I’m using Microsoft.Reporting.Webforms version 10 in order to parse an RDLC file and produce a PDF. The RDLC is a simple invoice with a couple of embedded expressions.
When I run the application I get an exception that a call to the obsoleted SecurityAction.RequestMinimum has been made when compiling the expressions.
Is this a known bug or something I can remedy?
An unexpected error occurred while compiling expressions. Native
compiler return value: ‘[BC40000] ‘RequestMinimum’ is obsolete:
‘Assembly level declarative security is obsolete and is no longer
enforced by the CLR by default. See
http://go.microsoft.com/fwlink/?LinkID=155570 for more
information.’.’.at Microsoft.Reporting.ReportCompiler.CompileReport(ICatalogItemContext
context, Byte[] reportDefinition, Boolean
generateExpressionHostWithRefusedPermissions, ControlSnapshot&
snapshot)

I also had this issue and by me it turned out that when there is a syntax error in an expression it displayed this error.
