Hi teebeeno,
Thanks for your inquiry. This is Amber from E-iceblue support team.
Kindly note that we don't remove the functions for .NetStandard or .NetCore.
On our website, now the latest version is
Spire.XLS Pack Version:9.7, after installing it, you will find the dlls in the folder "XXX\Spire.Xls\Bin\netstandard2.0".
On NuGet, we changed the folder ".NETStandard 2.0" to the folder ".NETCoreApp 2.0" to place those dlls. And the folder ".NETStandard 2.0" will be used for placing the dlls which could work with Azure Function. Once the dlls for Azure Function is implemented, we will put them in the folder ".NETStandard 2.0" on NuGet ASAP.
If the target of your framework is .NET Standard, you cannot install the Spire.XLS via NuGet. There would be an error. In this case, I suggest you download Spire.XLS from our website. Then manually reference the .NET standard dlls from the folder "netstandard2.0". And install the dependency dlls(System.Drawing.Common and System.Text.Encoding.CodePages) in your project.
Any question, welcome to contact to us.
Best wishes,
Amber
