Scripts breaking after upgrade to .NET 7 due to missing classes from System.Security.Cryptography

[brandedoutcast]

Describe the bug

Both fsharp & csharp scripts fail to see any class from System.Security.Cryptography on .NET 7

To Reproduce

Running this code in an fsx file results in error FS0039: The value, namespace, type or module 'HMACSHA1' is not defined. Maybe you want one of the following: hash

open System.Text
open System.Security.Cryptography

let key = Encoding.Default.GetBytes("key")
let source = Encoding.Default.GetBytes("source")
HMACSHA1.HashData(key, source) |> printfn "hash %A"

A C# version of this code in a .csx file results in 'HMACSHA1' does not contain a definition for 'HashData'

Exceptions (if any)

error FS0039: The value, namespace, type or module 'HMACSHA1' is not defined. Maybe you want one of the following: hash

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@KevinRansom I don't appear to have permissions to transfer this to the fsharp repo. Can you take a look and see if you can?

[nagilson]

Deleted that comment as its copied in the F# one. But this is specifically talking about C#, the other issue is just F#.

[marcpopMSFT]

Moving this one over to roslyn. Could go to csharp interactive. There's a separate issue tracking the Fsharp behavior.

I had the same bug for MD5 in my fsx script , side stepped the problem by importing arbitrary wrapper nuget over the original MD5 implemenation:

#r "nuget: CryptHash.Net, 3.6.1"
