I would like to embed depencency dll into my HttpHandler dll for easier deployment, so I was thinking to add it to solution as embedded resource and use AppDomain.CurrentDomain.AssemblyResolve
event to resolve it.
Problem is, that if I subscribe to event in void ProcessRequest(HttpContext context)
method, looks like it fails to resolve before it reaches event subscription.
So question would be where should I subscribe to that event, to be able to load dll from embedded resource.
You could use the static constructor of your handler. For example:
public class Handler1: IHttpHandler
{
static Handler1()
{
AppDomain.CurrentDomain.AssemblyResolve += (sender, e) =>
{
if (string.Equals(e.Name, "ClassLibrary1", StringComparison.OrdinalIgnoreCase))
{
using (var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("Handler.ClassLibrary1.dll"))
{
var buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
return Assembly.Load(buffer);
}
}
return null;
};
}
public void ProcessRequest(HttpContext context)
{
var mtd = Type.GetType("ClassLibrary1.Class1, ClassLibrary1").GetMethod("Hello", BindingFlags.Static | BindingFlags.Public);
var result = (string)mtd.Invoke(null, null);
context.Response.ContentType = "text/plain";
context.Response.Write(result);
}
public bool IsReusable
{
get { return true; }
}
}
