Kunet.AsyncInterceptor

Build on Push Nuget Version

Inspired by stakx.DynamicProxy.AsyncInterceptor, but rewrite with less reflection to get better performance.

This library allows you to smoothly connect Castle.DynamicProxy with your async/await code, it provides an abstract AsyncInterceptor class, your interceptor inherited from this class can get the ability to intercept method which return value is Task, Task<T>, ValueTask or ValueTask<T>.

class Example : AsyncInterceptor
{
    // This gets called when a non-awaitable method is intercepted:
    protected override void Intercept(IInvocation invocation)
    {
        invocation.Proceed();
        invocation.ReturnValue = ... ;
    }

    // Or this gets called when an awaitable method is intercepted:
    protected override async ValueTask InterceptAsync(IAsyncInvocation invocation)
    {
        await invocation.ProceedAsync();
        invocation.AsyncResult = ... ;
    }
}
