Unable to install azurenextgen plugin for Windows

[orteme]

Issue description

Staring today 10/16/2020 I am unable to install azurenextgen plugin anymore.
pulumi plugin install or pulumi plugin install resource azurenextgen 0.2.2 fails with error HTTP 403

>pulumi plugin install resource azurenextgen 0.2.2
[resource plugin azurenextgen-0.2.2] installing
error: [resource plugin azurenextgen-0.2.2] downloading from : 403 HTTP error fetching plugin from https://get.pulumi.com/releases/plugins/pulumi-resource-azurenextgen-v0.2.2-windows-amd64.tar.gz

The same behavior with other plugin versions:

• 0.2.1
• 0.2.0
• 0.1.0

Steps to reproduce

1. Install Pulumi CLI v2.12.0 for Windows
2. Run pulumi plugin install resource azurenextgen 0.2.2

Try pulumi plugin install resource azure-nextgen 0.2.2 (azure-nextgen with a dash)

I can replicate the behavior with:
$ pulumi plugin install
running 'dotnet build -nologo .'

temp3temp3 -> ../temp3/bin/Debug/netcoreapp3.1/temp3temp3.dll

When I run
$ pulumi plugin install resource azure-nextgen 0.2.2

@tusharshahrs Thanks for the repro, I can also see this now. It looks like our .NET plugin discovery is broken here.

@tusharshahrs can you also include the pulumi program you used to repro?

[tusharshahrs]

@jaxxstorm Here you go:

$ mkdir ~/temp/temp4
$ cd ~/temp/temp4
$ pulumi new azure-nextgen-csharp
~/temp/temp4 $ pulumi plugin install resource azure-nextgen 0.2.2
[resource plugin azure-nextgen-0.2.2] installing
tusharshah@Tushars-MBP ~/temp/temp4 $ pulumi plugin install
running 'dotnet build -nologo .'
Determining projects to restore...
All projects are up-to-date for restore.

temp4 -> ...temp/temp4/bin/Debug/netcoreapp3.1/temp4.dll

Build succeeded.

These are the files that are generated:
