Joining two repos.GetAll() using where clause.

We are using ABP to upgrade an old system which contains a lot of embedded SQL in code, and we want to translate the SQL text into C# query expression as much as possible.

The old SQL code used where clause to join tables, but ABP seems not support it…

We know we can use join ... on ... equals in ABP, like this:

var records = from user in userRepo.GetAll()
                   join userRole in userRoleRepo.GetAll() on user.Id equals userRole.userId
                    ...

But if we want to translate the SQL like this:

var records = from user in userRepo.GetAll()
                  from userRole in userRoleRepo.GetAll()
                  where user.Id == userRole.UserId
                  ...

It throws LINQ to Entities does not recognize the method 'System.Linq.IQueryable``1[UserRole] GetAll()' method, and this method cannot be translated into a store expression.

So I can only use join ... on .. equals to join tables in ABP?

Let it be open. I added to it backlog to consider to convert GetAll to a property.

If this is a general problem and adding a property helps to overcome these problems, we may consider to add a property to IRepository which returns IQueryable.
