Please send us a test project with the necessary DDL scripts, so that we are able to investigate your scenario in more details. This will significantly speed up the process of finding the solution for you.
Please also tell us the exact product you are using (LinqConnect or dotConnect for Oracle) and its version.

Looking forward to your reply.

We couldn't reproduce this behaviour with simple queries, such as "select * from...", etc.
If possible, please send us a complete test project with the necessary DDL scripts, with which this issue is reproducible. This will significantly speed up the process of determining the cause of the issue and finding the solution for it.
Please also tell the exact product you are using (LinqConnect or dotConnect for Oracle) and its version.

Looking forward to your reply.

Are we able to install both versions of Devart on the deployment server?

Please tell us if this information helps.

The investigation is in progress. We will definitely inform you about the results as soon as any are available.

We have provided you with a small test project, helpful links and general information regarding working with the standard Microsoft technology - LINQ to SQL.
Unfortunately, your further questions are beyond the scope of our support, we provide support on technical Entity Developer/LinqConnect specific questions.
If you have any questions regarding working with Entity Developer/LinqConnect or encounter any other specific issues, errors with these products, etc., feel free to contact us.

We are sending you a small test project to the e-mail address you provided in your forum profile. Please check that is not blocked by your mail filter. Please test it and notify us about the results.
If this doesn't help, please describe the issues you are encountering in more details, modify our sample so that the issues can be reproduced and send it back to us, or send us your sample project.

Some useful information:

Unfortunately, such scenarios are not supported in LINQ Insight.

Thank you for the report on this. We have reproduced this issue. We will investigate it more clearly and inform you about the results as soon as possible.

The bug with determination of NULL values as strings while reading metadata for columns with "DEFAULT NULL" via the Database-First approach is fixed (SQLite).

New build of LinqConnect 4.5.930 is available!
It can be downloaded from http://www.devart.com/linqconnect/download.html (trial version) or from Registered Users' Area (for users with active subscription only).
For more information, please refer to http://forums.devart.com/viewtopic.php?f=31&t=33202.

does that mean you do not need to purchase a LinqConnect license separately?

Yes, dotConnect for MySQL Professional/Developer Edition includes Entity Developer, which supports LinqConnect and Entity Framework models using the corresponding provider only. E.g. with dotConnect for MySQL Professional/Developer, you will be able to use bundled Entity Developer for creating Entity Framework and LinqConnect models for MySQL databases only.
Please refer to http://www.devart.com/dotconnect/mysql/editions.html.

If this information doesn't help, please specify your goal in more details (which ORM(s) and DBMS(s) you are going to use), so that we are able to recommend you which products to use.

No, it is not supported in LinqConnect. We will consider the possibility to add this support, but we can't tell any timeframe at the moment. We will inform you about the results as soon as any are available.

It would be grateful if you send us the test project and the detailed steps for reproducing the issue (including, the description of the expected and incorrect behaviour).
For example, we've created sample projects with and without LinqConnect model, and the behaviour is the same in both cases.

Also, try attaching one Visual Studio instance (Debug | Attach to Process) to the process of another Visual Studio instance with the project, where the error occurs and send us the full text of the exception (if you'll manage to get one).

Thank you for the reply.
We are processing your request by e-mail. We will contact you as soon as possible.

We've sent you "LoquaciousMapping" template to the e-mail address you provided in your forum profile. Please check that is not blocked by your mail filter.

Yes, you can use the partial class and OnCreated() method:

You can also try passing one or another connection string to your data context constructor, depending on where the code is being executed (at the local development machine or at the production server), for example, using the compilation conditions for this: This code will determine what connection string to use according to the solution configuration (Debug or Release). And then create your DataContext object using the necessary connection string.
The choice of possible options for such scenario depends on your specific aspects, preferences, etc.

If you have any further questions, feel free to contact us.
