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

To those with the same issue as me in Azure DevOps / VSTS environment encountering a similar message: C:\Program Files\dotnet\sdk\2.2.104\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets(208,5): Error NETSDK1004: Assets file '...\obj\project.assets.json' not found. Run a NuGet package restore to generate this file

Add /t:Restore to your MSBuild Arguments in Build Solution.

Answer 2

Nothing above worked for me. But simply deleting all 'bin' and 'obj' folders did the trick.

Answer 3

Seen this after adding a WinForms Core 3.1 project (from project templates) on VS-2019 vs 16.4.0 and trying to run it out of the box. Clean or Rebuild the entire solution did not work.

I just reloaded my solution.. that is File/Close Solution and then reopening it and rebuilding it solved the problem.

Answer 4

In case when 'dotnet restore' not works, following steps may help:

1. Visual Studio >> Tools >> Options >> Nuget Manager >> Package Sources
2. Unchecked any third party package sources.
3. Rebuild solution.

Answer 5

Try this (It worked for me):

• Run VS as Administrator
• Manual update NuGet to most recent version
• Delete all bin and obj files in the project.
• Restart VS
• Recompile

Answer 6

run your VS as administrator after that in package manager console run dotnet restore.
