MVVM Survey results and feedback!

First of all, thanks to everyone who participated in my MVVM survey. Your feedback will influence my decisions!

Here are the Results:

693 Views resulting in 159 completed surveys. (22.9%)


I created 4 different links (my Blog, DelphiPraxis (german only), Twitter and Facebook. The main difference is the View/Fill out ratio.

Facebook : 32,4% // Best of 4 - Thanx
DelphiPraxis : 30,6% // not bad! Danke an meine Leser!
Twitter: 16,5% // I still have no clue why anybody is writing here
This blog: 14,6% // Hey my friend's - you are already reading here!

Perhaps I have to add DelphiPraxis and my blog because some got the RSS-Feed link!


Do you already separate your logic and your UI  with (MVP, MVC or MVVM)

58 from 159 would like to separate logic and UI.
66 already using some kind of separation. // more than I expected

Interfaces?

14 from 159 answered: Don't want to learn how to... // Strange
104 had no problems with interfaces.
41 want to learn how to work with interfaces. // Should I do a Youtube Video for this topic? 

Please leave a comment!

Attributes?

48 of 155 never used
78 of 155 knows how to use
57 of 155 already implemented own Attributes // Good
12 of 155 dislike Attributes in the source code // Ohh... Please give it a try  

Generics?

19 of 159 never used
8 of 159 dislikes generics

If I would use an MVVM-Framework it has to

- match the C# tutorials (12,6%)   // Sorry this won't happen
- work save and fast! (42 %) // Thanx you are my target group
- be freeware (38%) // Sorry this will not be free
- work with VCL (73,3%) // OK, I will implement this too *grumpf*
- work with FMX (50%) // Main target - of course it will work with FMX
- on all platforms (50,6 %) // Of course... With and without ARC I hope for 10.4

If the MVVM framework is not free/opensource what is the chance you would spend money to buy it?



How much would you spend for a Delphi-MVVM-Framework


less than 100€ (58,8%) // For so much work it's a little to low (perhaps as early Bird)
100€-199€ (24%) // Maybe
200€-299€ (8,5%) // It's a good prize
300€-399€ (2,1%) // Good news it would be less
more than 400€ (6,3%) // Thanx, but I think for this price it's unsaleable

Remember it would be with free updates for one year.

How old are you?


How long have you been developing with Pascal/Delphi?


Mark all your Delphi Versions you are still using.


29% are using a Delphi-Version older than Delphi 2007 // Wow why?
14,7% still using 2007 // Welcome in the non Unicode migration club
31,8% Delphi 2009-XE9 // Please update at least to Seattle
12,1% Seattle // OK
24,2% Berlin // Better
41,4% Tokyo // Very good!
70% Rio // NICE!


So far so good, thanx again and leave a comment or give me a call if you want more information!
