Microsoft XNA is a set of tools with a managed runtime environment provided by Microsoft that facilitates video game development and management. XNA attempts to free game developers from writing "repetitive boilerplate code" and to bring different aspects of game production into a single system.

The XNA toolset was announced March 24, 2004, at the Game Developers Conference in San Jose, California. A first Community Technology Preview of XNA Build was released on March 14, 2006. XNA Game Studio 2.0 was released in December 2007, followed by XNA Game Studio 3.0 on October 30, 2008. XNA Game Studio 4.0 was released on September 16, 2010 along with the Windows Phone 7 Development Tools.

XNA currently encompasses Microsoft's entire Game Development Sections, including the standard Xbox Development Kit and XNA Game Studio.

The name "XNA" originated out of the project's development name, Xbox New Architecture. Instead of being released under the Xbox name, the Xbox 360 was released (2005), and XNA came to stand for "XNA's Not Acronymed".

Imagine Earth – Steam full release date revealed

Global real-time civiliation sim Imagine Earth finally has a Steam release date along with a massive update.Big News Space Colony Managers,
It’s been a long lasting journey of over seven years through the hyperspace of Early Access for Imagine Earth – Planetary Colonization. Our global real-time civilization sim Imagine Earth finally has an official Steam release date and will be delivered with a massive “world congress” update PC on 25th May.

Release trailer

Thank you all for making this possible

Some of you have been following our project for ages, popping in every few years, and some are new to it, having only recently joined our quest for new, habitable worlds. Over all these years, the game has found over 43,000 supporters who have made the development of our world simulator possible until today. Check it out on Steam.

Beta Test for Release Feature

In the next few days we will be making available a beta version of a new feature we are currently working on. If you would like to participate in this beta, please join our Discord server: Discord.com.

Open Space Addon

In parallel, we have already started planning and producing an addon in which you will be able to colonize procedural galaxies and the exchange of goods and commodities between planets will be strengthened. It will also be possible to upgrade your own space base and equip the settlement capsules with special properties.

Early Access Recap Post

To celebrate this important milestone, we will write a comprehensive summary of all the events and developments during that time. It’s going to be a turbulent journey through time.

Community Survey

Over the time of development, we have accumulated a long list of good ideas that we think would be great additions to the game. However, we want to get your opinion and wishes on how best to improve the game. Get ready for a big poll around the release.

Here you’ll find the official press release. Here is the release post on Twitter from you afterwards we’d be happy if you would push it with likes and retweets.

I have uploaded some open-source XNA 4.0 projects on my downloads page here: Indiedb.com

I will be uploading more projects there later over time. Happy Coding :-D

Finally! MonoGame is coming to Xbox One. MonoGame implements XNA 4.0 and allows developers to port their games to other platforms besides the default platforms supported already by the XNA 4.0 Framework. Link: Twitter.com

Also, I need to correct myself on an older post. Unity has Mono built into it, not MonoGame. So if you are eager to finish your XNA game, with some work, it is possible to import your XNA or MonoGame project into Unity. Mono is a cross-platform open source implementation of Microsoft's .NET Framework. It is based on the ECMA standards for C# and the Common Language Runtime.

With MonoGame 3.4 (which is the continuation of XNA 4.0) for Visual Studio 2015, it is now possible to create a game for Universal Windows Platform (UWP). This also makes it possible to get your XNA project to run on Windows 10 with UWP. Since the Xbox One dev kit supports UWP, it might also be possible to get a MonoGame project running on it.

If anyone is curious, it is possible to integrate your XNA Game Project into Unity, but it might take a little extra work. This is a proof of concept showing the Platformer XNA starter kit running inside Unity3D. Zero code changes have been made to the original game code. Using a mixture of new code and some code from MonoGame, the author has implemented XNA emulation. They did so by having a game object with a script attached run an XNA game performing updates and drawing.

Check out this link below for the source code:

Interesting but what about the performance? I persume it would drop radically under such conditions.

My apologies for replying back so late. Under such conditions, it is possible for the frame-rate to drop. By performance, are you referring to graphics specifically? I sometimes rarely hear people speak of physics performance or audio performance. Honestly it depends how the XNA game was coded prior to being imported into Unity. It would be best to fix garbage collection issues in your XNA game project before importing it into Unity. There are many ways to help increase performance in your XNA project prior to importing it into Unity. Its a question of whether or not you are CPU or GPU bound. Using the CLR Profiler can help you find out. Things like changing foreach loops to for, multi-threading, using StringBuilder instead of String, and using DrawUserPrimitives are just some ways to help the frame-rate. In my game constructor, I set the following to false: IsFixedTimeStep = false; and graphics.Synchr

(Sorry for the double post. I didn't realize that I was logged out)

No problem. Yes, I was referring to the graphics performance.
You mentioned DrawUserPrimitives(). So far I have only used it in 3D with Vector3. Do you use DrawUserPrimitives in 2D as well? If so are you still using a Vector3 and just projecting 3D data on an orthographic view? Do you know if vector2 can be used with vertecies and triangles?
Thanks.

For drawing primitives in 2D, you really just need to know what to tell the system to make it work. Check out this great tutorial for more information. I hope it will further answer your questions as it has helped me.

I checked the link you posted, after seeing it I remembered that I checked the same blog long ago (might be a couple of years ago). Turns out the author is talking about what I was refering in my comment. Projecting Vector3 vertecies on an orthographic view. It was good to read it again. Thanks a lot for the reply and the link.
Cheers!

It's not an engine, its a framework basically a template to directX. I really like it because it allows you to develop for 3 Microsoft platforms and can port them easily.
