I need something to create 3D surface charts in ASP.Net. Could anyone recommend a 3rd party component set? I also do not want to use Giga Soft's, Nevron's, or ComponentOne's components. I am open to non-free solutions.
This is a good question.
I have performed a search/watch for my company few months ago and it is a cruel lack.
Personnaly I would not go for expensive third party solutions as they are seriously overpriced IMHO. Most of them do not give enough interactivity and are full of flourish while lacking the real features that one could expect from a decent 3D Surface.
I've ended up using ILNumerics which is fully open source (and even contributed a bit to the project). It's Winforms, but you could port it to ASP by tweaking a bit.

I suggest Dundas Charting because of its stability and easy to use system
It provide different kinds of charts and work great with / without SQL Server Reporting Services, it has dynamic and static reports so that you user can build his report on the fly with your current reports.

Last day in job I got pretty hard task. My task is to make new theme for our project (website). New theme should be rewritten to be fully responsive (actually it isn't). I have decided to use Bootstrap framework, because it is seems to be pretty nice, easy to learn and have good documentation with examples.
Today after reading most of documentation I tried to implement this. The only problem is that I tried to use it's main Less based version (which seems to have better support, cuz is main) to get better customizable themes (each theme can have it's own variables.less file) and I did not found good Less parser that work with .net MVC3.
Using JS to parse Bootstrap in not an option, because some of our customers have pretty old computers (Windows XP + IE8). I have tried to use dotless as a parser, but it had problems to handle Bootstrap, had problems with relative paths (problem with #include instruction) and was unable to load files from different directories (variables.less is in theme directory when rest of Bootstrap is shared).
If anyone can help me I will be very grateful, cuz today I spent ~8h and did totaly nothing.
You could try http://vswebessentials.com/
This nice Visual Studio plugin support LESS out of the box.

I am looking for some sort of API similar to Photoshop functionality, I need to create an image using layers/masks/filters programmatically.
An example: I know how to make a nice button in Photoshop, there is a sequence of simple actions. What I want is to automate this process and generate an image of the button on the fly with a few input parameters.
I think I am not the first one who came up with such idea, there must be some library out there that does this thing. Unfortunately I cannot find anything.
Thanks!
You failed to mention if the library needs to be free/open source or if commercial libraries are acceptable but one of the best out there is GdPicture.NET. I doubt you'll find anything free that is remotely comprehensive but a good free one is Filters library (LGPL).
i don't think there is an API like this
but there is free open source software which is Paint.net
get it here
http://www.getpaint.net/download.html
see source code here

hope it helped
GDI+ in .NET?
Although I haven't used them you could take a look at:
Emgu CV: http://www.emgu.com/wiki/index.php/Emgu_CV
or OpenCvSharp : http://code.google.com/p/opencvsharp/
ImageMagic have layers support http://www.imagemagick.org/Usage/layers/ and there is Net wrapper

I'm starting a new project in .NET which will require some geometry algorithms, such as:
checking if a point is inside a polygon
bezier curves
line intersections, etc.
I've found some libraries, however, they are paid/expensive, these include:
G# - http://www.ceometric.com/store.html
DigitalRune Geometry - http://www.digitalrune.com/Products/Geometry/Overview.aspx
NLIB - http://www.smlib.com/nlib.html
sgCore - http://www.geometros.com/sgcore/index.htm
These do what I need and much more, which makes me spend too much money on something that won't get used so much.
I've found some open source projects:
MATH.NET
alglib
anti-grain (C# bindings/port)
But these do less than I need, however, they're easy to find when you look on google. After some time searching, I've found this library:
Tektosyne (http://www.kynosarges.de/Tektosyne.html)
Which does most of what I need. It is also free of charge and is provided "AS-IS". Which is good.
However, if you search google for "Tektosyne", you find very few results. So my question is (for those who have experience with some "advanced" usage of geometries in c# of StackOverflow):
Do you have another libraries to recommend or why is this library not "popular"?
Have you looked at this?
github.com/DotSpatial/DotSpatial
Or
NetTopologySuite https://github.com/NetTopologySuite/NetTopologySuite
I assume you're looking for something for WinForms. If you haven't looked into WPF yet, the functionality that you mentioned is all available there. Plus you could always host a WPF Control in a WinForms program.
We are using sgCore in our 3D programs. Beautiful library. We are purchased full sourcescodes - very clear code inside.

Following this question from last year. I am checking two open source ribbon controls:
Fluent
Odyssey
Do you have any experience (good or bad) with any of them? or perhaps know of another open source ribbon control?
Follow up:
After using both of them, I gave up Odyssey cause it had a lot of bugs. I then switched to Fluent and I have only good words to say about it.
I've been trialling the WPF toolkit. Bear in mind - it's not open source per se - you don't get the source code. However, I believe it is free for use etc.
It's reasonably easy to use and has some reasonable commanding support. The documentation is not particularly in-depth, but it looks good - same as the ribbon used in Office 2007 etc. and has a few themes.
I'd say give it a look before spending money on a third party commercial ribbon control.
there is one included in the WPF toolkit dont know how good/bad it it. we use one that we bought.

I want to visualize components and connections of a HVAC system with .NET/C#.
The diagrams will just include a few different components and their connections.
They do not have to comply to any formal standard and should look alike the diagrams attached. In addition the user should be able to select a single component/connection (so that I can display additional data).
Which free drawing/charting library would you use and why?
Thanks for your time.
Julian,
Please check out GraphSharp: http://graphsharp.codeplex.com/Release/ProjectReleases.aspx
Small/open source C# library on Git renders to HTML5 (You can modify to render to for example WPF or Winform as well)
https://gridwizard.wordpress.com/2015/03/25/simple-c-library-to-render-graph-to-flowchart
I would try to host VS studio designer in application , how you can host workflow designer for instance. Read about VS extensibilities
It doesn't get more free than System.Drawing...
Seriously, given your requirements I'm not sure you need a framework or library. The most complex part of the system you describe is drawing the lines between components. If that doesn't have to get fancy (automatic layout, detecting where the lines overlay other lines/boxes) then you can probably roll the whole thing custom.
