Core: error: Project <name> does not have a lock file

[sravan1022]

I am new to the .NET core and working on the TodoApi tutorial but in the middle i found the error that "project TodoApi does not have a lock file". Anyone help me to resolve this.

run dotnet restore on your project.

In my case that makes no difference whatsoever

C:\Users\Bruce\Desktop>md test

C:\Users\Bruce\Desktop>cd test

C:\Users\Bruce\Desktop\test>dotnet new

And the project.json says

  },

    "netcoreapp1.0": {
      "imports": "dnxcore50"
    }
  }
}

Not happy

@axtens I think that means you have the directory C:\Users\Bruce\Documents\Projects\Work\Resources\packages configured as package source in your C:\Users\Bruce\AppData\Roaming\NuGet\NuGet.Config, but that directory does not exist.

Either remove or disable that source (by manually editing NuGet.Config or from VS) or create that directory.

@livarcocc I think the error message should be describe solution (explicit or with link)

"project TodoApi does not have a lock file. Please run "dotnet restore" or see http://link-to.solution"

Need to google it to find the right solution :smile:
