    "System.Data.SqlServerCe.SqlCeLockTimeoutException: SQL Server Compact timed out waiting for a lock." when editing Member

    I have some code which deals with creating and updating Members. For reasons out-of-scope of this issue, the code which creates a member (using an Umbraco Forms Custom Workflow) passes the MemberId and other info to another function which is in a WebApi, by POST. The WebApi uses the MembershipService to get an instance of the member just created and set some additional property data, then saves the member.

    When I run this locally using SQLCE DB, the WebApi code always fails with "System.Data.SqlServerCe.SqlCeLockTimeoutException (0x80004005): SQL Server Compact timed out waiting for a lock."

    It seems that the initial code is somehow locking that single new Member record, but I'm not sure how to "unlock" it after I save the member, and before I call the WebApi...

    This is the full error:

    System.Data.SqlServerCe.SqlCeLockTimeoutException (0x80004005): SQL Server Compact timed out waiting for a lock. The default lock time is 2000ms for devices and 5000ms for desktops. The default lock timeout can be increased in the connection string using the ssce: default lock timeout property.

    Does anyone have ideas about how to handle this?
