Details:

The method 'byte[] ReadBytes(int count)' of System.IO.BinaryReader doesn't
read the specified amount of bytes although the end of the stream isn't
reached.

In MS.NET there is a while loop to read the specified amount of bytes until
the end of the stream is reached.

For DotGNU the method should look like this:
public virtual byte[] ReadBytes(int count)
{
        byte[] buffer;
        int result;
        if(count < 0)
        {
                throw new ArgumentOutOfRangeException("count", 
"ArgRange_NonNegative"));
        }
        buffer = new byte [count];
        
        do
        {
                int num2 = Read(buffer, result, count);
                if (num2 == 0)
                {
                        break;
                }
                result += num2;
                count -= num2;
        }
        while (count > 0);

        if (result != buffer.Length)
        {
                byte[] newBuffer = new byte [result];
                Array.Copy(buffer, newBuffer, result);
                return newBuffer;
        }
        else
        {
                return buffer;
        }
}
