MarcelloDB is an embedded NoSql object-database for Xamarin and UWP (Windows Universal) apps.
MarcelloDB saves plain C# objects, including child objects, lists and dictionaries. Not having to map your objects to the relational model can save you hundreds of lines of code.
It's a pure C# implementation, no need to package other binaries.
#Documentation Read the docs here: http://www.marcellodb.org
#Current Status Current version is 1.0.1.
Although it's the first version, the community has been testing beta versions since october 2015. It is allready really stable. This version is backwards compatible with 0.6.
###Upgrading to 0.4 There are a few breaking changes from 0.3 to 0.4, read about them here
###Upgrading to 0.5 Code compatible with 0.4 is expected to compile and run without modifications with 0.5.
Data from 0.4 remains readable, but existing indexes are no longer readable so they will have to be rebuilt.
Copying all objects to a new collection will do the trick. It is even better to copy the data to a new collection-file and delete the previous one to save space.
###Upgrading to 0.6 Code compatible with 0.5 is expected to compile and run without modifications with 0.6.
###Installation
