Hello. I have very similar issue while running the app on the remote hosting server. However all is OK on my machine while running with VS 2017 Community, F# 4.1, WebSharper 3.6.19.242, .NET 4.6
. According to the info specified by hosting provider, their server supports ASP.NET 4.0, .NET <=4.6.3
. How can I fix the problem?
P.S.: Here is a gist with stack trace in my case.
Hi,
this must be some problem with initializing the project by Visual Studio, it seems that some project reference is added multiple times and WebSharper 3 handled it wrong. Did the issue persist after reloading the project? (fixed in Zafir - WS4 beta)

I've created a new project using the template "UI.Next Client-Server Applicatin". On running from VS I get a server error (stack trace below).
Running VS2015, WebSharper 3.6.18.241.
Any idea how to get this working?
