I have local database where I insert some data and I want this data to be available also in cloud. As a lazy guy I don’t want to synchronize data manually. After setting up local and cloud databases I activated Azure Data Sync to just find out that it conflicts with EF7 insert and update queries. As I don’t have many tables and my database is pretty small I invented simple workaround.

In this blog post I will show you how to create authorization attribute that you can use to make authenticated users insert their access code if it is their first visit to site.

In my posting about Entity Framework 4.0 and POCOs I introduced lazy loading in EF applications. EF uses proxy classes for lazy loading and this means we have new types that come and go dynamically in runtime. We don’t have these types available when we write code but we cannot forget that EF may expect us to use dynamically generated types. In this posting I will give you simple hint how to use correct types in your code.
