Could not load file or assembly 'TypeShape, Version=8.0.1.0'

Description

Retrieving the config fails with Could not load file or assembly 'TypeShape, Version=8.0.1.0,...

Repro steps

1. Create a new project referencing FsConfig
2. Create a config record type and use the default match expression from the docs to retrieve the config

Expected behavior

Config gets successfully retrieved.

Actual behavior

The following exception gets thrown:

Unhandled exception. System.IO.FileLoadException: Could not load file or assembly 'TypeShape, Version=8.0.1.0, Culture=neutral, PublicKeyToken=null'. The located assembly's manifest definition does not match the assembly reference. (0x80131040)
File name: 'TypeShape, Version=8.0.1.0, Culture=neutral, PublicKeyToken=null'
   at FsConfig.Core.parseInternal[T](IConfigReader configReader, FSharpFunc`2 fieldNameCanonicalizer, FieldValueParseArgs args)
   at Program.main(String[] argv) in

Known workarounds

Add TypeShape directly to the project:

    <PackageReference Include="TypeShape" Version="8.0.1" />

@tamizhvendan I’ve just published version 3.0.0. The problem looks solved now. Tested with the following Dockerfile:

FROM mcr.microsoft.com/dotnet/sdk:5.0.102-ca-patch-buster-slim
WORKDIR /app
RUN dotnet new console -lang f# && dotnet add package FsConfig && echo '\n\
open System \n\
open FsConfig\n\
[<EntryPoint>]\n\
let main argv =\n\
  EnvConfig.Get<string>() |> ignore\n\
  printfn "- OK -"\n\
  0' \
> Program.fs && dotnet run

It looks like I need some more time to troubleshoot this. I will get back to you this weekend.
