  System.TypeInitializationException: 'The type initializer for 'Microsoft.Practices.EnterpriseLib...

  Apr 19, 2020 06:14 PM|SSK_Nani|LINK

  Hi Team,

  I am using this namespace using Microsoft.Practices.EnterpriseLibrary.Data; to connect the database.

  public static Database CreateDatabase(string connectionString,bool isEncrypted=false)
  {
  try
  {
  string decryptedConnectionString;
  if (isEncrypted)
  {
  decryptedConnectionString = DecryptConnectionString(connectionString);
  }
  else
  {
  decryptedConnectionString = connectionString;
  }
  Database database = new SqlDatabase(decryptedConnectionString);
  return database;
  }
  catch(Exception ex)
  {
  throw new Exception("Error reading database details. Error:" + ex.Message);
  }
  }

  At this line Database database = new SqlDatabase(decryptedConnectionString);, I am getting below exception.

  I am using Asp.Net core 3.0 Web API

  System.TypeInitializationException: 'The type initializer for 'Microsoft.Practices.EnterpriseLibrary.Data.Database' threw an exception.'

  FileNotFoundException: Could not load file or assembly 'System.Management, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

  I'm pretty sure you need to drop to ASP.NET Core 2.1 to use Enterprise Library 6.  ASP.NET 3.0 is not compatible with .NET Framework and it appears Enterprise library is no longer supported.

  Hi SSK_Nani ,

  From the link mgebhard provided, it seems that ASP.NET Core 3.0 does not support Enterprise library .

  For your issue, it is more related with Enterprise Library which is a third party product, I would suggest you submit your issue for more help below:
