System.MissingMethodException: method not found: 'FSharp.Data.HttpResponse

Question

I wrote ATs for my application in F # using Tickspec. I use FSharp.Data.Http.Requestand I get the following error:

System.MissingMethodException : Method not found: 'FSharp.Data.HttpResponse

FSharp.Data version 2.1.1.0.

In fsproj:

ToolsVersion is 14.0

TargetFrameworkVersion is v4.6.1

F# is 4.0.

I have a different AT set for another application, and I use the same method FSharp.Data.dlland the same one Http.Request, and they use F# 4.0, and I had no problems.

I don’t think there is a problem with dll, as I used it in the sample application and I was able to use this Http.Request method. I created a completely new solution, because, in my opinion, maybe I used the old version of FSharp.Core and still the same problem with FSharp.Data.

, , F#3.0 . F#3.0, , F#4.0 .

, ?
