IdentityServer4.Contrib.LiteDB

Reference

IdentityServer4.Contrib.MongoDB
This project is about 99% the same as the MongoDB variant. LiteDB is MongoDB friendly, so it was basically a search and replace "MongoDB" => "LiteDB"

Usage

Startup

    Configuration["liteDb:ConnectionString"] = Path.Combine(liteDBPath, "IdentityServer4.liteDB");
}
