Expression with value converter could not be translated

[Schaemelhout]

I have created a value converter to store a list of strings as a semicolon-separated string and it looks like EF Core can't translate a LINQ expression to filter these and evaluates it locally.

Is this an example of what's stated in the limitations section of the docs? Or is there another way for me to have EF translate this WHERE statement correctly (apart from writing raw SQL)?

Use of value conversions may impact the ability of EF Core to translate expressions to SQL. A warning will be logged for such cases. Removal of these limitations is being considered for a future release.

Steps to reproduce

public class Post
{
  public int Id { get; set; }
  public string Title { get; set; }
  public List<string> Labels { get; set; }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
  modelBuilder
    .Entity<Post>()
    .Property(x => x.Labels)
    .HasConversion(
      x => string.Join(';', x),
      x => x.Split(new[] { ';' }).ToList()
    );
}

When executing this query:
_dbContext.Set<Post>().Where(x => x.Labels.Contains(".NET CORE")).ToList()
I get the following warning:

Microsoft.EntityFrameworkCore.Query:Warning: The LINQ expression 'where {[x].Labels => Contains(".NET CORE")}' could not be translated and will be evaluated locally.
Microsoft.EntityFrameworkCore.Query:Warning: The LINQ expression 'Contains(".NET CORE")' could not be translated and will be evaluated locally.
Microsoft.EntityFrameworkCore.Database.Command:Information: Executed DbCommand (41ms) [Parameters=[], CommandType='Text', CommandTimeout='30']
SELECT [x].[Id], [x].[Title], [x].[Labels]
FROM [Post] AS [x]
