Asked On January 2, 2020 08:23 PM UTC

I currently use the Syncfusion XLSIO, DOCIO, and PDF libraries, and have a license for all of the libraries. I'm trying to use some of the controls, but no matter which Syncfusion control I try, I get this error: "0x800a1391 - Javascript runtime error: '$' is undefined" at runtime. 
What am I missing?

When I run your sample app, I get this error: 

Could not find a part of the path 'C:\SyncfusionControlSample\WebApplication1\bin\roslyn\csc.exe'.
