nuget update still fails for new csproj format

[nietras]

When will this be resolved? What if one needs to use the PackageReference and cannot use packages.config?

Details about Problem

Running:

nuget.exe update NewCsproj.csproj

fails with

Unable to update. The project does not contain a packages.config file.

NuGet Version: 4.4.1.4656
VS version (if appropriate): 15.5.2
MSBuild version: 15.5.180.51428 for .NET Framework
OS version (i.e. win10 v1607 (14393.321)): win10

Detailed repro steps so we can see the same problem

1. Run nuget.exe update on any new csproj file with PackageReference e.g.:

  <ItemGroup>
    <PackageReference Include="SomeNugetPackage" Version="1..0.0-alpha" />
  </ItemGroup>

Could you try donet Cli: https://github.com/dotnet/cli ? "donet add [csproj] package [packageName]", it should update the package for PackageReference.

Hi, I have two classic .csproj projects that use PackageReference both do not have packages.config file on one of them nuget update works, on the other it fails with "Unable to update. The project does not contain a packages.config file."
When Nuget searches for packages.config file ?

@zhili1208 any updates on this? Here is the current behavior:

The command doesn't fail or give any warnings:

But if you go back into Visual Studio it's clear that certain projects were completely skipped and are still referencing the old version of the component:

NuGet.exe commands like install or update aren't supported for PackageReference based projects. They are only supported for packages.config based projects. Instead please use dotnet add to add or update packages for PackageReference for now. And we also have a open workitem #4103 to explicitly support dotnet update command. So you can upvote on that existing issue.

dotnet add NewCsproj.csproj package SomeNugetPackage

does not update. If say 1.2.4 is installed, and a 1.2.5 is available then this command will not update to 1.2.5. If however I write:

dotnet add NewCsproj.csproj package SomeNugetPackage -v 1.2.5

It will change to 1.2.5. But I can't do that in my scenario, I need to update to latest version.

What you can do then is to remove and then update:

dotnet remove NewCsproj.csproj package SomeNugetPackage
dotnet add NewCsproj.csproj package SomeNugetPackage
