This sample runs a a MUv6 update server.

The update server delivers updates to Windows Update clients that have been configured through group policy to connect to it. For more information, see Specify intranet Microsoft update service location

Fetch some Windows updates before running this sample. A good starting point is to sync classification "Security Updates" for the "Windows 11" product.

// Load the default configuration for the MUv6 server
// The default configuration JSON file is stored with the upsync tool code
var serviceConfigurationJson = File.ReadAllText("./update-server-config.json");
var metadataPath = "./store";
var contentPath = "./content";
// Do not use localhost; bind to an endpoint accessible
// to the devices you want to update.
var bindEndpoint = "localhost;
var bindPort = 40080;

var host = new WebHostBuilder()
    // Bind to an IP address of HOST NAME
    // Use the same endpoint information when configuring update group policy on the devices
    // that should get updates from this server
    .UseUrls($"http://{bindEndpoint}:{bindPort}")
    // Use the sample MUv6 server startup. Use the sample startup code as a starting 
    // point for customization
