Strawberry shake - Exec(1,1) - All operation must be named

 If you have a query with name then you will get this error during dotnet build. For example, 

query {    <--- missing name 

   book {

    title

   }

}

When you change it  this below, then you will not get a compilation error. Noticed we have appended query with GetBook.

query GetBook {

   book {

    title

   }

}
