, and out
to appear more than one time in a parameter definition.
Example
The following example generates CS1107:
// cs1107.cs
public static class Test
{
// Extension methods.
public static void TestMethod(this this int t) { } // CS1107
}
public class TestTwo
{
// Regular Instance Method
public void TestMethod(ref ref int i) { } // CS1107
// Regular Instance Method
public void TestMethod(in in double d) { } // CS1107
}
