Solar X-rays provide the most direct diagnostics of energetic electron populations during solar flares. I will present recent results concerning particle acceleration and propagation in the solar corona from X-ray observations with the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) and extend the discussion to the need for new X-ray instrumentation using X-ray focusing optics. This instrumental concept was demonstrated with the FOXSI sounding rocket program and I will present results on X-ray diagnostics of microflares obtained with FOXSI observations.
