I’ve been using IAsyncEnumerable recently for the streaming of SQL query rows and of deserialized objects from API calls and while it seems to work like a charm it does seem to have a few configuration issues. Firstly, on creating a new .NET Core project in Visual Studio 2019 (v16.3.5) Read more…
While there seems to be plenty of resources and guides out there to help users create an API there seems to be much less guidance on how to create a client for accessing an API. I’m fine with calling an API using HttpClient or through a library such as RestSharp Read more…
