MissingMethodException when using FSharp.Data in a PCL

[tgnm]

Not sure why I keep getting this exception:

Result Message: System.MissingMethodException : Method not found:
 'Microsoft.FSharp.Control.FSharpAsync`1<System.IO.TextReader> FSharp.Data.Runtime.IO.asyncReadTextAtRuntime(System.Boolean, System.String, System.String, System.String, System.String)'.

I have tried different FSharp.Core binding redirects and I still have issues.

The PCL profile I am using is 47 (new Portable library in VS 2013).

I am not entirely sure but it seems to be related to this issue: #398

I have also posted a question on SO: http://stackoverflow.com/questions/23389752/missingmethodexception-when-running-a-unit-test-that-uses-fsharp-data

47 is the legacy profile, the new one is 7. Don't use 7, I have removed it from the latest nuget package because it was not working properly

@ovatsus thanks! That was indeed what was causing the issue.

@ovatsus I'd like to help take another look at getting Profile 7 to work at some point

[ovatsus]

I've removed it form the package, but I still left all the issues and the code fixes for it in the source code. In any case, it's good to be able to have a PCL7 library in general, but I'm starting to think there's no real benefit on getting a PCL7 version of FSharp.Data, as you can reference PCL47 from a PCL7 library, if you need it

I'm seeing the exact same thing on netcoreapp5.0. I assume it's a problem with the .NET 5 SDK preview?

I noticed the same in FAKE build script referencing FSharp.Data. I have no .NET 5 preview installed.

".fake/fake.exe" --version
FAKE 5 - F# Make (5.20.0)
FakePath: .......fake.store\fake-cli\5.20.0\fake-cli\5.20.0\tools\netcoreapp2.1\any\Fake.Runtime.dll
Paket.Core: 5.245.1

dotnet --version
3.1.201

@OlegZee Same, don't have .NET 5 and still get this error.
