the runcommand property is not defined on ASP.NET Core 2

Question

In Visual Studio 2017, I got an error in all projects that are related with ASP.NET Core 2 . That says:

unable to run your project. the runcommand property is not defined

Even I uninstalled the VS and again installed it but I have still this problem. I tested default project template for VS but those do not execute right, too. Please help me.

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

  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <DockerComposeProjectPath>..\docker-compose.dcproj</DockerComposeProjectPath>
    <ApplicationIcon />
    <OutputType>Library</OutputType>
    <StartupObject />
  </PropertyGroup>

  <ItemGroup>
    <Folder Include="Views\Product\" />
    <Folder Include="wwwroot\" />
  </ItemGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.All" Version="2.0.3" />
    <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="2.0.1" />
    <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.0" />
  </ItemGroup>

</Project>
