Remarks

To create a Middle Tier client, configure its settings with the MiddleTierClientBuilder<TDbContext> and call the Build() method. Once created, the client is immutable.

csharp

// Configures client `DbContext` type, server, and authentication settings
var builder = new MiddleTierClientBuilder<MainDemoDbContext>()
    .UseServer("http://localhost:5000/")
    .UsePasswordAuthentication("user", "password");

// Creates a Middle Tier client instance
IMiddleTierClient<MainDemoDbContext> client = builder.Build();

// Creates DbContext and operates data
using(var ctx = client.CreateDbContext()) {
    var data = ctx.Users.ToList();
    // ...
}

// Disposes the client
// Note that it is necessary to manually dispose the client when its instance is no longer needed
client.Dispose();
