I am getting this issue (The type initializer for 'sprន' threw an exception.) while executing below line.

Spire.Xls.Workbook workbook = new Workbook();

I am using Spire.Xls 9.1.0 in C# dotnetcore 2.0.

Thanks for your inquiry.
Sorry that our Spire.XLS does not support working with .NET Core at present.
Our Dev team are working on it and we plan to release it in March 2019. If it is available, we will let you know.
