Migrate to new aspnet core version.

[GustavoFonsecaDeAlmeida]

Today i was make a plan to migrate to new version but a with out a authetication i cant do it. I Will stay using this version and making PR to implement new features to help me and others.. I Will work to make the Change in both projects.

My next steps :

• a way to configure a internal DB connection string ( BeatPulse ui) using appsettings or other way

• Plan a way to improve notification for each resource or group of then and keep a possibility to make one for all.

• explore the down notification and liviness results to make a easy way to make a history.. Maybe create one resource at ui to this too ( Im learning react to do it..)

Thanks @CarlosLanderas to create a issue to Microsoft and @unaizorrilla
