When I try to publish my application to the web server after upgrading to .NET Core 2.1 from 2.0, I get this message: "This version of Microsoft.AspNetCore.All is only compatible with the netcoreapp2.1 target framework. Please target netcoreapp2.1 or choose a version of Microsoft.AspNetCore.All compatible with netcoreapp2.0."

It runs fine on my development machine.

Here is my project file:

<Project Sdk="Microsoft.NET.Sdk.Web">
<PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <RunPostBuildEvent>Always</RunPostBuildEvent>
</PropertyGroup>
<ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.1.0" />
    <PackageReference Include="Microsoft.AspNetCore.Cors" Version="2.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="2.1.0" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.1.0" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.1.0" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Tools" Version="2.0.4" />
</ItemGroup>
</Project>

I have seen this, but it does not seem to be the problem. I have also experimented with the prerelease 2.1 version of CodeGeneration.Tools, but I was not able to install it.

EDIT: I did install dotnet 2.1 on the server.

Here's what I see on the server:

D:\>dotnet --info
Host (useful for support):
  Version: 2.1.0

I had the same problem, but then I had not updated the publish profile file(.pubxml) for the right targetenvironment

< TargetFramework>netcoreapp2.1< /TargetFramework>

And regarding to earlier answer the row 

< DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.1" />

Show be removed in 2.1 version beacuse of obsolete and are included nowaday
