Description Alexander Köplinger 2015-04-01 14:05:57 UTC
The following code generates an error when compiled with mcs:

> using System.Runtime.InteropServices;

> public class Test
> {
>     public void Foo(
>     [Optional, DefaultParameterValue(1)]
>     dynamic i)
>     {
>     }
> }

> test.cs(6,38): error CS1908: The type of the default value should match the type of the parameter
> Compilation failed: 1 error(s), 0 warnings

Note: this was extracted from the dynamics testsuite over at dotnet/corefx
