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.
NET Standard 2.0 is supported by all modern platforms and is the recommended way to support multiple platforms with one target. If you need to support . NET Standard 1. x, we recommend that you also target .
In order to change default dotnet SDK version, place a global. json file in the current folder or any parent folder with the contents below. You can create the global. json file manually, or use the dotnet cli command dotnet new globaljson .
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.
