I'm in the process of evaluating Entity Developer for Visual Studio 2010 for the company I work for. After upgrading to the latest version I now get a "Sorry, your trial period has expired" message when trying to create a new model. This morning I still have 17 days in my trial. Is this due to the fact that it's a beta?

Could you please specify the provider you are using (dotConnect for Oracle, MySQL, PostgreSQL or SQLite)?
Are you running a 64-bit system?
Is there any difference between the error message in standalone Entity Developer launch and the error message in VS-integrated launch?

I'm using dotConnect for Oracle on a 64-bit Windows 7.

If I run it from VS-integrated I get a "Sorry, your trial period expired..." message, it creates an empty model but doesn't opens but if I run the standalone it just tells me I have "0 of 30 days left" but it actually opens the model editor.


Edit: Using the Microsoft Entity Framework designer seems to work, including updates. But I have an issue with primary keys: IDs, despite being set to "StoreGeneratedPattern=Identity" are been inserted with the value zero despite a before trigger being active and working from a SQL console. I suspect that zero is being passed to the query so the trigger is not triggered as there is a non-null value in the PK.

We are working on the problem, thank you for the clarification.

We have fixed the problem. The fixed Beta build will be available in a week or so.

Great, thanks for the support.

New build of dotConnect for Oracle 5.55.97 Beta is available for download now.
Please let me know if something goes wrong.

Thanks for the quick reaction time. Identity keys generated by triggers are now correctly being used.

I still have the issue that it says my trial is finished (which it shouldn't) so I can't try the Devart Entity Designer. At least the Microsoft one seems to work well enough plus I couldn't live with not being able to update my model from my DB schema unless I was able to change my DB schema from my model.

Edit:
I didn't notice this on my first test but in the Visual Studio Error List I have the following error:

Error 1 Custom tool error: The specified store provider cannot be found in the configuration, or is not valid. 1 1

This does not seem to prevent my application from working and has only appeared since I've updated from the previous beta.

Is the problem with "Trial period finished" reproducible in standalone mode of Entity Developer?
As for the 'specified provider is not found in configuration, or is not valid' error - please check that you have a connection string in the model and that it is valid.

If I run it from VS-integrated I get a "Sorry, your trial period expired..." message, it creates an empty model but doesn't opens but if I run the standalone it just tells me I have "0 of 30 days left" but it actually opens the model editor.

As for my "specified provider not found" error, it went away after closing VS2010.

Thank you for the clarification, our investigation is still in progress.

Any chance I could get my trial period prolonged?
It has now truly expired (i.e. the component throws a "Sorry, your trial period has expired." error when I run my test application) and with the earlier issues I'm still evaluating the product for my company.

I will let you know as soon as the build with extended trial period is available.
Sorry for the inconvenience.
