Take the following steps to include OpenSilver private package in delivery (offline).

• Create Nuget.Config file in the solution folder with the following content.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <solution>
    <add key="disableSourceControlIntegration" value="true" />
    <add key="dependencyversion" value="Highest" />
  </solution>

  <packageSources>
    <add key="PrivatePackages" value="PrivatePackages" />
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>

• Create a new folder named PrivatePackages in the solution folder.
• Create OpenSilver package following the instructions here.
  • Use build-nuget-package-OpenSilver-private.bat and follow this naming convention: OpenSilver.1.0.0-private-YYYY-MM-DD.nupkg where you should replace YYYY, MM and DD with today's date.
• Install nuget package inside PrivatePackages.

nuget.exe add output\OpenSilver\OpenSilver.1.0.0-private-<version>.nupkg -source <Project_Path>\PrivatePackages\

• Reference the package.

After Nuget.Config creation "Package source" will have one more option - "PrivatePackages".

If the option is selected then OpenSilver will appear in Browse tab. Make sure 'Include prerelease' is checked.

• Change .gitignore to be able to push to git.

REPLACE:

*.nupkg

WITH:

.nupkg !PrivatePackages/.nupkg
