Microsoft Corp has turned to Texas Instruments Inc for help with its repository strategy for component-based application development. The two companies would work together to design a repository to develop complex applications for Windows and Windows NT; no licensing fees are being paid or no equity investments are involved. Texas Instruments also said it would deliver its Information Engineering Facility for client-server for Windows NT in the third quarter. Independent software vendors are to be invited to Redmond this autumn to make suggestions for designing the new repository. Both companies will have rights to sell it. There were no availability dates and no indication of price.
