WebAPI | OHDSI WebAPI contains all OHDSI services

I am working through the Microsoft Learn tutorials to "Create a web API with ASP.Net Core".

Under the heading, "Build and test the web API", at instruction (5) I am getting a response, "Unable to find an OpenAPI description".

For step (6) when executing the "ls" command I get the response, "No directory structure has been set, so there is nothing to list. Use the 'connect' command to set a directory structure based on an OpenAPI description". I have tried the "connect" command suggested here and have tried "dir" as an alternative to "ls".

I can successfully change directories in step (7) and execute the GET request for step (8) and receive the expected reply. However, it really bothers me the "ls" command is not working here and seems like an important function of the httprepl tool.

How can I get the "ls" command to work here or tell me why does it not work?

My new Macbook Pro running on an M1 Max (ARM) chip just came in. I installed Parallels and Windows 11 Preview for ARM, and Visual Studio installs / launches / builds my solution beautifully. Unfortunately the turn windows features on or off dialog doesn't have the option for installing IIS, and others have posted that this is not supported in Windows 11 for ARM.

Our dev team runs multiple ASP.NET Core 3.1 websites locally under IIS using subdomains, e.g.: https://auth-dev.mydomain.com, https://web-dev.mydomain.com, https://webapi-dev.mydomain.com. This was easy to set up in IIS using the bindings dialog, I could specify for port 443 (https) to use a certain subdomain and our dev SSL certificate.

Now I need to figure out how to make this work on Windows 11 ARM. Developing on an inferior non-Macbook Pro laptop doesn't seem like a great solution for .NET devs, I have to assume others with M1 chip Macbook Pros have run into this same issue. What are my options?

I first started looking into using IIS Express, but it seems like every website has to run on a different port, whereas I need them all to run on port 80 (just with different subdomains.) I'd be fine with them running on different ports if there was a way to forward those various ports to the subdomains, but it doesn't seem like the windows HOSTS file supports that.

I also looked into using the Apache web server for Windows, but I read somewhere that it doesn't support running ASP.NET Core apps.

I'm using VS2022 to create a webapi(.net6) project and trying to declaare somme gloabal variables which will be used among webapi controllers. What I did this way:

Declared static variable of type Dictionary at the top level folder of the project:

I have added a webapi project to my solution with a controller to do an HttpGet. The Blazor server project can access it fine locally and deployed. I can make a postman call to the service locally, but the deployed version is giving me the Blazor connection failed message from my _Host file. How would I configure webapi access externally without Blazor interfering?

I think it may be a routing issue of some kind that I need to work out. I am using .NET5 and my webapi startup has this:

I have a webapi that returns some Json:

For now I have a procedure I wish to call:

I need to call a webapi POST method using javascript.

The method accepts a model. I am able to invoke this method correctly from POSTMAN and also see the entries in the database.

Is there a way in C# rx to handle backpressure? I'm trying to call a web api from the results of a paged query. This web api is very fragile and I need to not have more than say 3 concurrent calls, so, the program should be something like:

1. Feth a page from db
2. Call the web api with a maximum of three concurrent calls per each record on the page
3. Save the results back to db
4. Fetch another page and repeat until there are no more results.

I'm not really getting the sequence that I'm after, basically the db gets all the records regardless of whether they can be processed or not.

I've tried a variety of things including tweaking at the ObserveOn operator, implementing a semaphore, and a few other things. Could I get a little bit of guidance to implement something like this?

I am trying to create a unit test using Moq which test Microsoft.AspNetCore.Identity user manager. I know that Moq is good for mocking interfaces, but UserManager does not have interface.

Here is my code:
