NET 3.5 SP1 but we're in the process of migrating to .NET4 and Visual Studio 2010.
I would like to stick to using .NET 3.5 for the deployment/production environment however use Visual Studio and TFS 2010 for development, until the production environment is cleared for upgrade to .NET4. Is this possible (I assume yes :B), and how?
What I have tried is changing the TargetFrameworkVersion in the project settings to "v3.5". However, I get a build failure due to the classes in System.Web.Security that moved to System.Web.ApplicationServices in .NET 4 (e.g. MembershipUser) not being found... so it appears that it is using .NET4 libraries and not .NET3.5? Do I add the System.Web.ApplicationServices library to my project, and if so, does this mean it will still run on .NET 3.5?
Also, I noticed that the ToolsVersion of the project is 4.0, would changing it from 4.0 to 3.5 be the correct thing to do? When I do this, re-opening the project causes Visual Studio to run the conversion process, changing the ToolsVersion back to 4.0 ...
Cheers,
James
You must have Visual Studio 2008 installed to be able to target .NET 3.5 in Visual Studio 2010.
