(I'm not sure of ASP.Net MVC's compatibility with Mono but it could be a good start) You may also find some interesting keys with json services (with JSON.Net for example) http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment29http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment29Mon, 11 Jan 2010 20:58:21 GMTBecause I initially thought that WCF is completely not an option http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment28http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment28Sun, 10 Jan 2010 06:26:46 GMTI'm sure you thought of this, but if you have a moment can you explain why a separate proxy layer/service/wrapper that translates between Remoting and WCF is not a good option? http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment27http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment27Sun, 10 Jan 2010 03:23:19 GMT@Frans, Thanks you for defining someone a "daredevil", it makes me feel younger. Less polite is the "big mounth",but I know, is the price we have to pay for you sharing your wisdom. but is Actually the 'personal' contrib version i'm talking about is on the offical contrib version. I do not have so much useless time to spent, this is the reason my work is for sure a little monkey in comparison to your. I just did it cause NH give me a lot of productivity and I would like to pay back something. Basically I'm really surprised on seeing so many people complaining for documentation, the site NHForge is plain of whatever you need to starup with NH. Plus you have the source code. Plus you have a lot of people helping you basically for free ( Fabio Maulo one of the best,Ayende as well). Furthermore, the fancy designer with fancy colored boxes is a "must have" that fail as soon the model pass the 15 entities... http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment26http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment26Thu, 07 Jan 2010 20:36:20 GMTThe actual serialization format isn't what worries me. http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment25http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment25Thu, 07 Jan 2010 09:28:26 GMTIt solves you problem without needing to have an external technology which is may not implemented in another platform.

What do you mean but the extra one step that you are talking about. I thought it just be same for both? http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment16http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment16Wed, 06 Jan 2010 15:34:09 GMTMarc, I know, but that step is an extra one that I really don't want to do http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment15http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment15Wed, 06 Jan 2010 13:26:32 GMTIs the Mono server on linux? On Windows you don't actually need to be admin to use HttpListener - you just need the port opened for http.sys (via netsh etc). Is there maybe something similar for linux? http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment14http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment14Wed, 06 Jan 2010 13:20:20 GMTMarc, I need to run it as non admin user http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment13http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment13Wed, 06 Jan 2010 13:16:25 GMT@Ayende - I don't fully understand the question, but note that the current server implementation uses HttpListener, so if that is a problem... But I'm on about the RPC stack in protobuf-net; examples are in the unit-test project - see the HttpWithLambda test-fixture here: [code.google.com/.../HttpBasic.cs](http://code.google.com/p/protobuf-net/source/browse/trunk/Examples/Rpc/HttpBasic.cs)http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment12http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment12Wed, 06 Jan 2010 13:08:20 GMT@Ayende Yeah admin rights is a problem with HttpListener. This is where the other options may be more appropriate. On the upside HttpListener allows you to host on the same port at the same time with IIS. Just sent you an email - I'm happy to change it to a more appropriate licence if needed. http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment11http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment11Wed, 06 Jan 2010 13:08:10 GMTOn second thought, Demis, I checked out the license, and it is GPL, which mean that I pretty much can't make any use of it http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment10http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment10Wed, 06 Jan 2010 12:17:24 GMTMarc, What implementation are you talking about? http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment9http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment9Wed, 06 Jan 2010 12:14:58 GMTDennis, I'll look at that. My issue with HttpListener is that it requires admin privileges http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment8http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment8Wed, 06 Jan 2010 12:14:28 GMTSounds like a good spot for a plug. You can use Service Stack ( [http://www.servicestack.net](http://www.servicestack.net)) - an opensource XML/JSON/REST web services framework that runs on .NET or Mono which can be hosted in IIS, XSP or even inside a standalone console app (which uses HttpListener behind the scenes). This link below shows a live 'silverlight client' talking to XML services hosted on CentOS/Nginx server: [www.servicestack.net/.../Silverlight.htm](http://www.servicestack.net/ServiceStack.Examples.Clients/Silverlight.htm) For a quick overview on servicestack here's an in-depth tutorial creating and calling mono webservices from a MonoTouch client (C# on iPhone): [http://www.servicestack.net/monotouch/remote-info/](http://www.servicestack.net/monotouch/remote-info/) http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment7http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment7Wed, 06 Jan 2010 11:35:26 GMTRe the protocol buffers / RPC discussion; protobuf-net has a basic RPC stack built in using HTTP, covering those error-handling, method-invocation, etc issues. I honestly haven't tried it between Silverlight and Mono, so I can't guarantee that it'll work. If you're on a framework with Expression, it allows usage like: var result = proxy.Invoke(svc => svc.SomeMethod("abc", someArg, obj.SomeValue)); Without Expression it is a bit less pretty. http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment6http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment6Wed, 06 Jan 2010 11:13:40 GMTRich, I am using it there, but I use it as data stream, not RPC. For RPC, you would need to handle a lot of things, such as error handling, method invocation, etc. http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment5http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment5Wed, 06 Jan 2010 10:56:37 GMTwell, the simplest way to do this if you can use the mono version with WCF support is Agatha :) http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment4http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment4Wed, 06 Jan 2010 10:54:12 GMTI thought you used ProtocolBuffers in UberProf - can you use that to send messages between processes instead of RPC? http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment3http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment3Wed, 06 Jan 2010 10:54:08 GMTAnd that is why I love this blog :-) Thanks, I'll check this out http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment2http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment2Wed, 06 Jan 2010 10:31:12 GMTCan you pick the Mono version? 2.6 has the WCF stack from Silverlight, IIRC. http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment1http://ayende.com/4353/nih-alert-writing-my-own-rpc-systems#comment1Wed, 06 Jan 2010 10:11:20 GMT
