Description Alexander Köplinger 2015-08-16 14:20:51 UTC
Take the following code:

> public class Test
> {
> 	public static void Main()
> 	{
>		new float();
>	}

Compile it:

> $ mcs test.cs 
> test.cs(5,3): error CS0201: Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement

It compiles fine with MS csc.exe. This was found in one of the dotnet/coreclr test cases, not sure how relevant it is in real code given that it's basically a nop.
