Create a REST TestServer with, Get, Post, Delete, Push

• GET   Read or retrieve data
• POST  Add new data
• PUT   Update data that already exists
• DELETE Remove data

I need to test this via a C# WPF desktop application. For this I need a SERVER. How can I achieve this quickly and easily? 
There is so much information that is difficult for a beginner to understand.

static async Task Main(string[] args)
{
	// Your XML string
	string xmlData = @"<Request><Data>Hello, REST Interface!</Data></Request>";

	// The URL to send the POST request to (update with your local server URL)
	string url = "https://localhost:5044/api/MyHomeController";

	// Create a new HttpClient instance
	using (HttpClient client = new HttpClient())
	{
		// Set the content type to XML
		HttpContent content = new StringContent(xmlData, Encoding.UTF8, "application/xml");

		// Send the POST request
		HttpResponseMessage response = await client.PostAsync(url, content);

		// Ensure the response was successful, or throw an exception
		response.EnsureSuccessStatusCode();

		// Read the response content
		string responseContent = await response.Content.ReadAsStringAsync();
	}
}
