Unsafe code in a web site project

This may not be a best practice, but I have an issue in which ReSharper is
claiming all unsafe code in a web page is in error. I think this is fairly
easy to reproduce:

Create a web site (not a web application) and in the Default.aspx, add
CompilerOptions="/unsafe" to the Page header. The resulting page should be
something like this:

<%@ Page Language="c#" CompilerOptions="/unsafe" ..." %>

In the *.aspx.cs code behind file, add an unsafe method:

public unsafe void DoSomething()
{
    int* x;
}

The code compiles and runs even though ReSharper flags all occurrences of
the unsafe keyword and and all pointers.
