SQL - transformar consultas SQL a consultas LinQ to SQL

Hola,
estoy comenzando a trabajar con Linq to Sql y no sé hacer ni siquiera consultas simples, descargué de http://www.sqltolinq.com/ el linqer (hace transformaciones de Sql a Linq to Sql) pero da un error durante la instalación,

quería saber si alguien podía transformarme algunas de las consultas SQL que muestro a continuación, no tienen que ser todas, si muestro tantas es sólo porque quería tener un ejemplo de cada comando,

supongamos que tengo las tablas Store_Information ((string)store_name, (decimal)Sales, (datetime)Date) y Geography ((string)store_region, (string)store_name) y la clase ReportesDataContext, estas son las consultas SQL:

1 - select
SELECT store_name
FROM Store_Information

2 - distint
SELECT DISTINCT store_name
FROM Store_Information

3 - where
SELECT store_name
FROM Store_Information
WHERE Sales > 1000

4 - and / or
SELECT store_name
FROM Store_Information
WHERE Sales > 1000
OR (Sales < 500 AND Sales > 275)

5 - in
SELECT *
FROM Store_Information
WHERE store_name
IN ('Los Angeles', 'San Diego')

6 - between
SELECT *
FROM Store_Information
WHERE Date
BETWEEN '06-Jan-1999' AND '10-Jan-1999'

7 - like
SELECT *
FROM Store_Information
WHERE store_name
LIKE '%AN%'

8 - order by
SELECT store_name, Sales, Date
FROM Store_Information
ORDER BY Sales DESC

9 - funciones
SELECT SUM(Sales) FROM Store_Information
SELECT MIN(Sales) FROM Store_Information
SELECT MAX(Sales) FROM Store_Information
SELECT COUNT(Sales) FROM Store_Information
SELECT AVG(Sales) FROM Store_Information

10 - group by
SELECT store_name, SUM(Sales)
FROM Store_Information
GROUP BY store_name

11 - count
SELECT COUNT(store_name)
FROM Store_Information

12 - having
SELECT store_name, SUM(sales)
FROM Store_Information
GROUP BY store_name
HAVING SUM(sales) > 1500

13 - alias
SELECT A1.store_name Store, SUM(A1.Sales) "Total Sales"
FROM Store_Information A1
GROUP BY A1.store_name

14 - join
SELECT A1.region_name REGION, SUM(A2.Sales) SALES
FROM Geography A1, Store_Information A2
WHERE A1.store_name = A2.store_name
GROUP BY A1.region_name

15 - outer join
SELECT A1.store_name, SUM(A2.Sales) SALES
FROM Geography A1, Store_Information A2
WHERE A1.store_name = A2.store_name (+)
GROUP BY A1.store_name

16 - concatenar
SELECT region_name + ' ' + store_name FROM Geography
WHERE store_name = 'Boston';

17 - trim
SELECT TRIM(' Sample ');
SELECT LTRIM(' Sample ');
SELECT RTRIM(' Sample ');

Muchas Gracias de antemano.
