ASP.NET Core Crystal Reports integration

Question

I developed a web application using ASP.NET webforms technology and it contains lots of reports designed by Crystal Reports.

I want to convert my project to ASP.NET Core technology, but I have a problem that's ASP.NET Core does not support Crystal Reports. I searched Google for any help, but did not find any.

I have almost 300 reports. Can you please suggest how to integrate these Crystal Reports with an ASP.NET Core web application?

Answer 1

You probably need a Standard classlib project that reference to a .NET Framework classlib project that uses Crystal Reports.

The ASP.NET Core project can use it as proxy to use the Crystal Reports in the .NET Framework project with the Core project setting reference to the Standard project.

Answer 2

Crystal Reports does not support .net core, .net 5 or 6, and does not have any immediate plans to support .net core. They offer a couple solutions:

1) switch to java
2) hosts the reports it a 4.8 web application, and reverse proxy to it from you asp.net core application.

option 2 is probably your best.

note: .net core applications, nor .net standard libraries, can not call a 4.8 dll.

Answer 3

I published a tutorial to render Crystal Report in PDF using ASP.NET Framework 4.7/WebAPI 2. The PDF is accessible via REST API so client such as Angular 12 can get to it. Source code is included. Crystal Report to PDF Viewing with Angular and Asp.Net WebAPI
