ASP .NET Core Best Practices 💡
#dotnet
Nice article providing guidelines from Microsoft for maximizing performance and reliability of ASP .NET Core apps.
Which of these techniques are you using in your apps right now?
Link in 2nd tweet below.
Carlos dos Santos retweeted
EF Core has many amazing features.
The highlight?
I think it's the bulk update APIs:
- ExecuteUpdate
- ExecuteDelete
Why should you care?
Performance.
You can write optimal UPDATE and DELETE queries.
Here's how: milanjovanovic.tech/blog/how…
Did you try out these new methods?

Entity Framework Filtered Include example ⬇️
#dotnet
Using Include() is super common to eager load our child navigation collections, it's default usage however could potentially result in a lot of unnecessary data coming back, particularly in systems which deal with large volumes of data.
Thankfully Entity Framework allows us to filter (and sort) our Includes() as the simple example below shows.
Do you use filtered Includes() much?

How to set Entity Framework Batch size ⬇️
#dotnet
Default batch size for SQL Server is 42, this means if you're inserting 100 records, EF will issue three roundtrips.
Roundtrips are expensive so we can try experimenting with the batch size as a performance and latency optimization technique.
There’s a lot of factors at play though so its really a matter of trial and error to see what performs best. Setting the batch size too low will result in too many roundtrips whereas if it's too high there will be less roundtrips but performance could still be poor as the larger query will take more time to run on the DB server.
