If you see this post it means that BlogEngine.NET is running and the hard part of creating your own blog is done. There is only a few things left to do.

Write Permissions

To be able to log in, write posts and customize blog, you need to enable write permissions on the App_Data and Custom folders. If your blog is hosted at a hosting provider, you can either log into your account’s admin page or call the support.

If you wish to use a database to store your blog data, we still encourage you to enable this write access for an images you may wish to store for your blog posts.  If you are interested in using Microsoft SQL Server, MySQL, SQL CE, or other databases, please see the BlogEngine docs to get started.

Security

When you`ve got write permissions set, you need to change the username and password. Find the sign-in link located either at the bottom or top of the page depending on your current theme and click it. Now enter "admin" in both the username and password fields and click the button. You will now see an admin menu appear. It has a link to the "Users" admin page. From there you can change password, create new users and set roles and permissions. Passwords are hashed by default so you better configure email in settings for password recovery to work or learn how to do it manually.

Configuration and Profile

Now that you have your blog secured, take a look through the settings and give your new blog a title.  BlogEngine.NET is set up to take full advantage of many semantic formats and technologies such as FOAF, SIOC and APML. It means that the content stored in your BlogEngine.NET installation will be fully portable and auto-discoverable.  Be sure to fill in your author profile to take better advantage of this.

Themes and Plugins

One last thing to consider is customizing the look and behavior of your blog. We have themes and plugins available right out of the box. You can install more right from admin panel under Custom.

On the web

You can find news about BlogEngine.NET on the official website. For tutorials, documentation, tips and tricks visit our docs site. The ongoing development of BlogEngine.NET can be followed at Github. You can also subscribe to our Youtube channel.

Good luck and happy writing.

Make strong object references cache default in SessionNoServer constructor and switch to weak object reference cache when memory available is low, switch back to strong references when more memory is available.

Rerun benchmark on a slightly faster PC, looks great! This time with compression turned on.

Enable strong object reference cache with ServerClientSession constructor.

By default, strong references are now used instead of weak references.

A client test case ran more 1000 times faster with this option. Caching is improved.

Replace a Queue with a RingBuffer (as in Ndisruptor) in server request management.

Use BufferedStream for network writes to reduce networks packets

Fix a recursive issue in recovery

Add databasePerType parameter (default == true) to SessionBase.AllObjects for faster lookups

foreach (var obj in session.AllObjects<DomainObject>().Take(10))

Console.WriteLine("id: {0}, products: {1}, likes: {2}, comments: {3}", obj.Id, obj.Products.Count, obj.Likes.Count, obj.Comments.Count);

If you have a lot of different types of objects and many of each, this option will make it fast to find a certain type of object. Otherwise we have to examine each page in every database in order to find all objects of a certain type. If you use this option (on by default) you must persist your objects using the recommended Persist API, i.e.

var look = new DomainObject(session, i);

We changed TcpClient.NoDelay = true to speed up client/server communication.

World Cities sample: Now with an associative click interface

Sample:

AllObjects<NotSharingPage> all = db.AllObjects<NotSharingPage>();

List<NotSharingPage> notSharingPageList = all.Skip(100).ToList();
