I have recently installed reporting onto my machine. All the example projects works fine but the below one is not loading the report fine and throws exception. 

CSharp.Asp.NetCoreDemo

 

Unable to get report parameters.
An error has occurred.
Unable to establish a connection to the database. Please, verify that your connection string is valid. In case you use a named connection string from the application configuration file, make sure the name is correct and the connection string settings are present in the configuration file of your application.

It looks like all the reports which connects to DB with .NetCore is not working. 

 

Can you fix and let me know what is the issue? 

Hi Senthil,

Thank you for reporting this issue, we managed to reproduce it on our side. It seems that the connection string is not saved correctly in the configuration file of the .NET Core demo project during the installation of Telerik Reporting.
We will log it into our system for further investigation and improvements. Your Telerik points were updated to thank you for bringing this issue to our attention.

In order to run the project, change the connection string in application configuration file. In .NET Core projects, Reporting engine will look in the project's root app.config for any named connection strings.
  

Regards,
Katia
