Recently I’ve been working on a api project where the requirement was that any data on the api service side is plain xml, stored in database as xml type column. No binding and object materialization is done on the server. However the client has to operate on clr objects. I am going to show you the solution I came to.

Today I will show you how to workaround those limitations with new Entity Framework facility introduced in version 6 of the framework.

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.

Very often you didn’t know what type the variable is or if it was an object or a function. I always lack of some strong typing, design time rich intellisense or compile time type checking, which would minimize the possibility of making a bug in the java script code.

Here you will see why you should take a special care about the floating point calculations in your software.

It simply grants a access to a program that provides application role credentials, not for the user login that is used to connect to a database.
