Can't upgrade packages.config file in VB.Net projects

[zifr]

Installed product versions

• Visual Studio: 2017 Enterprise
• This extension: 1.0.1

Description

In a .sln file, I have a couple VB.Net projects (of type Class Library). Each references one or more NuGet packages, and under each project root is the packages.config file. The tool fails to upgrade any of the packages.config files. I've ~~attached~~ pasted the contents of one of the packages.config that the tool was failing on.

Steps to recreate

1. Open solution containing several VB.Net projects.
2. In the solution explorer, click on one of the projects
3. On the toolbar click Project > Show all files
4. Back in the solution explorer, find the packages.config under the project we clicked in step 2.
5. Right click on "packages.config" > Upgrade to PackageReferences

Current behavior

In the output pane, the tool logs that the current packages.config was backed up then, on the very next step, it outputs that a null reference exception occurred. Pasted below is the full output.

Output

1/18/2018 18:16:31: Backup created for C:\[redacted]\packages.config.
1/18/2018 18:16:31: Update failed. Exceptions:

packages.config

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Microsoft.Azure.KeyVault.Core" version="2.0.4" targetFramework="net47" />
  <package id="Microsoft.Data.Edm" version="5.8.2" targetFramework="net47" />

  <package id="System.Spatial" version="5.8.2" targetFramework="net47" />
  <package id="WindowsAzure.Storage" version="8.0.1" targetFramework="net47" />
</packages>

Expected behavior

Convert the items within the packages.config file to PackageReferences within the .vbproj file.

I get the same error.

@robertmclaws could this please be fixed as this could be such a useful tool?

Same. Visual Studio 2017 Enterprise v15.7.4. @robertmclaws

Would be estatic to beta test.

Did they ever get around to fixing this?

[pcleckler]

Visual Studio 2017 has a conversion feature, so I doubt this will ever be fixed.

Right click a project with packages.config and the option will appear.
