The timeout period elapsed prior to completion of the operation or the server is not responding. question :APPServerContext does not contain CommandTimeOut. How do I handle this error

You can set the Command Timeout value in the DbContext's configuration options using the "CommandTimeout" property. You can do this either in the OnConfiguring method or when creating a new instance of DbContextOptionsBuilder. Here's an example of setting the Command Timeout value to 60 seconds:

protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
    optionsBuilder.UseSqlServer(connectionString)
        .ConfigureWarnings(warnings => warnings.Throw(RelationalEventId.QueryClientEvaluationWarning))
        .CommandTimeout(60);
}

Alternatively, you can also set the Command Timeout value when executing the SQL query using the "CommandTimeout" property of the DbCommand object. Here's an example:

using APPServerContext context1 = new APPServerContext(LoginInfo.DBAias, LoginInfo.UserID);
await context1.Database.BeginTransactionAsync().ConfigureAwait(false);
var command = context1.Database.GetDbConnection().CreateCommand();
command.CommandText = exeSqlList[i];
command.CommandTimeout = 60;
context1.Database.OpenConnection();
var result = await command.ExecuteNonQueryAsync().ConfigureAwait(false);

This will set the Command Timeout value to 60 seconds for the current SQL query execution.
