@Rezakazemi890 The code no longer aligns with the text that surrounds it.

Note for team: I'm not sure what value there is in showing multiple parameters.

@ajcvickers Do you mean this part of the text? https://learn.microsoft.com/en-us/ef/core/querying/sql-queries#passing-parameters:~:text=In%20the%20above,rejecting%20such%20inputs.

And that it should be changed according to the code? If you approve, I will change that part of the text as well.

@ajcvickers I agree - I don't see what value this adds... Better keep the samples simple and minimal.
