win_dotnet_ngen - Runs ngen to recompile DLLs after .NET updates

New in version 2.0.

Synopsis

After .NET framework is installed/updated, Windows will probably want to recompile things to optimise for the host.
This happens via scheduled task, usually at some inopportune time.
This module allows you to run this task on your own schedule, so you incur the CPU hit at some more convenient and controlled time.

Common return values are documented here Return Values, the following are the fields unique to this module:

name	description	returned	type	sample
dotnet_ngen64_eqi_exit_code	The exit code after running the 64-bit ngen.exe executeQueuedItems command.	64-bit ngen executable exists	int	0
dotnet_ngen64_eqi_output	The stdout after running the 64-bit ngen.exe executeQueuedItems command.	64-bit ngen executable exists	str	sample output
dotnet_ngen64_update_exit_code	The exit code after running the 64-bit ngen.exe update /force command.	64-bit ngen executable exists	int	0
dotnet_ngen64_update_output	The stdout after running the 64-bit ngen.exe update /force command.	64-bit ngen executable exists	str	sample output
dotnet_ngen_eqi_exit_code	The exit code after running the 32-bit ngen.exe executeQueuedItems command.	32-bit ngen executable exists	int	0
dotnet_ngen_eqi_output	The stdout after running the 32-bit ngen.exe executeQueuedItems command.	32-bit ngen executable exists	str	sample output
dotnet_ngen_update_exit_code	The exit code after running the 32-bit ngen.exe update /force command.	32-bit ngen executable exists	int	0
dotnet_ngen_update_output	The stdout after running the 32-bit ngen.exe update /force command.	32-bit ngen executable exists	str	sample output

Note

there are in fact two scheduled tasks for ngen but they have no triggers so aren’t a problem
there’s no way to test if they’ve been completed (?)
the stdout is quite likely to be several megabytes
