<@USVQLK3FA> what version of Pulumi are you using?

This feels like you are using a v2.0.0-beta build

Latest packages pulled by paket, so v2 and Azure v3. I'm working on getting the exact versions.

```pulumi plugin ls
NAME    KIND      VERSION                           SIZE    INSTALLED       LAST USED
azure   resource  3.1.0-alpha.1586251892+g61a25a08  172 MB  43 minutes ago  1 minute ago
azure   resource  3.0.0-beta.1                      172 MB  1 week ago      1 minute ago
azure   resource  2.4.0-alpha.1585596375+g39a541f3  172 MB  1 week ago      1 minute ago
random  resource  2.1.0-alpha.1586540537+gaac8346   38 MB   37 minutes ago  1 minute ago
random  resource  2.0.0-beta.2                      38 MB   1 week ago      1 minute ago```

```    Pulumi (2.0.0-beta.3)
    Pulumi.Aws (2.0.0-beta.2)
    Pulumi.Azure (3.1.0-alpha.1586251892)
    Pulumi.FSharp (2.0.0-beta.3)
    Pulumi.Gcp (3.0.0-preview-beta.1)
    Pulumi.Random (2.1.0-alpha.1586540537)```

yeah the v2 of pulumi and the providers (v3 of Azure and Gcp) have breaking changes

with respect to each other or the pulumi exe?

<https://github.com/pulumi/pulumi/blob/master/CHANGELOG.md>

you can see the Pulumi binary changes here

and your issue is listed on that unreleased list

Yes, we’ve recently changed that property. That’s like the last breaking change before shipping.

You either need to wait for the next beta of the providers, or use 1.x Pulumi nuget and 2.x Azure NuGet

Or probably Azure 3.0.0-beta.1 should be fine
