I’ve been using a LINQ for SQL model for a project for a few months now. The project has been compiling fine forever now. Suddenly it was failing to build the .dbml file for no apparent reason. A quick search for the problem turned up an issue with Regionate and LINQ for SQL. Uninstalled Regionate and its back to compiling.
I like the tool but until they fix the issue, i’ll have to live without it for a while.
