Following up on this, the NSwag docs are definitely not as user friendly as the EasySdk site, but I was able to install and run the windows GUI app for NSwag and compare handling of a moderately large swagger file. EasySDK generated a TypeScript file that was 1/4 the size, far more readable, and from what I could tell as capable as the NSwag generated TypeScript file. That said, NSwag can generate C# files which EasySdk can not do (yet). Kiota (mentioned elsewhere in the comments) was unable to parse the swagger file.
