  It is to your advantage to use the type-specific implementation of the <xref:System.Collections.Generic.List%601> class instead of using the <xref:System.Collections.ArrayList> class or writing a strongly typed wrapper collection yourself. The reason is your implementation must do what the .NET Framework does for you already, and the common language runtime can share Microsoft intermediate language code and metadata, which your implementation cannot.  
   
 ## F# Considerations  
- The <xref:System.Collections.Generic.List%601> class is used infrequently in F# code. Instead, [Lists](/dotnet/fsharp/language-reference/lists), which are immutable, singly-linked lists, are typically preferred. An F# List provides an ordered, immutable series of values, and is supported for use in functional-style development. When used from F#, the <xref:System.Collections.Generic.List%601> class is typically referred to by the [ResizeArray\<'T>](https://fsharp.github.io/fsharp-core-docs/reference/fsharp-collections-resizearray-1.html) type abbreviation to avoid naming conflicts with F# Lists.

 ## Examples  
  The following code examples show the Web.config file for an ASP.NET application configured to use an <xref:System.Web.Security.ActiveDirectoryMembershipProvider> instance. The first example uses the default mappings for Active Directory attributes, and does not support password-reset security with question-and-answer nor the ability to call search methods. The second example shows all the attribute settings allowed for an <xref:System.Web.Security.ActiveDirectoryMembershipProvider> instance.

  The following example displays the strings returned by calling the <xref:System.TimeSpan.ToString%2A> method with a number of <xref:System.TimeSpan> values. Note that although the example does not call the <xref:System.TimeSpan.ToString%2A> method directly, it is called by the <xref:System.Console.WriteLine%2A?displayProperty=nameWithType> method when it attempts to convert a <xref:System.TimeSpan> value to its string representation.
