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

Cause of this defect: you have to remove the injected Nuget in file explorer. Solution: Once you remove that Nuget in your system, then remove from following location. select Tool=>Options=>NuGet Package Manager=> Package Sources then uncheck Microsoft Visual Studio Offline Packages Option

Answer 2

When using VSTS, check your global.json file. I had entered the sdk version as just "2.2" which caused a parse error (but not when building locally). Adding the full version, "2.2.104" solved the problem.

Answer 3

This worked for me: added this package source: Microsoft and .net https://www.nuget.org/api/v2/curated-feeds/microsoftdotnet/ then run "dotnet restore" in the console

Answer 4

To fix this error from Tools > NuGet Package Manager > Package Manager Console simply run:

dotnet restore

The error occurs because the dotnet cli does not create the all of the required files initially. Doing dotnet restore adds the required files.

Answer 5

If simply restoring NuGet packages does not work make sure in Tools -> Options -> NuGet Package Manager -> General under Package Restore that the "Allow NuGet to download missing packages" is checked.

Then Restore NuGet Packages again OR just REBUILD after deleting obj and bin folders.

Answer 6

For me I upgraded NuGet.exe from 3.4 to 4.9 because 3.4 doesn't understand how to restore packages for .NET Core.
