The WireMock admin API provides functionality to define the mappings via a http interface see Wiki : Admin API Reference.
⭐ Using
WireMock.Net can be used in several ways:
UnitTesting
You can use your favorite test framework and use WireMock within your tests, see Wiki : UnitTesting.
Unit/Integration Testing using Testcontainers.DotNet
See Wiki : WireMock.Net.Testcontainers on how to build a WireMock.Net Docker container which can be used in Unit/Integration testing.
Unit/Integration Testing using an an Aspire Distributed Application
See Wiki : WireMock.Net.Aspire on how to use WireMock.Net as an Aspire Hosted application to do Unit/Integration testing.
As a dotnet tool
It's simple to install WireMock.Net as (global) dotnet tool, see Wiki : dotnet tool.
As standalone process / console application
This is quite straight forward to launch a mock server within a console application, see Wiki : Standalone Process.
As a Windows Service
You can also run WireMock.Net as a Windows Service, follow this WireMock-as-a-Windows-Service.
As a Web Job in Azure or application in IIS
See this link WireMock-as-a-(Azure)-Web-App
