Invalid entry in NuGet [Content_Types].xml

[jorgeyanesdiez]

Product versions

• NuGet for BundlerMinifier.Core 2.6.362 (EDIT: or 2.7.385)(https://www.nuget.org/packages/BundlerMinifier.Core/2.6.362).
• Any of the following:
  • NuGet Server 3.0.0 (https://www.nuget.org/packages/NuGet.Server/3.0.0)
  • NuGet Server 2.14.1 (https://www.nuget.org/packages/NuGet.Server/2.14.1)
    EDIT: NuGet package explorer does not fail anymore, so I have removed it from this list. I will check newer versions of NuGet server soon too, but maybe this whole issue is now unecessary.

Description

The [Content_Types].xml file in bundlerminifier.core.2.6.362.nupkg contains the line:
<Override PartName="//prefercliruntime" ContentType="application/octet" />
which causes mentioned NuGet products to fail. The error states that a part uri cannot start with two forward slashes.

Steps to recreate

1. Install NuGet Server: (Instructions: https://docs.microsoft.com/en-us/nuget/hosting-packages/nuget-server)

2. Try to publish bundlerminifier.core.2.6.362.nupkg, you will get an error.

Current behavior

The NuGet file is incompatible (presumably invalid).
Screenshot here

Expected behavior

It should work.

Workaround

I have unpacked the nuget file and removed the line, and it works!

Assumed cause

I believe the problem is line 20 at:
BundlerMinifier.Core.csproj

<Content Include="prefercliruntime" Pack="true" PackagePath="\prefercliruntime" />

Maybe the PackagePath needs to be "prefercliruntime" (without the trailing slash?)
Maybe "/prefercliruntime" with a forward slash?
Is this line even needed at all anymore?

Is there any update on this issue.

Any updates on this, the issues is also there with : microsoft.visualstudio.web.codegeneration.tools.2.0.4
[Content_Types].xml :

<?xml version="1.0" encoding="utf-8"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
  <Default Extension="rels" ContentType="application/vnd.openxmlformats-package.relationships+xml" />

  <Default Extension="targets" ContentType="application/octet" />
  <Default Extension="nuspec" ContentType="application/octet" />
  <Override PartName="//prefercliruntime" ContentType="application/octet" />
</Types>

This is the culprit with double slash '//': <Override PartName="//prefercliruntime" ContentType="application/octet" />
