I have an application from a company that went out of business. It appears to use the SQL Server CE database. I have searched the system and can't find any .sdf files. It appears that the database has grown too big. Any idea how I can find the DB and change the maximum size?
ERROR message:
Unable to log application start. - System.Data.EntityCommandExecutionException: An error occurred while reading from the store provider's data reader. See the inner exception for details. --->
System.Data.SqlServerCe.SqlCeException: The database file is larger than the configured maximum database size. This setting takes effect on the first concurrent database connection only. [ Required Max Database Size (in MB; 0 if unknown) = 257 ]
You need to locate the connection string and add: Max Database Size=1024
(Max is 4000)
