visual studio 2012 - Entity Framework Code First Default Database Location -

i trying follow video tutorial on http://msdn.microsoft.com/en-us/data/jj193542 using visual studio 2012 express desktop.

i created poco's, , dbcontext, ran sample queries , worked. did not provide connection string. database? (sdf or mdf file maybe?)

during tutorial guy uses sql server object explorer view database, couldn't find view in vs express.

for reference, here default app.config gets generated.
