Assets file project.assets.json not found. Run a NuGet package restore

Question

I\'m trying to use nopCommerce(Which is written in .NET Core) but when I want to run the project I face 52 Errors telling me Run a nuget package restore

Answer 1

I lost several hours on this error in Azure DevOps when I set the 'Visual Studio Build' task in a build pipeline to build an individual project in my solution, rather than the whole solution.

Doing that means that DevOps either doesn't build any (or possibly some, I'm not sure which) of the projects referenced by the project you've targeted for the build, and therefore those projects won't have their project.json.asset files generated, which then causes this issue.

The solution for me was to swap from using the VS Build task to the MSBuild task. Using the MSBuild task for an individual project correctly builds any projects referenced by the project you're building and eliminates this error.
