The provider did not create a CommandDefinition

Post by skoub » Wed 09 Sep 2015 17:58

i have an intermittent problem. I get this error message in my application for no particular reason because when i call a refresh to this page, the problem disappear. The application can run for a few hours without problem and then decide to throw an exception. So i cannot give you a test projet for that particular reason.

I'm running my app with MVC5, Framework 4.5.2 and Devart v8.5.478.0 (also tried with v8.4.359.0).

Code: Select all

System.Data.Entity.Core.ProviderIncompatibleException: The provider did not create a CommandDefinition. ---> System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

1. Turn on the dbMonitor tool. Is there any failed SQL statement in dbMonitor when the application throws the ArgumentOutOfRangeException?
2. Please try to localize the issue and send us a small test project with the corresponding DDL/DML script for reproducing.

Its difficult to trap the error because it's intermittent but i can confirm that the sql statement is not sent to the database (dbMonitor).

Looks like your code creates and adds new object/objects, saves them in DbContext/ObjectContext using SaveChanges(). I.e. you can extract all EF model files (code of model, classes, xml files if any) and connection string from your huge project. Then add these files to a separate newly created test application, implement a multithreading where each thread will add/save exactly the same object/objects which cause the fail.

This should be enough for reproducing. If so, please send us your test application with the corresponding DDL script for reproducing.
