In Entity Framework Core, there is no direct equivalent to the NOLOCK hint in SQL. The NOLOCK hint is used in SQL Server to allow a SELECT statement to read a table without acquiring a shared lock, and it can be used to improve query performance in certain scenarios.
Get Distinct Object by Id and Return Full Object with C# and EF
If you’re using Entity Framework Core in C# and you want to retrieve distinct items based on a specific property (e.g., ID) but still return the full object, you can use the GroupBy method along with First or FirstOrDefault. Here’s an example assuming you have a class named YourEntity with a property named Id:

Subscribe to EventStore catch-up subscription from the start with C# example
EventStore is an open-source database technology designed for storing, retrieving, and querying event data using a stream-based approach. In EventStore, a catch-up subscription is used to read events from a given point in a stream and catch up to the most recent events. When starting a catch-up subscription, you can specify the starting position using an event number or position. However, in some cases, you might want to start from the beginning or the very first event. Here’s how you can achieve that:
