LtiLibrary is now a NuGet Package

To make it even easier to add IMS LTI support to your learning app, I wrapped LtiLibrary into its own NuGet Package. To add LtiLibrary to your application, run the following command in the Package Manager Console:

PM> Install-Package LtiLibrary

There is also an LtiLibrary.Sample package which adds sample MVC and Web Forms to an empty ASP.NET Web Application.

PM> Install-Package LtiLibrary.Sample

Using the LtiLibrary.Sample Package

Want to poke around a simple sample application? Try this:

  1. In Visual Studio start a New Project.
  2. Select the ASP.NET Web Application template:
    New Project dialog in Visual Student 2013
  3. Select the Empty template and add folders and core references for Web Forms, MVC, and Web API:
    New ASP.NET Web Application dialog in Visual Student 2013
  4. After the project is created, enter the following command in the Package Manager Console to install LtiLibrary.Sample:
    Package Manager Console in Visual Studio 2013
  5. Run the project and click on the Launch link to launch a sample tool.
    LtiLibrary.Sample MVC home page

LtiLibrary.Sample has MVC, Web Forms, and Web API sample code that implements LTI 1.0, 1.1, and draft 1.2 services. Here is a table of contents for the sample files:

  • LTI 1.0 Tool Consumer and Tool Provider
    • MVC
      • Tool Consumer
        • Controllers\ConsumerController.cs
        • Views\Consumer\Launch.cshtml
      • Tool Provider
        • Controllers\ProviderController.cs
        • Views\Provider\Tool.cshtml
    • Web Forms
      • Tool Consumer
        • WebForms\Launch.ashx
      • Tool Provider
        • WebForms\Tool.aspx
  • LTI 1.1 Outcomes Service
    • Web API and MVC
      • Tool Consumer
        • Controllers\OutcomesApiController.cs
      • Tool Provider
        • Views\Provider\Outcomes.cshtml
  • LTI 1.2 Tool Consumer Profile
    • Web API
      • Tool Consumer
        • Controllers\ToolConsumerProfileApiController.cs

If you are looking for a more robust example of a Tool Consumer and Tool Provider, check out the LtiSamples code in CodePlex.

    Hi,

    i did a test to connect the consumer to another provider (Big Blue Button),
    the Asp .net MVC works very well, but not the Web Forms sample.

    > for Asp .net MVC project i modified:
    on ConsumerController/Launch() methode:

    ConsumerKey = “***”,
    ResourceLinkId = “launch”,
    Url = new Uri(“******”)

    and modify the secret key here
    return View(ltiRequest.GetLtiRequestViewModel(“*******”)); and it works!
    > i did the same thing in the Web Form project: on Launch.ashx.cs

    and modify the secret key here: context.Response.WriteLtiRequest(ltiRequest, “****”);

    but it doesn’t work 😦 , do you see something wrong…? or any suggestion please?
