    Hi Roop,

    v2.8 is release can you try with the latest version. If the issue has not been resolved, write your project creation details. tier architecture? mvc / angular? send your suite project create screenshot.

    Was able to resolve, Alper. Looks like while first time setting up project .dbMigrator project has to be run. Shouldn't be using Package Manager Console. as dataseed didn't happen, I saw above error while launching IdentityServer module. Can be closed now. Thanks.

    DbMigrator, creates the database, applies migrations and seeds data. Good to hear it works.
