I program with visual studio : vb.net, c#, asp.net and RPG.
I want to develop a new application like a calendar which must run on : mobile, tablet , web.
The database can be Sql Server or DB2 (depending on the customer).
I have been reading a lot of articles about: telerik, xamarin, ibm worklight, trying to decide the right technology.
First choice: ibm worklight. Maybe because I don't know so much about java and eclipse, but I didn't understand how it works. It's a very complex configuration and a mix of plugins put together. The benefits about worklight is that it has an hybrid project (android, iOS and web) which even connect easely to DB2. Although I didn't understand if I could develop iOS project without Mac. In few words too complex.
Second choice: because the DB is so different, I thought that WCF was the right technology for the connection with DB with Visual Studio and Xamarin. I think the integration with VS is too expensive. I didn't try it at all.
Third choice : then I saw visual studio 2013 with the Telerik plugin and it's AppBuilder project. I just took a look, but I didn't see a designer. It seems it must be made all by HTML 5.
Eventually I got lost !!!!
Maybe I haven't seen other possible platform. Before I take a choice I want to be sure I evaluated all the products on the market.
Has anybody developed a software on so many platforms ?
Has anybody on a technology I wrote above ?
Can anybody suggest me or give me a hint about the best technology to use ?
Thanks in advance.
