Made With Reflect4 Proxy List Here

| Aspect | Impact | |--------|--------| | Proxy creation | Moderate overhead (reflection + IL generation). Cache proxies if reused. | | Method interception | Small overhead per call (virtual method dispatch, interceptor chain). | | Memory | Each proxy adds a small wrapper object. Fine for hundreds, monitor for thousands. |

Tip: For high-throughput scenarios, prefer interface proxies (CreateInterfaceProxyWithTarget) over class proxies.

var proxy = proxyGenerator.CreateInterfaceProxyWithTarget<IService>(
    new RealService(),
    interceptor
);

public interface IApiClient
Task<string> GetDataAsync(int id);
public class RetryInterceptor : IInterceptor
public void Intercept(IInvocation invocation)
int retries = 3;
while (retries-- > 0)
try
invocation.Proceed();
return;
catch
if (retries == 0) throw;
Thread.Sleep(100);
 made with reflect4 proxy list
// Create a list of proxied API clients
var clients = new List<IApiClient>();
for (int i = 1; i <= 10; i++)
var realClient = new SomeApiClient($"https://api.example.com/endpointi");
var proxy = proxyGenerator.CreateInterfaceProxyWithTarget<IApiClient>(
realClient, new RetryInterceptor()
);
clients.Add(proxy);

First, install the required NuGet packages:

dotnet add package Castle.Core
dotnet add package reflect4 (if using reflect4 helpers)
