Publishing F# function from command line tool doesn't work.

Good morning,

The problem: I have a precompiled F# project. I can't run `func azure functionapp publish mywebappname` on the F# project. It returns the following error running on any folder of the project (root folder, publish folder, bin folder, fsproj folder, etc.)

Can't determin Project to build. Expected 1 .csproj but found 0

The workaround: I can navigate to inside VS Code:

\bin\Debug\netcoreapp2.0\publish

Then, I can right-click and select "Deploy to Function App". This is an Azure Functions Extensions to VS Code that works fine.


I'm using Azure Functions V2. My dotnet --info is:

Start with the `func azure functionapp publish` command and reproduce the failure using the precompiled F# project and its root, publish, bin, and fsproj directories. Compare the command-line behavior with the VS Code "Deploy to Function App" workflow; done means an Azure Functions V2 F# project can be published without requiring a `.csproj` file.
