Hi @Jingshu923, here have two questions:

• Why you remove the file in src/Extenisons? Do you restore the file in another path? Otherwise, it would cause a breaking change.
• Could you update versions in *.csproj and AssemblyInfo.cs if you are going to release?

Additionally, if you can update the pr name to a more descriptive one other than SDK change in 09.21 would be better.

Thanks

Hi @YalinLi0312 , for #1 The files I deleted in src/Extenisons have been restored in src/Models dic, It will not cause break changes.
for #2 The versions has been updated in previous PR, so this PR need not update the versions.

BTW, could you response my question in my email why the models could not generate the attribute of JsonObject when model name is the same with ‘x-ms-discriminator-value’ value. e.g 'WebActivity'.

@YalinLi0312 delete TabularPartitionOption file due swagger has delete this model and sdk has no referrences with this file, so there is no break change.

@Jingshu923, Our definitions of breaking change is different. Breaking change for us means that new version will break customer's code (compile/runtime) and require user to modify the code, recompile and re-deploy. So yes, this is a breaking change for SDK even though it is intentional breaking change originated from REST API model change.
