Getting error "...have the same exposed names. Use correlation names to distinguish them."

I have table [Product].Items and table [Technology].Items
Note that Product and Technology are schema names, so more accurately, I have table Items in schema Products and table Items in schema Technology.

When I try to execute
SELECT [Product].Items.* FROM [Product].Items LEFT OUTER JOIN [Technology].Items ON [Product].Items.ItemID = [Technology].Items.ID

I get the error
Msg 1013, Level 16, State 1, Line 1
The objects "technology.items" and "product.items" in the FROM clause have the same exposed names. Use correlation names to distinguish them.

Why is this error occuring and what do I need to do to fix it?

Not sure about this , can you replace * with the desired column names in the Query

SELECT ProItms.Column1,  ProItms.Column2,ProItms.Column3
FROM [Product].Items ProItms
LEFT OUTER JOIN [Technology].Items
ON ProItms.ItemID = [Technology].Items.ID

SELECT ProItms.*
FROM [Product].Items ProItms
LEFT OUTER JOIN [Technology].Items  TechItms
ON ProItms.ItemID = TechItms.ID

That works, but it requires rewriting all multi-part identifyers (i.e. the TechItms.ID cannot be written as [Tech].Items.ID), which will require me to go through and rewrite a bunch of code.

Is there any other way of fixing this?
