The specified Microsoft.NETCore.App', version '2.0.7' was not found

cannot start .NET Core app because of this error:

"It was not possible to find any compatible framework version The specified framework 'Microsoft.NETCore.App', version '2.0.7' was not found. - Check application dependencies and target a framework version installed at: \ - Alternatively, install the framework version '2.0.7'. The program '[1560] dotnet.exe' has exited with code -2147450749 (0x80008083)."

Editing .csproj didn't help. It looks like this:

<PropertyGroup>
<TargetFramework>netcoreapp2.0</TargetFramework>
<RuntimeFrameworkVersion>2.0.7</RuntimeFrameworkVersion>
<DockerComposeProjectPath>..\docker-compose.dcproj</DockerComposeProjectPath>
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>

You don't have the right .NET Core runtime installed. It's not good enough that's a .NET Core 2 runtime; it needs to be a minor version that is equal to or encompasses the version you're trying to target. You can see all the available runtimes here: https://www.microsoft.com/net/download/all. Specifically, you need 2.0 Runtime (v2.0.7) or higher. You can just choose 2.1, though. 2.0.7 will be rolled in and then, if you do end up upgrading your project later, you won't run into this issue again.
