Description

https://github.com/DapperLib/Dapper.Contrib/blob/cf24f6bdc577b1e071c3764ddfb2cf3382531405/src/Dapper.Contrib/SqlMapperExtensions.Async.cs#L33

The query building for Get/GetAsync do simple string formatting to include the property name for the primary key of the table instead of formatting the escaped column name.

For example, a property named Key with the ExplicitKeyAttribute should work but fails because KEY is a reserved SQL keyword. The column name should be included as WHERE [Key] = @id instead.

Research direction

Start in src/Dapper.Contrib/SqlMapperExtensions.Async.cs at the query-building code around line 33, and compare how Get and GetAsync format the primary-key property name. Done means an ExplicitKey property named Key works on SQL Server because the escaped column name is used in the WHERE clause.
