Important note about accessibility: In version 1.3 of the schema we introduced a label property on Inputs to improve accessibility. If the Host app you are targeting supports v1.3 you should use label instead of a TextBlock as seen in some samples below. Once most Host apps have updated to the latest version we will update the samples accordingly.
