Looking for a sample or tutorial for the new OData bits

Question

I want to write an Odata 4 compliant C# isolated mode serverless function endpoint. I am confused by the recent announcements here about ASP.NET Core OData 9 and OData .NET 8 - which should use?

Are there any tutorials or samples for this? All I can find are materials abour earlier versions.

Answer 1

Hi @Gil Shalit,

If your project target framework is under .NET 8, you could only use Odata 8 in ASP.NET Core.

Tutorials you could refer to: ASP.NET Core OData 8.

If your project target framework is .NET 8 or later, you could consider using Odata 9.

For Odata 9 you could refer to ASP.NET Core Odata 9 .

odata 8/9 is more about compatibility with changes in the .net runtime rather than new features. you should do fine with the current documentation. the release give breaking changes:

https://learn.microsoft.com/en-us/odata/changelog/odatalib-8x

odata 8 has the latest features and supports earlier version of .net core (back to 3.1). Odata 9 has been updated to require all dependencies to be at least version 8 runtime, so .net 8 runtime is lowest supported.

for new code, as runtimes before .net 8 are out if support, you should pick .net 8 or .net 9 runtime for your functions. Therefore pick odata 9.

note: .net 8 is the LTS version supported to 11/10/2026. .net 9 is a standard (1 year support) is supported to 5/16/2026.
