The code generated for LINQ to SQL is a set of partial classes - one for your DataContext and one per entity mapped to a table or a view. That means you have the opportunity to augment the generated code with additional code in your p...

that I know about LINQ is that if the Developers don't know what they're doing, virtually every parameter passed to the database is NVARCHAR(), which makes a whole lot of the code non-SARGable due to "implicit casts". More specifically, I believe it was a product called LINQ2SQL, ...

To this SQL: selectcount(*)fromProductswhereCategoryId = 1 With the approach that the EF uses, they will have to load the entire collection. But all of those are just optimizations, not the make-or-break for the feature. Here is a common scenario that is going to break it: ...
Dapper is nothing more than a utility wrapper over ado.net; it does not change how ado.net ...
I now spent at least two days to figure how I could benefit from “LINQ to SQL” in my projects. This was funny but quite useless: I just went back to use the good old “ODBC connection strings” and manipulating the data as I do already since 10 years. ...
String: foreach (char item in myString) will directly use myString.Length instead of call myString.GetEnumerator(). Array: foreach (var item in myArray) will directly use myArray.Length instead of call myArray.GetEnumerator(). LINQ-enabled objects: foreach will execute the LINQ query ...
Next there is the fact that LINQ to SQL provides very limited mapping capabilities. For the most part L2S classes must be one-to-one with the database (with the exception of one form of inheritance where there is a single table for all of the entity types in a hierarchy and a discrimi...
ado.net just passed a string from your program down to the provider without manipulating that string at all, and if you wanted to move an app from Oracle to SQL Server, you would have to change a number of the queries. With the EF, the queries are written in LINQ or Entity SQL and...
