Hello,

This is a known issue due to Microsoft Visual Studio environment.

This issue does not happen all the time, but when you encounter this issue, there might be a way to fix it.

I found this issue before and what I did was to re-create a new project and re-add the Database (.mdf) in App_Data and re-create the dataset in App_Code.

Or, try to delete the current one you have created. Close the project and re-open it. Re-add the database along with the dataset, and see whether the dataset is displayed in the schema name.

This is the best thing we can do so far for a workaround since the issue came from Visual Studio and we couldn't fix any issue from that environment.

Hope this helps.

Thank you.
