It would be excellent to make the WorldCreator through the Middle-Tier Applicaton Server

[YARSUN]

As far as I understood, I was not alone asking such a question (http://www.expandframework.com/forum/8-discussion/1920-worldcreator-and-xaf-application-server.html , http://www.expandframework.com/forum/8-discussion/5065-application-server-with-worldcreator.html) and it would be great to realize the availability of objects who created with the help of WorldCreator through the Middle-Tier XpandServerApplication.
If I can help in this matter - please let me know. I did a lot of tests and experiments. Maybe for start - it's possible to load WC (example: through creating Win application in app server code started and after - upload/inject dynamically types to the XpandServerApplication exported types) module when ServerApplication is started...

Thanks for the offer however I cannot suggest at the moment what needs to be done as I need time for research. What is your timeframe for this?

[YARSUN]

You really flash) We have the time until about 10.2018-11.2018. If in this frame time this task in any - even the most complex and uncomfortable performance will be solved, it will be cool. Next we will be equal in proportion to your development. Otherwise, we will have to "dance with a tambourine" and try to make our generator/modifier of objects and somehow "screw" it to the XAF (((

[apobekiaris]

the time is more than enough I will update you again when I spent some time researching deeply.

[YARSUN]

Thank's for you Work Apostolis! Great! Will be waiting for updates...

Hello, any news ? :)

[YARSUN]

Hi! Nop) at the current time.

[apobekiaris]

it is possible with this patch (see Demos/Middle Tier/E4036-WCF solution in the included sources) to run Worldcreator both on the server and on client. For this you need to use the same clasess used in the Program.cs files and provide a WorldCreatorConnestring in both app.config. Note of course that server has no UI and if a client uses worldcreator means that the model only for that client would changed and will lead to problems unless the server and all clients are restarted. I think a simple notification using the nottification module would benefit here but not sure maybe you can feedback if needed.

[YARSUN]

Thank's Apostolis! I'll try path and make a review.

Hi Apostolis! It's not working, I'll try update my project and sample in Demos/Middle Tier/E4036-WCF:

I'am not understand why.

[apobekiaris]

where does this happen? in the modified demo? can you post it? does the demo work as expected b4 modifying?

[YARSUN]

Hi!
For sample project: No, I just update sample project to last XAF library and Xpand.
For my project - how can I send to you in private channel?
