Register new Plugin is always failing with dependency issue

[SweetsNSavories]

I am trying to register a new XrmToolBox plugin from NuGet:

Package ID: VerseOps.XrmToolBox
Current NuGet version: 1.0.16.1
Package URL: https://www.nuget.org/packages/VerseOps.XrmToolBox/1.0.16.1
Registration page: https://www.xrmtoolbox.com/plugins/new/

The portal rejects it with:

"Errors have been found in your Nuget package: XrmToolBox version dependency is missing in Nuget package."

I believe the dependency marker is present in the current NuGet package. NuGet registration metadata for 1.0.16.1 shows:

dependency id="XrmToolBox"
range="[1.2025.10.74, )"

The nupkg layout is:

lib/net48/Plugins/VerseOps.XrmToolBox.dll
lib/net48/Plugins/VerseOps.XrmToolBox/VerseOps.Api.Core.dll
lib/net48/Plugins/VerseOps.XrmToolBox/Microsoft.Identity.Client.dll
lib/net48/Plugins/VerseOps.XrmToolBox/Microsoft.Identity.Client.Extensions.Msal.dll
lib/net48/Plugins/VerseOps.XrmToolBox/Microsoft.IdentityModel.Abstractions.dll

The package also has:

• icon URL
• project URL
• XrmToolBox tag
• plugin assembly version matching NuGet package version: 1.0.16.1
• exported SmallImageBase64 and BigImageBase64 metadata
• INoConnectionRequired implemented on the plugin control

The registration POST returns HTTP 200 with the validation error in the returned HTML. My HAR does not show any browser-side calls to NuGet, so I assume the portal validates NuGet server-side.

Could the portal validator be using stale NuGet metadata/cache, or is there another package-layout/dependency format it expects for multi-DLL tools?

The plugin registration process analyze ALL listed version. So, I guess your first versions do not have this dependency marker. Just unlist versions that don't have this marker from nuget portal and you should be good
