I have a Delphi code-first server that serves some C#.NET clients (Xamarin). I’d like to generate an Intf file whenever I make changes to the server. Ideally this could be performed in the post build event. Currently I use a batch file that calls rodl2code with URL to generate c# Intf file, however there are two issues: - the server must be running - I have to use RO…HTTPServer, but I use supertcp to communicate with server in production Maybe I’m missing something. I was used to autogenerated Intf files since all my servers was RODL-based and clients were Delphi only. I also saw this feature in [What’s New in Remoting SDK and Data Abstract 10](https://www.remotingsdk.com/ro/whatsnew/) under ‘New in .1491, October 27, 2020 (Stable)’: - Improve generation of RODL from CodeFirst services However I have no idea what that means and anyway I’m on version 9.7.115.1441. ---

Hi, > [@juraj.polacok](#): > > the server must be running this is feature of the Code-First projects - RODL is generated on fly in runtime from RTTI information. > [@juraj.polacok](#): > > I have to use RO…HTTPServer, but I use supertcp to communicate with server in production you should be able to use `supertcp://` protocol too. > [@juraj.polacok](#): > > Currently I use a batch file that calls rodl2code with URL to generate c# Intf file you can improve this process: - check [Tool rocg4\_helper](https://talk.remobjects.com/t/tool-rocg4-helper/22749) topic, it contains simple `rocg4_helper` utility that shows how to generate files using `uROCodegen4Helper.pas`. - you can add some command line option for your server so it will be started, generates \_Intf files via `uROCodegen4Helper.pas` and exits. **Note** : _developer pc with RO SDK installed is required for this solution._ > [@juraj.polacok](#): > > I also saw this feature in [What’s New in Remoting SDK and Data Abstract 10](https://www.remotingsdk.com/ro/whatsnew/) under ‘New in .1491, October 27, 2020 (Stable)’: > > - Improve generation of RODL from CodeFirst services check this topic at beta forum - it describes what exactly was improved: [https://talk.remobjects.com/t/remoting-sdk-for-delphi-vnext-new-features/18354/32](https://talk.remobjects.com/t/remoting-sdk-for-delphi-vnext-new-features/18354/32) ---

> [@EvgenyK](#): > > you should be able to use `supertcp://` protocol too. I tried that before asking, but it seems that rodl2code then treats the parameter as file name (at least in version 9.7.115.1441): > \> rodl2code.exe supertcp://host:port --type:intf --platform:.net --language:c# > Processing RODL file supertcp://host:port > File supertcp://host:port Besides that, `rodl2code` prints this information when no parameters given (emphasis mine): > Remoting SDK Service Interface Code Generator, based on CodeGen4 ([GitHub - remobjects/CodeGen4: A Swift library to generate source code for many languages](https://github.com/remobjects/codegen4)) > > Syntax: > > rodl2code \ --type:\ --platform:\ --language:\ --namespace:\ > rodl2code \ --service:\ --platform:\ --language:\ --namespace:\ > rodl2code \ --services --platform:\ --language:\ --namespace:\ > > \ can be: > > - the path to a local .RODL file > - the path to a local .remoteRODL file > - **a http:// or https:// URL for a remote server** > … `uROCodegen4Helper` seems as a viable option for me that I’m going to explore further. Many thanks for your help. ---

Hi, C# is supported over supertcp: ![untitled](https://talk.remobjects.com/uploads/default/original/2X/f/f2cbf7577ca1b6820d7385cfb8b95be78a21a785.png) ---

I have followed your advice to add a command line switch to my service that allows me to generate Intf files using `TROCodegen4` class. All was going well until I discovered that it internally uses 32-bit Codegen4Wrapper in-proc COM server. The problem is that my service is 64-bit, so the code generation fails (Class not registered) and I don’t want to maintain Win32 target just for this purpose. I’m not a COM wizard, so the question is whether it is possible to load 32-bit COM server into 64-bit app (maybe as an out-of-proc server)? Otherwise I will just execute `rodl2code.exe` from within my service when the command line option for generating Intf is present. ---

Hi, you can register it with > C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe RemObjects.SDK.CodeGen4.dll We will update install and this assembly will be registered in x64 space too. ---

Maybe installer already registers the assembly for x64, but I do the manual installation process as discussed here: > [@Manual installation of RemObjects SDK](https://talk.remobjects.com/t/manual-installation-of-remobjects-sdk/23125): > > I’m trying to get RemObjects SDK into source control since I need to support multiple versions of my application that was compiled with different version of library (9.7.115.1441 and 10.0.0.1485). This would allow me to: rapidly switch between two version of my application make initial setup of development environment easier For that purpose I performed these steps: I backed up original installation files. I uninstalled RemObjects SDK. I added BPLs, DCUs, DCPs and optionally source code fil… I will update my scripts with x64 registration.
