  MIME types missing in Azure WebSites A MIME type is a two-part identifier for file formats and format contents transmitted on the Internet. It consists of a type, a sub-type and optional parameters. When publishing a new website in Azure WebSites, you may find out that not all file types can be served without some prior configuration. For example, if your site needs to serve custom fonts, either for icons...... 16-03-2016, 12:39 από Paris Polyzos στο Paris Polyzos - a developer's notebook Δημοσίευση στην κατηγορία: azure, Notes

  Passing multiple models to a view using Tuples in an ASP.Net MVC 5.0 application This is the second post in a series of posts regarding passing multiple models in a view.You can find the first one here We do know that in any MVC application we cannot pass multiple models from a controller to a single view. In this post I will provide you with a workaround for passing multiple models in a single view in MVC. In object-oriented and functional programming, an immutable object is an object whose state cannot be modified after it is created. A Tuple object is an immutable, fixed-size and ordered sequence object. It is a data structure that has a specific number and sequence of elements. The .NET framework supports tuples up to seven elements. Strings and other concrete objects are typically expressed as immutable objects to improve readability and runtime efficiency in object-oriented programming. I am going to use EF as my data access layer. More specifically I will use the Database First approach in EF. Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.

  Passing multiple models to a view in an ASP.Net MVC 5.0 application We do know that in any MVC applicatin we cannot pass multiple models from a controller to a single view. In this post I will provide you with a workaround for passing multiple models in a single view in MVC. There are several approaches to achieve this but I will use the List<object> and the object object. I am going to use EF as my data access layer. More specifically I will use the Database First approach in EF. Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework. EF addresses the problem of Object-relational impedance mismatch . I will not be talking about that mismatch because it is well documented in many sites on the Internet. Through that framework we can program against a conceptual application model instead of programming directly against a relational schema-model . 1) I will create an empty ASP.Net Application (Empty MVC applicatin) and I give it the name . I am using Visual Studio 2015 Enterprise edition, C# 5.0 and EF 5.0 version. 2) I will use the AdventureWorksLT2012... 06-03-2016, 16:23 από Nikolaos Kantzelis ASP.Net Blog στο Dot Net Rules Δημοσίευση στην κατηγορία: asp.net, asp.net mvc 5.0, Entity framework, visual studio 2015

  Custom Validation Attribute to validate when a collection is null or empty A custom validation attribute allows you to create metadata, that you can use in the data model to validate data fields. In order to validate when a collection is null or empty, you may create a custom validation attribute, which returns false in case the object is null or empty. [crayon-56d4b8aa38fbd868986865/] You can now decorate classes using this attribute, i.e.: [crayon-56d4b8aa38ff3854591558/] Let’s assume that you have a WebAPI method test/validation, which:...... 29-02-2016, 23:31 από Paris Polyzos στο Paris Polyzos - a developer's notebook Δημοσίευση στην κατηγορία: c#, Snippets

  Handling concurrency in Code First ASP.Net 5.0 MVC applications In this post I am going to provide you with a hands on example on how to handle concurrency in an EF Code First ASP.Net MVC 5.0 application. Basically I want to show you how to handle conflicts when multiple users update the same entity at the same time . You can find another post regarding concurrency with EF Database First and web forms here . When we are talking about concurrency in an application where EF acts as the data access layer, our main focus is how to make sure that the integrity of the data in the database is ensured in a multi user connected environment . Databases are very good in managing concurrent users. All the objects/entities are retrieved from the datastore into the memory. The changes we make are applied in the memory and then we flush the changes to the database. But what happens if those entities have been changed from another user in the time it took us to update them in memory?Well someone will say, "Dude, you just have to use pessimistic concurrency and your problems are solved." Well,... 29-02-2016, 02:10 από Nikolaos Kantzelis ASP.Net Blog στο Dot Net Rules

  Caching an ASP.Net MVC 5.0 application In this post I am going to provide you with a hands on example on using caching in an ASP.Net MVC 5.0 application using Visual Studio 2015 and C# . More particularly I'll show you how to use the underlying ASP.net caching engine to improve the performance of an application. There is a number of different cache settings you can use.These settings are all available from the underlying ASP.net cache engine. It's the same engine that Web Forms uses. It's not something that's specific to just the MVC framework. But first things first. What is caching why do we need caching in the first place? Caching is of vital significance in any high-performance web application. Caching provides a way of storing frequently accessed data and reusing that data . It is an effective way for improving web application’s performance and user experience. The main advantages of caching include: Reduce network traffic - Content is cached at the client side, thus reducing network traffic Reduce database server round trips -Content that... 28-02-2016, 20:46 από Nikolaos Kantzelis ASP.Net Blog στο Dot Net Rules
