PixelBitmapContent<Vector4>.Copy works in XNA, but MonoGame throws exception

The following code works in XNA but MonoGame throws an exception:

System.InvalidOperationException: Could not copy between Vector4 and Vector4

PixelBitmapContent<Vector4> source, output;`


PixelBitmapContent<Vector4>.Copy(source, new Rectangle(0, 0, w, h),
                                           output, new Rectangle(x + 1, y + 1, w, h));

This is the framework code that throws the exception:

/// <summary>
        /// Copies one bitmap into another.
        /// The destination bitmap can be in any format and size. If the destination is larger or smaller, the source bitmap is scaled accordingly.
        /// </summary>
        /// <param name="sourceBitmap">BitmapContent being copied.</param>
        /// <param name="sourceRegion">Region of sourceBitmap.</param>
        /// <param name="destinationBitmap">BitmapContent being overwritten.</param>
        /// <param name="destinationRegion">Region of bitmap to be overwritten.</param>
        public static void Copy(BitmapContent sourceBitmap, Rectangle sourceRegion, BitmapContent destinationBitmap, Rectangle destinationRegion)
            ValidateCopyArguments(sourceBitmap, sourceRegion, destinationBitmap, destinationRegion);

            SurfaceFormat sourceFormat;
            if (!sourceBitmap.TryGetFormat(out sourceFormat))
                throw new InvalidOperationException("Could not retrieve surface format of source bitmap");
            SurfaceFormat destinationFormat;
            if (!destinationBitmap.TryGetFormat(out destinationFormat))
                throw new InvalidOperationException("Could not retrieve surface format of destination bitmap");

            // If the formats are the same and the regions are the full bounds of the bitmaps and they are the same size, do a simpler copy
            if (sourceFormat == destinationFormat && sourceRegion == destinationRegion
                && sourceRegion == new Rectangle(0, 0, sourceBitmap.Width, sourceBitmap.Height)
                && destinationRegion == new Rectangle(0, 0, destinationBitmap.Width, destinationBitmap.Height))

            // The basic process is
            // 1. Copy from source bitmap region to a new PixelBitmapContent<Vector4> using sourceBitmap.TryCopyTo()
            // 2. If source and destination regions are a different size, resize Vector4 version
            // 3. Copy from Vector4 to destination region using destinationBitmap.TryCopyFrom()

            // Copy from the source to the intermediate Vector4 format
            var intermediate = new PixelBitmapContent<Vector4>(sourceRegion.Width, sourceRegion.Height);
            var intermediateRegion = new Rectangle(0, 0, intermediate.Width, intermediate.Height);
            if (sourceBitmap.TryCopyTo(intermediate, sourceRegion, intermediateRegion))
                // Resize the intermediate if required
                if (intermediate.Width != destinationRegion.Width || intermediate.Height != destinationRegion.Height)
                    intermediate = intermediate.Resize(destinationRegion.Width, destinationRegion.Height) as PixelBitmapContent<Vector4>;
                // Copy from the intermediate to the destination
                if (destinationBitmap.TryCopyFrom(intermediate, new Rectangle(0, 0, intermediate.Width, intermediate.Height), destinationRegion))

            // If we got here, one of the above steps didn't work
            throw new InvalidOperationException("Could not copy between " + sourceFormat + " and " + destinationFormat);
