[Bug] Unable to upload .nupkg file with schema version 1.0.0

[ZaneJo]

Workload Manifest Schema Version

1.0.0

Description

I am trying to upload and publish the NuGet package for my workload, but am getting an error notification saying "Please ensure you upload a valid .nupkg package file". This worked on March 9th, and did not work on March 16th. The only difference between the two uploads is the workload version in the WorkloadManifest.xml.

I tried running the validator from this repo, but it fails when trying to download the ItemDefinition.xsd with schema version 1.0.0.

Steps to Reproduce

1. Set the schema version in the src/packages/manifest/Item1.xml and src/packages/manifest/WorkloadManifest.xml to 1.0.0.
2. Build the backend project.
3. In Fabric, attempt to upload a new version of the workload, choosing the .nupkg file from the bin corresponding to the build configuration you used.

Expected vs Actual Behavior

Expected: The new version of the workload should be uploaded.
Actual: The new version of the workload is not uploaded. Instead, a notification toast displays the following error: "Please ensure you upload a valid .nupkg package file".

Hi, this error occurs when you try to upload a file that is not a .nupkg file.
Please make sure that the extension name of the file is .nupkg.
If you're on windows make sure that 'show file name extensions' is checked -

And make sure that the type says "NuGet package file"
