EFCore.NamingConventions: 6.0.0-preview.3 stopped working with the release of .NET 6.0 RC1 yesterday

It was working through preview 7 just fine.

Here is the StackTrace

System.TypeLoadException: Method 'GetServiceProviderHashCode' in type 'ExtensionInfo' from assembly 'EFCore.NamingConventions, Version=6.0.0.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7' does not have an implementation.
   at EFCore.NamingConventions.Internal.NamingConventionsOptionsExtension.get_Info()
   at Microsoft.EntityFrameworkCore.DbContextOptions.GetHashCode()
   at System.Collections.Concurrent.ConcurrentDictionary`2.GetOrAdd[TArg](TKey key, Func`3 valueFactory, TArg factoryArgument)
   at Microsoft.EntityFrameworkCore.Internal.ServiceProviderCache.GetOrAdd(IDbContextOptions options, Boolean providerRequired)
   at Microsoft.EntityFrameworkCore.DbContext..ctor(DbContextOptions options)

Also reverting back to 5.x yields the same exception.

Yeah, this is expected - I will be porting the extension to rc1 in the coming weeks…

@roji I get no credit for the PR that goes to our main man @ZvonimirMatic

@roji I created the pull request: https://github.com/efcore/EFCore.NamingConventions/pull/93

A couple of other changes needed to be made. I also updated the version of extension packages, I hope that’s all right. All the changes are listed in the PR.

Oops, sorry… Thanks @ZvonimirMatic !

Thanks @roji everything ran perfectly!

Release 6.0.0-rc.1, thanks @buvinghausen!

@buvinghausen note cd128bbd1342ec13e58137198463e5600ed43abb with some minor fixup to this PR.

EF Core changed the contract for the extensions: https://github.com/dotnet/efcore/issues/26022

Maybe it would be a good idea to upgrade to RC1 version of EF Core?
