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:

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

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

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.

Let me know if you find this useful.

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?

  I’m sorry, but I’m not able to help debug your code.

Thank you for the sample, the WebForm works only on Internet Explorer and not with chrome and firefox.
