Support for FSharp 4.3.1

[JohnDoeKyrgyz]

I am trying to git deploy an ASP.NET MVC website where all the controllers and business logic are written in F#. I am using the latest version of F# (4.3.1) unfortunately it does not look like this version is supported. Here is the deploy log:

I can successfully deploy this site using the publish feature from visual studio, but I have to add a reference to FSharp.Core to the web project, and set Copy Local to true.

Would you be able to share a sample repo that demonstrates the issue (e.g. on GitHub)?

For reference, this is the test repo we use, which works in Azure Web Sites: https://github.com/KuduApps/WebAppWithFSharpLibrary.

If you look in D:\Program Files (x86)\Reference Assemblies\Microsoft\FSharp\.NETFramework\v4.0\4.3.1.0 on the Azure Web Sites machine (using Kudu Console), it looks like this version is present, so I'm not sure why it's not working.

Hello David,

Thanks for looking into this. I have a sample repo at:

https://github.com/JohnDoeKyrgyz/AzureTest

Thanks,

Yes, it does look like an issue on our side. I wonder if you could workaround by using a hint path going to where the assembly is (path above).

Hello David,

Tried to set the HintPath, and I am still getting deploy errors

F# 3.1 should work on Azure now. Feel free to reopen if there are more issues.
