System.MissingMethodException

Hi,

I keep getting this error when I try to run the scripts.
depending on which script, it's a different method being referenced.

I think it has something to do with my F# tools, but seeing as this is my first experience using F#, I have no clue how to resolve this.

Below 2 of the exceptions I'm getting

SolutionExportDev.fsx / CountEntities.fsx

System.MissingMethodException: Method not found: 'Microsoft.FSharp.Core.FSharpOption`1<!!0> Microsoft.FSharp.Collections.SeqModule.TryHead(System.Collections.Generic.IEnumerable`1<!!0>)'.

It seems you are running an old version of F# (I interpret it as being version 3). DAXIF requires F# v4.

How are you executing the scripts? I recommend enabling F#-support in Visual Studio 2017, and then using Execute In Interactive (Alt+Enter) directly from the scripts in Visual Studio. The F# Setup-page on the wiki has been updated accordingly.

thank you for the quick reply.
when i run it from vs2017 I get a different error
PluginSyncDev.fsx(14,1): error FS0039: The value, namespace, type or module 'Plugin' is not defined.

Am I still forgetting something?

You need to select the lines you want to execute when using Execute In Interactive (Alt+Enter). I am guessing that you have only selected the last line now.

Could you try Ctrl+A in your script before executing?

now i feel like an idiot :-)
thank you for the help!
