Warning
This repo is soley maintained to support organisations that are still forced to deal with legacy LTI implementations. All current .Net development should be based on LtiAdvantage the successor of this repo for LTI 1.3/LtiAdvantage [1EdTech]
In 1EdTech/IMS Global's LTI Security Bulletin from July 2019, LTI 1.0/1.1/2.0 were deprecated as they relied on obsolete and no longer secure standards. They ended support three years ago on June 30, 2022:
All support for LTI versions 1.0, 1.1, 1.1.1, 1.1.2, 1.2, and 2.0 will end on June 30, 2022. All institutions and suppliers should adopt LTI 1.3 and LTI Advantage for teaching and learning integration to receive its many benefits.

This library depends on LtiLibrary.NetCore and adds useful extensions and helper methods for ASP.NET Core 2.0+ applications such as an OutcomesApiController which implements the LTI Outcomes API as a Controller.
There are also two xUnit test projects: one for each project above. These can be helpful examples for how to use the libraries.
