.NET core 2.1 Custom Nuget package. Problem with missing *.runtimeconfig.json file in the project where the package was installed

Question

I have a console app project (.net core 2.1) which is my "custom package". The output of the package is the * .dll file.

I have installed my own package on different projects.

after

dotnet publish

I see that *.dll (from the package) file in the publish folder.

When I am trying to run this dll. I have an error like this:

Cannot use file stream for [D:\Daily\Daily*.deps.json]: No such file or directory A fatal error was encountered. The library 'hostpolicy.dll' required to execute the application was not found in 'D:\Daily\Daily'. Failed to run as a self-contained app. - The application was run as a self-contained app because 'D:\Daily\Daily*.runtimeconfig.json' was not found. - If this should be a framework-dependent app, add the 'D:\Daily\Daily*.runtimeconfig.json' file and specify the appropriate framework.

I spend some time to search a solution for my case but I can not fix it with possible solutions which I found.

When I did

dotnet publish

on the Package Project in outputs I see all what I need.

Problems occurs when package is installed in different project.

I tried to use

<PropertyGroup>
    <CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
</PropertyGroup>

<RestoreProjectStyle>PackageReference</RestoreProjectStyle>

My nuspec file below:

I had a similar problem. This is how i solved it.

I created a ProjectName.targets file in the project generating nuget package. Snapshot of nupkg

Included this property in the project using this nuget package

<CopyLocalLockFileAssemblies>true</CopyLocalLockFileAssemblies>
