Blender 2.8 beta and latest build
Converting a mesh with modifiers to a mesh without modifiers (applying modifiers) does not work in 2.8
-Open the attached blend:
-The selected cube has shrinkwrap modifiers to project onto the other cube
-Press F3 > type "Convert To" > run the operator "Mesh from Curve/..."
-The cube data are reset instead of being applied
Important note: It seems to depend on the modifier. For example the Subsurf modifier work, the Shrinkwrap does not.
