Publishing standalone app with a dot '.' in name on linux generates executable in an unexpected way

Steps to reproduce

• On Ubuntu 16.04 LTS, install the latest version of CLI (I had 5825)
• mkdir sample.webapi
• cd sample.webapi
• dotnet new webapi
• Open the .csproj file and add a runtime identifier for linux-x64 <RuntimeIdentifiers>linux-x64</RuntimeIdentifiers> and save the file
• Open the NuGet.config file and remove the dotnet-core feed as aspnetcore-dev would suffice here
• dotnet restore
• dotnet publish -r linux-x64

Expected behavior

The published output should have an executable with name sample.webapi

Actual behavior

An executable with name sample.webapi.webapi

Environment data

dotnet --info output:

@peterhuene any chance to get a fix into 2.2? It’s a bit sad that dotnet run doesn’t work when a RuntimeIdentifier is specified in the project file and there is a dot in the project name…

@fbarletta as a workaround, could you add this to the project and test if it works?:

  <Target Name="FixRidSpecificHost" AfterTargets="_ComputeNETCoreBuildOutputFiles">
    <ItemGroup>
      <None Remove="@(NativeAppHostNETCore)" />
      <None Include="@(NativeAppHostNETCore)" Link="$(AssemblyName)" CopyToOutputDirectory="PreserveNewest" CopyToPublishDirectory="Never"/>
    </ItemGroup>
  </Target>
