Pragma ImplicitWith directive in AL

  • Article

APPLIES TO: Business Central 2020 release wave 2 and later

The #pragma implicitwith instruction changes the compiler behavior to not create an implicit with. This can be used as a temporary solution to avoid getting warnings on the usage of implicit with statements in the code, that you plan on rewriting but just haven't fixed yet. With the #pragma implicitwith disable, you disable the emit of implicit with warnings for a specific location in code that follows the instruction, and with #pragma implicitwith restore you restore the warning back to its original state. If you don't restore, the disable instruction is valid for the rest of the file.

In the app.json file, you can set the NoImplicitWith flag to disable implicit with when you've rewritten all code. For more information, see JSON Files.

Note

With Business Central 2022 release wave 2, the AL:Go! template for creating new AL projects in Visual Studio Code, now enables explicit with statements by default, by adding the NoImplicitWith option to the features property in the generated app.json file.

Important

It's important to be aware that the implicitwith warning will become an error in a future release and therefore suppressing it should be a temporary solution. It's recommended to rewrite code as described in Deprecating Explicit and Implicit With Statements.

Syntax

#pragma implicitwith disable

#pragma implicitwith restore
