I am seeing this error attempting to use static abstracts in a .net 6 project
JJayy8/14/2022

ahh ok, have fun
JJayy8/14/2022
ohh wow ok, so i upgraded my sdk from 6.0.1 -> 6.0.4 and it started failing for me
JJayy8/14/2022
fascinating
JJayy8/14/2022
this feels like a bug
OOrannis8/14/2022
Show code, but likely not a bug

See https://github.com/dotnet/csharplang/issues/5955

did this ship 5 days ago as part of 6.0.8 of the runtime?
OOrannis8/14/2022
Wouldn't surprise me
JJayy8/14/2022

and code is this 
public interface IQueryResult<T> : IResult<T, QueryStatus>
{
    static abstract IQueryResult<T> Success(T? val);
    static abstract IQueryResult<T> Invalid(T? val);
    static abstract IQueryResult<T> NotFound();
    static abstract IQueryResult<T> Conflict();
    static abstract IQueryResult<T> Forbidden();
}

for a moment i thought you had lied to us all about your name
JJayy8/14/2022
    public class Handler(ClemBotContext _context) : IRequestHandler<Command, IQueryResult<Model>>
    {
    }
