RazorEngine System.OutOfMemoryException #77

Open pacharbit opened 1 year ago

pacharbit commented 1 year ago

Hi, I have a problem when generating reports with SealLibrary. Compiling Razor views seems to be a problem (see below). Our architecture:

an API project (.Net6), that implements an in-house report generation project ("ReportBuilder" ) (.Net6), that implements a generic in-house reportbuilder package ("Net.Report.Builder") (.Net6), which integrates SealReportLibrary.NETCore 6.7.2.

When we execute directly the ReportBuilder project in debug mode from VS (or call the ReportBuilder.exe via cmd), the reports are well generated. Do you have an idea ? Many thanks for your help. Pierre

Check that your report models do not return a huge amount of data. Normally 10'000 rows is a certain limit, it has no sense to return more data.
