Hi,

we've been using Stimulsoft with ASP.NET MVC for years. After migrating to the ASP.NET Core version (on .NET Framework), however, conditional expressions with string.IsNullOrEmpty don't work anymore.

Examples:

This expression worked before, but doesn't work anymore:

Code: Select all

{(string.IsNullOrEmpty(Parameters.Location.Uri)) ? "unknown" : Parameters.Location.Uri}

The condition always returns FALSE.

This still works:

Code: Select all

{(Parameters.Location.Uri == null || Parameters.Location.Uri == "") ? "unknown" : Parameters.Location.Uri}

The condition works correctly.

Any ideas what causes this?

Thanks in advance.
