In this post I am going to present my solution for handling optimistic concurrency scenarios in Entity Framework. This solution is somehow an extension of recommended approaches presented on MSDN Entity Framework learning center here.
By Mirek on (tags: database concurrency, Entity Framework, categories: code)A time ago I have been writing about the Sql Server application roles, what are the benefits of using them and what are the limitations when we want to incorporate the Entity Framework to use application role. Today I will show you how to workaround those limitations with new Entity Framework facility introduced in version 6 of the framework.

It has led to an exception with a confusing message “Could not determine storage version; a valid storage connection or a version hint is required.” Thankfully I have solved this issue finally.

It is open source and free for use, but as many of free things is not super user friendly. The creation of the installer is XML based. In this post I will try to present a kind of boilerplate template which you can use to quickly create most of the need installer.

You can add element to the xml document tree and the application should not crash or fail while consuming this xml. This is what we can read on the w3schools.com xml tutorial. But how is this with serialization of the xml?
By Mirek on (tags: Version Tolerant Serialization, XML, categories: architecture, code)The XML data type allows storing a xml content in our SQL Server database. The great feature is that we can also attach an XSD schema to it and have the xml content automatically validated. Here I am going to show you how to set it up together with Entity Framework Code First.

It makes you don’t need to worry about the database schema updates almost at all. There are however few things you must know to properly understand and use EF migrations. This post describes few of those things.
