System.Web.Securit.Membership, GetUser throws a System.UnauthorizedAccessException

Question

I have a new Visual Studio 2015 FSharp project (.NET Framework 4.6 / FSharp Core 4.4). I added a script file and code as follows:

#r "System.Web.ApplicationServices.dll"

open System.Web
open System.Web.Security

let userName = "Jamie"
let user = Membership.GetUser(userName)

When I run it, I get:

System.UnauthorizedAccessException: Access to the path "C: \ Program Files (x86) \ Microsoft SDKs \ F # \ 4.0 \ Framework \ v4.0 \ App_Data" is denied. in System.IO .__ Error.WinIOError (Int32 errorCode, String maybeFullPath) in System.IO.Directory.InternalCreateDirectory (String fullPath, String path, Object dirSecurityObj, Boolean checkHost) in System.IO.Directory.InternalCreateDirectoryHelper (String path, Boolean checkHost) in System.IO.Directory.CreateDirectory (String path) in System.Web.DataAccess.SqlConnectionHelper.CreateMdfFile (String fullFileName, String dataDir, String connectionString) in System.Web.DataAccess.SqlConnectionHelper.EnsureDBFile (System connectionString) .Web.DataAccess.SqlConnectionHelper.GetConnection (String connectionString, Boolean revertImpersonation) in System.Web.Security.SqlMembershipProvider.GetUser (username, Boolean userIsOnline String) in System.Web.Security.Membership.GetUser (username, Boolean userIsOnline),
