Unable to resolve 'Microsoft.NETCore.App (>= 2.1.0)' for '.NETCoreApp,Version=v2.1'

I am trying to resolve nugget packages with dotnet restore, but am getting the following error:

Unable to resolve 'Microsoft.NETCore.App (>= 2.1.0)' for '.NETCoreApp,Version=v2.1'

Here's my .csproj file

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Autofac" Version="4.5.0" />

    <PackageReference Include="BCrypt.Net-Core" Version="1.4.0" />
    <PackageReference Include="Easy.MessageHub" Version="3.2.1" />

  </ItemGroup>

  <Target Name="ApplyXdtConfigTransform" BeforeTargets="_TransformWebConfig">
    <PropertyGroup>
      <_SourceWebConfig>$(MSBuildThisFileDirectory)Web.config</_SourceWebConfig>
      <_XdtTransform>$(MSBuildThisFileDirectory)Web.$(Configuration).config</_XdtTransform>
      <_TargetWebConfig>$(PublishDir)Web.config</_TargetWebConfig>
    </PropertyGroup>
    <Exec Command="dotnet transform-xdt --xml &quot;$(_SourceWebConfig)&quot; --transform &quot;$(_XdtTransform)&quot; --output &quot;$(_TargetWebConfig)&quot;" Condition="Exists('$(_XdtTransform)')" />
  </Target>
</Project>

I have installed dotnet-sdk-2.1.300-rc1-008673-win-x64 and I am using Visual Studio 2017 v15.2

You can add the v3 nuget source via the dotnet cli:

dotnet nuget add source --name nuget.org https://api.nuget.org/v3/index.json

If that doesn't work, try running clearing out the local cache:

dotnet nuget locals all --clear
dotnet restore --force

Update your nuget.config file located in:

C:\Users\{username}\AppData\Roaming\NuGet\nuget.config

You need to add the v3 endpoint like this:

<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />   
    </packageSources>

Problem was Visual Studio version.

Solution was to create MSBuildSdksPath environment variable that is pointing to dotnet\sdk{{version}}\Sdks, like on the following link https://github.com/aspnet/Announcements/issues/231
