The argument 'name' cannot be null

[programmiererei]

Error with my first page in Radzen-Blazor-Studio: I have no idee where to look for error. Parallel I generated the page with Radzen (Blazor Server): There is no problem.

MSSQL-Database, Table with 3 columns, Page with DataGrid with Inline-Edit:

[Table("tblLagerstellen", Schema = "dbo")]
public partial class TblLagerstellen
{
    [Key]
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int LS_ID { get; set; }

    [Required]
    public string Lagerstelle { get; set; }

    public bool AutomatischerImport { get; set; }

    public ICollection<TblDepot> TblDepots { get; set; }

    public ICollection<TblEbenen> TblEbenens { get; set; }

    public ICollection<TblImportDateien> TblImportDateiens { get; set; }

    public ICollection<TbllandesbankLagerstelleRegexp> TbllandesbankLagerstelleRegexps { get; set; }

    public ICollection<TblmarktLagerstelleRegexp> TblmarktLagerstelleRegexps { get; set; }

    public ICollection<TblproduktLagerstelleRegexp> TblproduktLagerstelleRegexps { get; set; }

    public ICollection<TblRechnungen> TblRechnungens { get; set; }

}

Produces following error:

Hi @programmiererei,

This is probably related to the database schema. You can send an SQL script with it to info@radzen.com
