SSRS Integrated Mode Issue Microsoft.ReportingServices.Alerting.ServiceContract
Exception: System.Reflection.
After very long time I had to patch my SharePoint farm and
during the UAT I was facing this issue.
Unfortunately this was the first time I ever faced this issue
and it took me pretty good time to find the solution.
If you also have a SharePoint farm with SSRS Integrated mode
and Report Viewer Web Part Deployed to your farm, then you might face this
issue.
Issue:
After successful installation of Binaries of SharePoint 2013 CU
March 2019 Every time when Product Configuration wizard executed on the Server,
I got this error in PSDiagonstic
Error Log

Resolution
This is caused by the WSP solution related to the Report
Viewer Web part and Microsoft has warned regarding the same.
And resolution suggested in this article (https://docs.microsoft.com/en-
1.
Remove the Report Viewer web part
2.
Uninstall SSRS
3.
Reinstall the Report Viewer web part
In my scenario our BI Team was not using
this web part in UAT farm, hence I simply uninstall and remove the farm
solution from the SharePoint Farm.
Problem Solved, Next time PSConfig
executed like a charm.
Cheers
