The current .NET SDK does not support targeting .NET Core 2.1. Either target .NET Core 2.0 or lower, or use a .NET SDK that supports .NET Core 2.1

Question

have tried upgrading to the professional version of visual studio 2017 v 15.6.0 (Preview 7.0)

and installed aspnetcore-runtime-2.1.0-preview1-final-win-x64 and .net

Answer 1

I resolved the problem. the cause was that i installed

• aspnetcore-runtime-2.1.0-preview1-final-win-x64 and
• .net core SDK 2.1.4-x64 versions.
• The installation placed the sdk files in c:\Program Files\dotnet
• but VS2017 32bit was looking for the sdk files in c:\Program Files(x86)\dotnet.

To resolve this i

• installed the x86 version of the sdk and aspnetcore runtime,

• set the MSBuildSDKsPath environmental variable to point to the new installation path.

• deleted all obsolete sdks from control panel

The question VS2017 Update 3 'Microsoft.NET.Sdk.Web' could not be found helped in resolving this issue.
