How to get rid of the error 'System.Collections.Generic.IEnumerable' does not contain a definition for 'ToList'

Suppose we have the below entities

class PersonName
{
	public int Id { get; set; }
	public string Name { get; set; }
}

class PersonAddress
{
	public int Id { get; set; }
	public string Address { get; set; }
}

class PersonInfo
{
	public int Id { get; set; }
	public string Name { get; set; }
	public string Address { get; set; }
}

Now we want to combine the result of the PersonName and PersonAddress collection and the combined result want to store in List PersonInfo.

Intially the program was

List<PersonName> lstPersonName = new List<PersonName>();
Enumerable.Range(1, 10).ToList().ForEach(i => lstPersonName.Add(new PersonName { Id = i, Name = "Name" + i.ToString() }));

List<PersonAddress> lstPersonAddress = new List<PersonAddress>();
Enumerable.Range(1, 10).ToList().ForEach(i => lstPersonAddress.Add(new PersonAddress { Id = i, Address = "Address" + i.ToString() }));

List<PersonInfo> lstPersonInfo = 
							(
								from a in lstPersonName
								join b in lstPersonAddress on a.Id equals b.Id
								select new 
								{
								   Prop1 = a.Id
								   ,
								   Prop2 = a.Name
								   ,
								   Prop3 = b.Address
								}
							 ).ToList();

Upon compiling, we encounter the below error

'System.Collections.Generic.IEnumerable<AnonymousType#1>' does not contain a definition for 'ToList' and the best extension method overload 'System.Linq.Enumerable.ToList<TSource>(System.Collections.Generic.IEnumerable<TSource>)' has some invalid arguments

Then we changed the .ToList() to .ToList<PersonInfo>() as under

List<PersonInfo> lstPersonInfo =
								(
									from a in lstPersonName
									join b in lstPersonAddress on a.Id equals b.Id
									select new
									{
										Prop1 = a.Id
									   ,
										Prop2 = a.Name
									   ,
										Prop3 = b.Address
									}
								 ).ToListList<PersonInfo>();

but with the same error.

Now why it is happening?

Because, we tried to create a sequence of a new anonymous type and tried to call ToList<PersonInfo> on it which will never work. We should create a PersonInfo
directly by writing new PersonInfo { ... } as under

List<PersonInfo> lstPersonInfo =
								(
									from a in lstPersonName
									join b in lstPersonAddress on a.Id equals b.Id
									select new PersonInfo
									{
										Id = a.Id
									   ,
										Name = a.Name
									   ,
										Address = b.Address
									}
								 ).ToList();

Hope this is useful.
