The current NET SDK does not support targeting NET Standard 2 0 error in Visual Studio 2017 update 15 3

Question

I want to create a class library project with Target Framework  NET Standard 2 0    I ve updated my Visual Studio 2017 to Version 15 3 and also in Visual Studio installer checked  NET Framework 4 7 SDK and  NET Framework 4 7 targeting pack manually and installed them   There is still no  NET Standard 2 0 option in the Target Framework combo box in the Project Application window  So I changed TargetFramework tag in  csproj file manually to netstandard2 0  but after trying to build I get this error      The current  NET SDK does not support targeting  NET Standard 2 0     Either target  NET Standard 1 6 or lower  or use a version of the  NET   SDK that supports  NET Standard 2 0

I had installations of both Visual Studio 2019 and 2017. I tried installing the .NET Core 2.X SDK for VS2017 separately but with no luck.

The issue is, that I have .NET Core 3.0 SDK installed as default sdk-version, which VS2017 does not like.

My solution was to switch the SDK version for the specific project.

First, list your installed SDK's to find the desired version:

$ dotnet --info

.NET Core SDK (reflecting any global.json):
 Version:   3.1.100
 Commit:    cd82f021f4

Runtime Environment:
 OS Name:     Windows
 OS Version:  10.0.18362
 OS Platform: Windows
 RID:         win10-x64
 Base Path:   C:\Program Files\dotnet\sdk\3.1.100\

Host (useful for support):
  Version: 3.1.0
  Commit:  65f04fb6db

.NET Core SDKs installed:
  1.1.14 [C:\Program Files\dotnet\sdk]
  2.1.202 [C:\Program Files\dotnet\sdk]
  2.1.509 [C:\Program Files\dotnet\sdk]
  2.2.110 [C:\Program Files\dotnet\sdk]
  3.0.100 [C:\Program Files\dotnet\sdk]
  3.1.100 [C:\Program Files\dotnet\sdk]

From your solution directory:

$ dotnet new globaljson --sdk-version 2.2.110 --force

Now, dotnet will use the specified SDK version for this solution.

I have not found a way to do this system-wide without also messing up my 3.0 projects.

I just had this with 15 8 3 after uninstalling some  NET Core 1 x preview SDKs  my application would not compile and showed the error   It was fixed by installing the latest x86 version of the SDK even though I m on Windows 10 x64   I presume this is because VS 2017 is still a x86 program and though the programs run as x64 the compiler was looking for an appropriate x86 SDK

It sounds like installing the VS2017 update for that specific version didn t also install the  NET Core 2 0 SDK  You can download that here   To check which version of the SDK you ve already got installed  run  dotnet --info   from the command line  Note that if there s a global json file in either your current working directory or any ancestor directory  that will override which version of the SDK is run   That s useful if you want to enforce a particular version for a project  for example    Judging by comments  some versions of VS2017 updates do install the  NET Core SDK  I suspect it may vary somewhat over time

When I upgraded Visual Studio to version 15 5 1   Net Core SDK was upgraded to 2 X  so this error went away  When I run dotnet --info  I see the following now

Actually  to me it happened in opposite way to another answers   I did install the latest  NET Core SDK before the issue appeared  3 0 0-preview2 in my case  having not the latest version of Visual Studio  not sure if that would make any difference    So  the solution was just to uninstall that latest  NET Core SDK   This is not perfect if you need it  so you might consider Visual Studio upgrade to the latest one  but at least that solved ongoing issue

For me the solution was to change the version in global json to reflect the installed one    Like the others said the version can be found running dotnet --info in cmd  This        projects      src    test        sdk          version    2 0 3          Became        projects      src    test        sdk          version    2 1 4          You can also create the global json file by running   dotnet new globaljson --sdk-version 2 1 4   at root of project
