This article is a practical description of the problem, which uses the Entity Framework, based on WinForm data binding technology, and the SQL Server database to manage LeetCode problems that we have done. LeetCode manager will manage problems according to "LeetCode tags", such as Array, HashTable, Stack, Tree, Graph etc... Under each category problem can be created, deleted, modified, and one problem may be associated with multiple tags, so this is a typical instance used to solve many-to-many relationship.
