I see a thread here https://pulumi-community.slack.com/archives/C019YSXN04B/p1619024754146000 about it but it looks like Ringo was using the pulumi service backend so he was able to just provide an access token

I don’t think so? I haven’t tried this in .NET, but in NodeJS, for example, I had no issues setting the backend via project settings (and don’t do anything with the env var)

Could it be that your backend URL is malformed? That could force the CLI to try and log you in to the service: https://github.com/pulumi/pulumi/blob/73a66f48ead301bacf1d7d2833c016cf803b57c1/pkg/cmd/pulumi/login.go#L128

I believe that was the issue. I was using local filestate for testing purposes and my path was

file://{path}

but when you use

Path.Combine(...)

in dotnet it uses back slashes instead of forward slashes, so pulumi wasn't liking that. Thanks guys!

@faint-table-42725 I've verified that it works in .NET.
