Although I'm quite familiar with Mathematica, I always try to keep an open mind and don't use it as golden hammer. I'm particularly good at things that are fun, for instance

comment Graphics3D flickers in Mathematica 10 and Linux
@Ruslan For me, the bug is gone. There is a small flicker when I release the 3D Graphics from the rotation and if snaps into its final form (with antialiasing), but otherwise, it works smooth.

comment How to get the digits after the decimal point
I would be helpful if you could add what you want to do with the result. Do you need an integer like 4142136 or a string "4142136" or is a list like your last output OK?

Please read carefully the instructions here in the WSTP documentation.

Note, I'm not a windows guy! But it seems that you don't have configured your project correctly. AddTwo is a simple console application and as it looks, the project you created is not a console application. You can change that in the solution settings somewhere. Can you check that?

My first intention would be to use the dependency walker on the created executable and see what it shows you about the library that is missing.

Even without a discussion of DynamicModule this answer is very well written. Thanks. If you find the time to include your opinion about the statement in this comment, it would be very nice.

comment Context of localised (dynamic) symbols
@Mr.Wizard I have linked this very article in the beginning. Especially because of your first sentence "Symbols are created in the current context" which is not quite correct if I understand it as you intended it. That's why I almost quoted you.

comment Context of localised (dynamic) symbols
@LeonidShifrin One question that persists is: Why isn't DynamicModule forcing every symbol into the $CellContex? This context is not in the search path and name clashes are not possible. I mean, it does it for all Global` symbols. Why not for the rest?

comment Context of localised (dynamic) symbols
My assumption (haven't added it to the question) was similar. Since Module[{x},..] creates an entry in the symbol table for x even if it uses then x$123, it would lead to name clashes when it creates it in the global context and another x lives in another accessible context.

comment FindFit runs extremely slow for my Function,how do I optimize this?
@OleksandrR. This is awesome. With your setting you can remove the MaxIteration option and increase the sum-sampling to 1000 and the algorithm finishes after 336 steps (or about 60 seconds) with a very exact parameter fit! (worked it into the answer, thanks)

@OleksandrR. Ah, haven't seen that but I was really surprised that so many evaluation steps are necessary. In fact, I had hoped you answer somethings since I knew you did a lot of work with NMinimize.

comment Plot Plane to Intersect 3D Contour Plot in Mathematica
Well, just do it the other way around to close the heart: Use the heart expression of RegionFunction and draw a parametric plane. Please look at the other styling options like BoundaryStyle too.
