LINQ: implement IN tables with LINQ to Entity

In SQL so many times we need to filter value from one table when the values are exist on other table.
As Below

SELECT
   GroupID,
   GroupName,
   GroupNumber, FROM
   TableA WHERE
   GroupID IN (SELECT GroupID FROM TableB) 

You can do it as below:

 var temp =context.TableA
         .Where(x=>context.TableB.Any(y=>y.GroupID!=x.GroupID))
         .Select(x=>new { GroupID = x.GroupID, GroupName=x.GroupName, GroupNumber = x.GroupNumber}).ToList();

or

return DomainContext.TableA.Where(a => DomainContext.TableB.Any(b => b.GroupId == a.GroupId))

I ended up with the code below, which seems to work, but looks very messy, because I think it is parsing the string twice. public static List<int> AuthorisedGroups { get       {             string[] authorisedGroupsStr = ConfigurationManager.AppSettings["AuthorisedGroups"].Split(new char[] { ...
