• Using Entity Framework (code first) migrations in production

  - by devdigital

  I'm just looking into using EF migrations for our project, and in particular for performing schema changes in production between releases. I can see that generating SQL (delta) script files is an option, but is there no way of running the migrations programmatically on app start up? Will I instead need to add each delta script to the solution and write my own framework to apply them in order (from the current version to the latest) on bootstrap?

• The entity framework and database agnostic programming, possibilities?

  - by Theo

  We want to use the Entity Framework (.NET 4.0) to build applications that can deal with Sql Server, MySQL and Oracle. And maybe Sqlite too. It should be easy to switch the db vendor by some setting in a config file. Is this possible? I prefer real life examples! What kind of providers did you use?

• lightweight publish/subscribe framework in java

  - by mdma

  Is there a good lightweight framework for java that provides the publish/subscribe pattern? Some ideal features Support for generics Registration of multiple subscribers to a publisher API primarily interfaces and some useful implementations purely in-memory, persistence and transaction guarantees not required. I know about JMS but that is overkill for my need. The publish/subscribed data are the result of scans of a file system, with scan results being fed to another component for processing, which are then processed before being fed to another and so on.

• default value support for Entity Framework object construction to avoid having to set this column pa

  - by Greg

  Hi, In entity framework is there a way to have a default value for a column such that Linq to Entity won't require this parameter when constructing a new object? For example I've marked on column in the EF designer with a default value (I typed in "All" as it was a string). But if I try to construct a new record and not specify this parameter I still get a FOREIGN KEY constraint exception. The INSERT statement conflicted with the FOREIGN KEY constraint "FK_FunctionalityTypeInterfaceRelationship"

• WCF hosting in .NET compact framework

  - by jauwaad

  I would like to host a service on a WinCE device. The WinCE device is the host which can be accessed(control and data acquisition) by multiple clients (PC or WinCE) over serial port, TCP, USB etc. I was considering using Protocol Buffers for serialization on the wire. It would be ideal to use WCF or remoting but as far as I see they are not implement on the Compact Framework. Anyone have any ideas how this can be achieved.

• Concurrency checking in Entity Framework with stored procedures while deleting

  - by bodziec

  Hi, My UPDATE and DELETE logic are in stored procedures. I've built an entity framework model with mappings to these procedures. In spUpdate I return the new timestamp column so the EF could detect concurrency conflicts. It works fine. I have a problem with the spDelete because I don't see mappings for return values in the "delete function" row. How to check concurrency in this example?

• Unit Test json output in Zend Framework

  - by lyle

  The Zend Tutorial lists many assertions to check the output generated by a request. http://framework.zend.com/manual/en/zend.test.phpunit.html But they all seem to assume that the output is html. I need to test json output instead. Are there any assertions helpful to check json, or is there at least a generic way to make assertions against the output? Anything that doesn't rely on the request outputting html?

• Can Entity Framework model be passed a SQL script to be run against the database
