Could not load type 'Umbraco.Cms.Core.Deploy.IGridCellValueConnector2'

Trying to upgrade one of our Cloud sites to v11 and getting the following error locally preventing the application from booting. Looks like something is missing...

TypeLoadException: Could not load type 'Umbraco.Cms.Core.Deploy.IGridCellValueConnector2' from assembly 'Umbraco.Infrastructure, Version=11.0.0.0, Culture=neutral, PublicKeyToken=null'.

The package references we have in our csproj are as follows:

<PackageReference Include="Microsoft.ICU.ICU4C.Runtime" Version="68.2.0.9" />
<PackageReference Include="Umbraco.Cloud.Identity.Cms" Version="11.0.18" />
<PackageReference Include="Umbraco.Cloud.StorageProviders.AzureBlob" Version="11.0.0" />
<PackageReference Include="Umbraco.Cms" Version="11.0.0" />

Hi Callum! We did change related interfaces in 11.0.0-rc2 (PR umbraco/Umbraco-CMS#13287), but since that introduced breaking changes, reverted those and added new versions, including IGridCellValueConnector2 in 11.0.0-rc6 (PR umbraco/Umbraco-CMS#13489). Your project seems to be using an outdated assembly that doesn't contain this interface, hence the error...

You can verify that the Umbraco.Infrastructure version 11.0.0.0 assembly does contain the Umbraco.Cms.Core.Deploy.IGridCellValueConnector2 type on FuGet.

Maybe your local NuGet cache contains the wrong version (use dotnet nuget locals all --clear to clear this) or a package is preventing the transitive dependency on Umbraco.Cms.Infrastructure to update to the final 11.0.0 version?

Thanks @ronaldbarendse, you were absolutely right here!
