I found some bugs in the newest Mono for Android Beta.

1. The "BinaryWriter.Dispose()" method is private. This should be an easy fix.

2. An IntPtr can't be added with an int or other IntPtr (operator+(), etc.)

Kind Regards

First of all, our core libraries for mobile are mostly based on CoreCLR-based (Silverlight's) class library profile. So they are generally compared to Silverlight. Then...

1. While it is possible to make a change, this is not a bug. BinaryWriter.Dispose() is public only after Slverlight version 4 or .NET 4.0 and our mobile codebase is largely from Silverlight 3.5 era. The "private" BinaryWriter.Dispose() is rather an explicit interface implementation which means the type works as IDisposable (otherwise our class library itself does not build).

2. IntPtr.Addition operator is not available in Silverlight profile either. It is available only in .NET 4.0 or later. We may move forward to change some build profiles in the future, but not right now.
