The BitBlt function performs a bit-block transfer of the color data corresponding to a rectangle of pixels from the specified source device context into a destination device context.

''' <param name="nYDest">The topmost y-coordinate of the destination rectangle (in pixels).</param>

If a rotation or shear transformation is in effect in the source device context, BitBlt returns an error. If other transformations exist in the source device context (and a matching transformation is not in effect in the destination device context), the rectangle in the destination device context is stretched, compressed, or rotated, as necessary.

The unmanaged prototype contains a return directive because the CreateSymbolicLink API function returns BOOLEAN, a one-byte data type. The default marshaling for bool is four bytes (to allow seamless integration with BOOL return values). If you were to use the default marshaling for BOOLEAN values, it's likely that you will get erroneous results. The return directive forces PInvoke to marshal just one byte of the return value.

Try System.Threading.Thread.Start. It doesn't give you all the control of directly calling CreateThread, (such as specifing the flags), but it will get you a vanilla thread to spin up.
