1. An assembly for a gas turbine engine comprising: a frame;a strut extending from the frame;a mount attached to the frame, the mount comprising:a ring extending around an engine centerline and having one or more slots therein, wherein each slot has side walls extending in a radial direction relative to the frame and an end wall joining the side walls; anda fairing connected to the mount, the fairing comprising:an outer radial surface;an inner radial surface;a vane extending from the outer radial surface to the inner radial surface, wherein the vane is disposed around the strut; andone or more lugs extending from one of the outer and inner radial surfaces that have mating walls, each mating wall extending in a substantially axial direction relative to the frame and disposed opposite one of the side walls of one of the slots,wherein the one or more lugs are received in the one or more slots; wherein the one or more lugs of the fairing and the one or more slots of the mount are mating anti-deflection features that engage to allow unconstrained movement of the fairing in both the radial direction and the axial direction relative to the frame but is constrained from movement in a circumferential direction with respect to the frame. 2. The assembly of claim 1, wherein the mount is attached to a first axial end portion of the frame. 3. The assembly of claim 2, wherein the mount is attached to the frame by a first fastener and wherein the fairing is attached to a second axial end portion of the frame by a second fastener. 4. The assembly of claim 3, wherein the mount is attached to an outer radial platform of the frame and the fairing is additionally attached to an inner radial platform of the frame. 5. The assembly of claim 1, wherein the frame comprises a turbine frame. 6. An assembly for a gas turbine engine, comprising: a frame;a strut extending from the frame;a mount attached to the frame, the mount comprising:a ring extending around an engine centerline and having one or more slots therein, wherein each slot has side walls extending in a radial direction relative to the frame and an end wall joining the side walls; and a fairing that defines a gas flow path for the gas turbine engine, wherein the fairing is disposed around the strut and has a first fixed connection to the frame and a second connection to the frame, and wherein the second connection allows for both radial and axial movement of the fairing relative to the frame while preventing circumferential movement of the fairing relative to the frame, and wherein the second connection comprises:one or more lugs extending from the fairing, wherein each lug has mating walls extending in a substantially axial direction relative to the frame, each mating wall disposed opposite one of the side walls of one of the slots, and wherein the one or more lugs are received in the one or more slots. 7. The assembly of claim 6, wherein the ring is mounted to a first axial end portion of the frame. 8. The assembly of claim 6, wherein the ring is mounted to the frame by a first fastener and the fairing is mounted to a second axial end portion of the frame by a second fastener. 9. The assembly of claim 7, wherein the ring is mounted to an outer radial platform of the frame and the fairing is mounted to an inner radial platform of the frame. 10. The assembly of claim 6, wherein the frame comprises a turbine frame. 11. A turbine section for a gas turbine engine, comprising: a turbine frame disposed along an axial length of the turbine section;a strut extending from the turbine frame;a fairing disposed within the turbine frame to form a gas path for the turbine section, the fairing comprising:an outer radial surface;an inner radial surface; anda vane extending from the outer radial surface to the inner radial surface, wherein the vane is disposed around the strut; anda mount attached between the fairing and the turbine frame, wherein the mount comprises a ring extending around an engine centerline, wherein the mount and the fairing have mating features that constrain the fairing from movement in a circumferential direction with respect to the turbine frame but the mating features allow for unconstrained movement of the fairing in both a radial and an axial direction relative to the turbine frame, and wherein the mating features comprise:one or more slots within the ring, wherein each slot has side walls extending in a radial direction of the turbine frame and an end wall joining the side walls; andone or more lugs extending from the fairing, wherein each lug has mating walls extending in a substantially axial direction relative to the turbine frame, each mating wall disposed opposite one of the side walls of one of the slots, and wherein the one or more lugs are received in the one or more slots. 12. The turbine section of claim 11, wherein the fairing is attached at a first axial end portion to the frame by a fastener and is constrained from movement in the circumferential direction with respect to the frame at a second axial end portion of the fairing. 13. The turbine section of claim 11, wherein the mount is attached to an outer radial platform of the frame.
