Some time ago I wrote how to generate C# client for web api with OpenAPI support using online service https://generator3.swagger.io/api/generate. Limitation of this approach is that web api should be available online as well. But what to do if you develop web api and it is available only on localhost? One of the way is to use https://github.com/swagger-api/swagger-codegen but it is not very easy to use it on localhost.
Simpler solution is to use tool called NSwagStudio. At first we need to add support of OpenAPI to our web api - in my previous post I wrote how to do that: Add OpenAPI (Swagger) support to ASP.Net Core Web API. We will use the same code example here.
When we add OpenAPI support to our web api in addition to online documentation (which is available by url http://localhost:{port}/swagger/index.html) we also get endpoint with OpenAPI (swagger) JSON:
http://localhost:{port}/swagger/v1/swagger.json
which looks like this:
Having this endpoint it is very easy to generate strongly-typed C# client for our web api running on localhost using mentioned NSwagStudio. All we have to do is to choose runtime (we will use .NET6), paste url of swagger.json endpoint to the studio, check CSharp Client checkbox and click Generate Outputs:
Here is example of C# client generated for web api from our example with default settings:

Having this client makes it much easier to use our web api from client apps (comparing with developing api calls manually). In addition to that NSwagStudio allows to set many different settings which change generated C# code (e.g. include synchronous method in addition to asynchronous which are generated by default, generate interfaces for client classes for simplifying unit testing, default namespace, etc):
You may check other settings when will play with NSwagStudio which for sure worth to spend some time on it. Hope that this knowledge will help to reduce development time and simplify consumption of your web APIs.
