as google does not deliver what i want to know, i try to ask stackoverflow :) what is the number of max concurrent connections to a sql ce 3.5 database? thanks j.
I believe the information you are looking for is the SQL Server Edition Comparison.
For standard Editions - Compare Features
For Compact Edition - Compare Features
Edit
Sorry, this Word Document is most likely what you need.
Edit again
The answer is 256 concurrent connections for Compact, unlimited for express. See table 1 in the linked word doc.
