.NET Core 2.2 Can't be Selected In Visual Studio Build Framework

Question

Previously, I was able to select the .NET Core 2.2 Framework in the properties section of the .NET Core project, but after the latest visual studio updates I haven't been able to.

Things I've tried:

• Repairing the .NET Core 2.2 SDK installation
• Uninstalling and Reinstalling the .NET Core 2.2 SDK
• Restarting Visual Studio
• Restarting my machine
• Making a fresh .NET Core project

Nothing has been able to work. From the fact that it was working before I installed the latest updates, could it just be a bug? Or is there something that I'm missing?

For some more clarity, I'm running in Windows 10 Professional x64 on the latest version of windows.

I installed this version of .NET Core 2.2 from here

Any help is appreciated. Thanks!

Answer 1

Configure Visual Studio 2017 15.9 to use the previews of .NET Core SDK (in Options) and restart VS.

Update in 2019:

Microsoft decides that VS2017/2019 should use different .NET Core SDK versions, so make sure you do install the correct versions for your VS versions, and read the official announcement here,

https://github.com/dotnet/announcements/issues/108

You might find the SDK version/VS version table in .NET Core release notes, such as https://github.com/dotnet/core/blob/master/release-notes/2.2/2.2.4/2.2.4.md

Is a good practice to subscribe to the Microsoft .NET and Visual Studio team blogs so that you can always learn the new things, like https://blogs.msdn.microsoft.com/dotnet/2018/11/13/net-core-tooling-update-for-visual-studio-2017-version-15-9/

I have same problem. I am trying fix this issue about one day. Finally I figuret out. My VS version is 15.9.11 and Community Edition.

Issue details: 2.1.6xx & 2.2.2xx version of the sdks are only supported on Visual Studio 2019. VS 2017 needs 2.1.5xx & 2.2.1xx versions of the sdk.

How to fix the issue? Install 2.1.5xx version of the SDK if you are targetting a 2.1 app Install 2.2.1xx version of the SDK if you are targetting a 2.2 app.

The link is here

Edit: The direct link to downloadable installers is https://dotnet.microsoft.com/download/dotnet-core/2.2. As noted above, do check which SDK version is compatible with Visual Studio 2019 and/or Visual Studio 2017.

For example, if you want to use .NET version 2.2.7 in Visual Studio 2017 (v15.9), the only SDK version that works is SDK 2.2.109. To use SDK 2.2.206 you must have Visual Studio 2019 (v16.0). To use SDK 2.2.402 you must have Visual Studio 2019 (v16.2).

Answer 3

Visual Studio 2017 and 2019 require specific build versions. Missing these will give this error.

• 2017 uses x.x.100
• 2019 uses x.x.200

Latest sdk https://github.com/dotnet/core specific to each vs version.

https://github.com/dotnet/core/blob/master/release-notes/2.2/2.2.4/2.2.4-download.md

• 2017 install 2.2.106
• 2019 install 2.2.203

This resolved the issue

For anyone else landing here after searching for 'the current .net sdk does not support targeting .net core 2.2 ...' make sure you have the right platform selected for the download: Use x86 not x64 when running in Visual Studio in 32-bit mode (which is currently always the case).

Answer 5

Using 2017 15.9.11 with only 2.2.202 (run dotnet --info to see what is installed) I could not have 2.2 selected in the drop down and would get the error "The current .NET SDK does not support targeting .NET Core 2.2".

Once I installed 2.2.104 I was able to compile and select 2.2 in the framework selection drop-down.

Dear MS - VS is WAY TOO BUGGY LATELY. I really do not appreciate the instability of things since you have gone to agile.

Answer 6

Please choose the correct .net Core framework. Visual Studio 2017 v 15.9.12 compatible with .Net Core SDK 2.2.107 .SDK 2.2.300 compatible with Visual Studio 2019

Answer 7

If anyone has an error restoring a .net core framework dependency during a build with Azure DevOps (VSTS), it may be due to the build agent (Hosted VS 2017 in my case), not having the .net core SDK available.

I added the missing .net core SDK (2.2 in my case) by adding a build step as instructed by this blog post: Build .NET Core 2.2 Projects on Azure DevOps by Edi Wang

From Microsoft Docs

The Microsoft-hosted agents don't include some of the older versions of the .NET Core SDK. They also don't typically include prerelease versions. If you need these kinds of SDKs on Microsoft-hosted agents, add the .NET Core Tool Installer task to the beginning of your process. Azure DevOps Services

Answer 8

For people who are still stuck with compiling .net core apps after installing the latest .net core SDK.

TL;DR:

Depending on your Visual Studio version( 15, 17 or 19) you will need to install specific SDK version (which doesn't have to be the latest available).

so as of today, you may use the following links:

• For Visual Studio 2017 (version 15.9 or above), you will need to install SDK version 2.2.106
• For Visual Studio 2019 (preview or above), you will need to install SDK version 2.2.203

Full details:

Due to a change made by the Visual Studio team on how visual studio will utilize .net core SDK installed, there is a compatibility table that shows which SDK version is compatible with Visual Studio 2015/2017 and 2019.

This is the blog post highlighting the change: https://devblogs.microsoft.com/dotnet/net-core-tooling-update-for-visual-studio-2017-version-15-9/

To fix the issue you will need to make sure that you are using the SDK version compatible with your Visual Studio version.

Check the table on this page and only install the SDK version compatible with your visual studio version: https://github.com/dotnet/core/blob/master/release-notes/2.2/2.2.4/2.2.4.md

I am also facing same problem (core 2.2 framework not coming in target framework drop down) so to solve this problem follow following steps:

1. Install latest core version from here.
2. Find global.json file in folder (C:\Users[username]), change the version of core framework in this file.
3. Restart the visual studio.

Hope this will help you!

Answer 10

Update for VS .Net Core SDK 2.2.107

This page .net core downloads has link for 2.2.107 sdk specially for VS 2017. I needed this even though I could see the 2.2 core option from the project dropdown within visual studio.

Minor release increment but apparently they changed the underlying ms build github dotnet core which baulked vs 2017. Furthermore VS 2017 15.9.12 wasn't showing any further update requirements.

Also the global.json and project.json etc has gone and instead the csproj file is now used.

Answer 11

If you are getting this error when building:

The Current .Net SDK does not support targeting .Net Core 2.2 Target ...

Download the latest .NET Core SDK here:

https://dotnet.microsoft.com/download

Install it.

Find global.json file in folder (C:\Users[username]), change the version of core framework in this file (if needed).

Restart VS and try building again.
