The .NET IRIS dll files and nupkg files are located in the installation directory, in the dev folder. For containers, that would be /usr/irissys/dev/dotnet/bin.

While you are running the IAM setup script, provide the script with a public static IP addres for the host that IRIS (or IRIS container) runs on, and provide the IRIS web server port.

Then after you install IAM, while you are creating a service and sending requests, the IP address should be the address of the host that IAM is running on, and you use an IAM port for incomiong traffic, (e.g. 8000).

Here is documentation about IAM ports for version 3.4.

 And this video about installing IAM has more information: 

According to IRIS docs, "to include custom header parameters [in a JOSE array], ... first define them as key/value pairs in a dynamic object... [then] add it to a node of the JOSE array using the custom subscript."

I forwarded your request to onlinetraining@intersystems.com, which deals with the learning site and learning labs. And I cc'd the email address in your profile.

Here's the correct link for the server-side applications learning path: https://learning.intersystems.com/course/view.php?name=IRIS%20Server%20Side  

And I also recommend this course on RESTful services: https://learning.intersystems.com/course/view.php?name=REST%20Services

Sergei's picture shows a menu located in the InterSystems View. The ISC logo for that view appears on the left of VS Code once you have a ObjectScript connection. You can configure Export settings, to an extent, as {objectscript.export: {}} in workspace or user settings.

See the README on the repository: https://github.com/intersystems-community/vscode-objectscript

You are getting an"invalid JSON" error because the JSON you're POSTing is itself the OpenAPI 2.0 JSON Schema File. It defines how the standard works in JSON.

Instead, you'll need to post an OpenAPI document, abiding by those standards, defining your RESTful service.
