.net entity-framework sql sql-server timestamp

Select new records by timestamp column with Entity Framework

I have a table with timestamp column (RowId) in my SQL Server database.

I want to query new rows according to this timestamp. The SQL query is following

FROM [MyTable]
where RowId>=0x0000000000A99B06

0x0000000000A99B06 is a max timestamp value from the previous query.

How can I make such a query using Entity Framework database-first? RowId maps to byte[] property and I have no idea how to compare byte arrays in a LINQ query.
