AddVersionedApiExplorer Extension missing

i tried to configure aspnet api versioning as follow ASP.NET Core Versioned API Explorer

so i added following nuget packages

<PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning" Version="2.3.0" />
<PackageReference Include="Microsoft.AspNetCore.Mvc.Versioning.ApiExplorer" Version="2.2.0" />

but compiler complain

Severity Code Description Project File Line Suppression State Error CS1929 ‘IServiceCollection’ does not contain a definition for ‘AddVersionedApiExplorer’ and the best extension method overload ‘IServiceCollectionExtensions.AddVersionedApiExplorer(IMvcCoreBuilder, Action<ApiExplorerOptions>)’ requires a receiver of type ‘IMvcCoreBuilder’

on this line

services.AddVersionedApiExplorer( o => o.GroupNameFormat = “'v’VVV” );

have you removed AddVersionedApiExplorer method ? or any issue on my configuration ?

Thanks

In version 2.x.x, the setup is services.AddMvcCore().AddVersionedApiExplorer(), but in version 3.x.x+ it has the simplified form of services.AddVersionedApiExplorer(). Sorry about the confusion. I haven’t had enough time to fully update the wiki to call out these differences.

I don’t think so, but what are you trying to achieve? services.AddMvc() always implicitly calls services.AddMvcCore() on your behalf. The point of having it hang off of AddMvcCore is to support scenarios where the entire MVC stack is not being used (e.g. no UI/APIs only). Starting in v3.0 (currently beta), the setup will simply be services.AddVersionedApiExplorer() and the required underlying services will be setup for you.
