VSTO

Why

So, why VSTO here in an OpenSource themed wiki?

1. since 2015 .NET is opensource (really)
2. C# ist open source
3. you can get the Visual Studio Comunity Edition for free (really free also for commercial use, if you are not working for a > 250 men company)
4. Word an Excel are running fine with wine (see #MSOffice_2010_and_Wine) - Outlook not tested yet,

In most cases Word, Excel and Powerpoint are the most often used programs in business for daily communication. It is like it is. Beeing able - now - without any restrictions, to program MS-Office legally also for commercial usage. The only "drawback" is: you HAVE TO register the application and therefore create a microsoft account to be able to work with it.
