F# compiler messages

This section details compiler errors and warnings that the F# compiler will emit for certain constructs. The default sets of errors can be changed by:

• Treating specific warnings as if they were errors by using the -warnaserror+ compiler option,

• Ignoring specific warnings by using the -nowarn compiler option

If a particular warning or error is not yet recorded in this section:

• Go to the end of this page and send feedback that includes the number or text of the error, or
• Add it yourself by following the instructions in create-new-fsharp-compiler-message.fsx and opening a pull request for this repository.
