SqlServer Unhandled Exception

I am using Microsoft Visual Studio Community 2022 (64-bit) - Preview Version 17.8.0 Preview 1.0
I have installed the latest .NET8 SDK Version="8.0.0-rc.1.23421.29"

I implemented PersistenceProvider": "SqlServer and the system built the database ok. I logged in and went to Administrator and created 1 blog and submitted ok. However returning to the dashboard an unhandled exception error was encountered. After each restart the same error.

Just to get things working I tracked down the problem to: LinkDotNet.Blog.Domain BlogPost.cs line 28:

public IReadOnlyCollection Tags { get; private set; }

I changed this to:

public IList Tags { get; private set; }

This created a build error in: LinkDotNet.Blog.Web.Controller RssFeedContoller.cs line 98:

        s => new BlogPostRssInfo(s.Id, s.Title, s.ShortDescription, s.UpdatedDate, s.PreviewImageUrl, s.Tags),

I changed this to [add explicit cast]:

        s => new BlogPostRssInfo(s.Id, s.Title, s.ShortDescription, s.UpdatedDate, s.PreviewImageUrl, (IReadOnlyCollection<string>)s.Tags),

Then all worked.

Hey thanks for reporting the issue.

This is a known regression from preview 7 to rc 1: dotnet/efcore#31722

That said, I will most likely revert the last commit with the update until the issue got fixed.

I reverted the last upgrade on master. That should make everything work again.
