Configuring form based authentication in SharePoint 2019 on windows server 2022. I am getting this error while adding providers in the IIS for SharePoint site.


thank you

Finally I have done it via web.config

Added the below code in In the <roleManager><providers> section 


<add name="FBARoleProvider" connectionStringName="FBADB" applicationName="/"
 type="System.Web.Security.SqlRoleProvider, System.Web, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

FBADB = your connectionStringName
