Cant find much documentation on how to use NetTopologySuite with Entity Core. Looking for stuff like
Inserting a Poligon suing Entity Core Classes and NetTopologySuite, Inserting a Location Point using Enity Core with NetTopologySuite datatypes/property.

Links to any documentation on CRUD operations using Enitity Core/NetTopologySuite will be great.

Was looking for examples of CRUD operations to geography type columns .

Inserting a new row using (entity core/nettopologysuite) in DB with a Geography column type that will store a Polygon ? or Even inserting a new row in the DB with column (geography) storing location pount?

Have also checked http://www.npgsql.org/efcore/mapping/nts.html not much info there either.

Ditto. I am converting .NET Framework v4.8/EF code with a DbGeography data type to .NET Core/EF Core 2.2, and am getting a "cannot bind 'spatialServices', 'spatialProviderValue' in DbGeography(DbSpatialServices, object spatialProviderValue)" exception when I am trying to use this POCO. Cannot find good examples that use the DbGeography type as a column in the new Core.

@Kurtbaby DbGeography and DbGeometry are specific to EF6. They cannot be used with EF Core. The NTS types are essentially replacements for these types.
