ltilibrary / ltiadvantageplatform

Sample LTI Advantage Platform.

LTI Library

There are two .NET Standard 1.6/2.0 projects in this solution to support IMS LTI Tool Providers and Tool Consumers. The Visual Studio solution and project files are compatible with Visual Studio 2019.

See the LtiLibrary1.6 repository for the last non-.NET Standard source for LtiLibrary.


LtiLibrary.NetCore

This is the only library you need if you are going to roll your own support for web pages or native apps.

This library includes the classes, properties, and methods to support LTI 1.1.1 launch, outcomes, content items and tool consumer profiles for both Tool Consumers and Tool Providers.

Available on NuGet:

Ltibrary.AspNetCore

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.

Available on NuGet:

Test Projects

There are also two xUnit test projects: one for each project above. These can be helpful examples for how to use the libraries.

Missing projects and their references

This repo has two missing project references i.e

 <ProjectReference Include="..\..\..\LTI\LtiAdvantage\src\LtiAdvantage.IdentityServer4\LtiAdvantage.IdentityServer4.csproj" />
 <ProjectReference Include="..\..\..\LTI\LtiAdvantage\src\LtiAdvantage\LtiAdvantage.csproj" />

Please add missing projects and references so that we can move further for a sample idea of LTI Advantage Library.

Upgrading to LTI Advantage/ LTI 1.3

Hello,

I am new to this tool and am going through documentation to understand how I can migrate our existing code to v1.3. Any pointers to help me get started on this migration would greatly help. Thanks!

LineItemsControllerBase missing error

Hello, when i open the project in Visual Studio 2022, i am getting multiple errors

I saw that the missing classes exist in the folder of the solution for the LTI Advantage library in
LtiAdvantage\src\LtiAdvantage.AspNetCore\AssignmentGradeServices
Do I have to add a reference to that somehow?
