Dapper FastCRUD Getting Started

Dapper.FastCrud is a small NuGet library that extends the IDbConnection for Dapper and is based on C# 6 and VB 14 essential features that have finally raised the simplicity of raw SQL constructs to acceptable maintenance levels.

The following is the list of extension methods that are provided in Dapper.FastCrud.

Method Description
Get Retrieve a record based on the primary key.
Find Retrieve a list of records from a table.
Insert Inserts a row into the database.
Update Update a record in the database.
BulkUpdate Updates a list of records in the database.
Delete Delete a record based on primary key
BulkDelete Deletes all the records in the table or a range of records if a conditional clause was set up in the statement options.
Count Counts all the records in a table or a range of records if a conditional clause was set up in the statement options.

For projects targeting .NET 4.5 or later, you can also use the async versions of all the above methods.
