I am trying hard to find any geospatial library that supports .NET Core, however with no success so far. Do you have tips for any?
My requirements are:
I believe that NTS, The .NET Topology Suite contains code capable of doing geometry operations on GIS structures. It's a .NET port of JTS.
Install OpenJUMP and study what all has been gathered into it
I have never really understood what all the alternatives are. ImageIO-ext is probably utilising native GDAL binaries if such are available but at least most other alternatives are pure java. There is also one more alternative in OpenJUMP called "Sextante raster" which is also pure java. Different drivers understand different tiff variants. Make a test data set with different compressions and try what works and what not. Sometimes the tiff needs to be geotiff with valid georeferencing, sometimes .tfw is enough and sometimes even an ungeoreferenced tiff opens.
GeoTools and GeoServer for sure can deal at least with some tiff variants without the ImageIO-ext extension. Install GeoServer without extensions and create new GeoTIFF raster stores from different tiffs and you will know what works and what not with GeoTools.

I ended up using NetTopologySuite. This library is used internally by Entity Framework Core for spatial operations.
