The Syncfusion native Blazor components library offers 70+ UI and Data Viz web controls that are responsive and lightweight for building modern web apps.
.NET PDF framework is a high-performance and comprehensive library used to create, read, merge, split, secure, edit, view, and review PDF files in C#/VB.NET.
I've changed XlsIO and Compression libraries today. But when my code call ExcelEngine.Excel.Workbooks.Open() asynchronously, InvalidOperationException("Invalid cross-thread access") occurs. Doesn't the lastest version XlsIO library support asynchronous call?
Sorry the exception type is UnauthorizedAccessException, not InvalidOperationException.
