I have forked the Family show project from CodePlex, WPF in C#
This is a genealogy application
Here is an example:
How to use this application:
Go to the Release page:
https://github.com/fredatgithub/FamilyShow/releases
Download FamilyShow-Release-V3.4.zip file
Unzip it in a folder in your documents or wherever you want.
Go inside this folder and double-click on FamilyShow.exe
Click on the New menu
Add a first member of a family (e.g. you)
Add other persons of your family.
You can also download a sample family
Go to the Sample Windsor Familly section between V3.0 and V3.1 in the Release page
Download the file: Family.Show-samplesWindsor_familly.zip
Unzip it to your folder
With the application, open this file: Windsor.family
Now you can see the Windsor family and add royal members if you like.
