![]() In case you have further questions, do not hesitate to get back to us. However, we are constantly gathering information and preparing resources based on the needs of our users, and I will make sure to update this thread once we are able to provide you with additional details. Assume you have a table called mytemplate in the SQLite3 database file source.db. Regarding the workflow that would unlock the database file in your case, it seems like the scenario you are implementing has a lot of specifics, and currently, we do not offer a reliable out-of-the-box resource that demonstrates it. Optional flags used to determine how to open the SQLite database. That way, the instance of the context will take care to dispose the Database object on its disposal, at the end of the using statement. To avoid the error, you could override the Dispose() method of the context but to remove the explicit call. For example: when the Dispose() method of the context is overridden, an instance of the context is enclosed in a using statement, and then the Dispose() method is called explicitly. Usually, the error you are experiencing occurs when the application tries to dispose the Database object twice. Thank you for your feedback and for the additional information. The workflow for the second approach requires you to extend the context type in a partial class and to override the Dispose() method as demonstrated below: The consideration is that a new instance of the metadata will be created with each instance of the context. The first option would be the recommended one, but if it is not feasible in your scenario note that, the second approach would bring a performance penalty in the application. We can initiate a new SQLite database connection object and assign this object to a variable. The second approach is to override the Dispose() method of the context, and to dispose the metadata in it. This is a lightweight SQL database engine that can be used to create databases stored as files on one’s personal computer. The first one is to split the update of the database and its upload in two applications and to run the second application after the first one has stopped working. You can workaround the issue in two ways. The metadata instance remains cached in-memory during the lifetime of the application, and this seems to be the reason for the behaviour you experience on your side.
