The automation api equivalent of the 
pulumi up
cli seems to be roughly: • var stack = LocalWorkspace.CreateOrSelectStackAsync • stack.Workspace.InstallPluginAsync • stack.SetAllConfigAsync • stack.RefreshAsync // needed? • stack.UpAsync Would the equivalent of the 
pulumi preview
cli be the following? (Not really in any examples?) • var stack = LocalWorkspace.CreateOrSelectStackAsync • stack.Workspace.InstallPluginAsync • stack.SetAllConfigAsync • stack.RefreshAsync // needed? • stack.PreviewAsync Are any of these steps not really needed like the refresh?

Hey @worried-city-86458 So Refresh is optional and at your discretion incase there are external changes - I usually run a refresh by habit as part of my workflow but I don't make changes outside of Pulumi - the preview steps look correct!

Not sure if I'm doing something wrong but I can't get preview to work:

That looks like a bug. Though I'm surprised you're seeing it when you aren't subscribing to the 
OnEngineEvent
delegate. Let me take a look

@worried-city-86458 mind sharing what version of automation API you're using? Are you by chance running on .NET 5?

Ha well I think I know what the issue is. If I'm right it will affect everyone that takes a dependency on 
Pulumi.Automation
that is targetting .NET 5

@bored-oyster-3147 Yes, I'm using dotnet 5.
Latest alpha of automation api

Thanks for confirmation. I made an issue for this here: https://github.com/pulumi/pulumi/issues/7047 I'm busy today but can either get to it later or tomorrow

Hope you don't mind @bored-oyster-3147, had some free time so went ahead and created https://github.com/pulumi/pulumi/pull/7051 to fix this

Might be worth bumping the dotnet sdk used to build to the latest (5.0.203)

We use 3.1 as that's the LTS atm @worried-city-86458

@broad-dog-22463 fair enough; although my understanding is you can / should use the latest dotnet sdk to build things, since it has the latest sdk related fixes etc, but can still target previous frameworks with it. Normally you'd still install multiple runtimes to make sure you test with the required target runtime, so for example you could install dotnet 3.1 (separately) and dotnet 5.0 (via sdk) runtimes. Then your tests could multi-target dotnet 3.1/5.0 and issues like the above would be flushed out for users of dotnet 5.0.

I agree with you @worried-city-86458 and I’m in the middle of some improvements here
