Environment variables:
|
|
|
|
DOTNET_USE_POLLING_FILE_WATCHER
|
|
When set to '1' or 'true', dotnet-watch will poll the file system for
|
|
changes. This is required for some file systems, such as network shares,
|
|
Docker mounted volumes, and other virtual file systems.
|
|
|
|
Remarks:
|
|
The special option '--' is used to delimit the end of the options and
|
|
the beginning of arguments that will be passed to the child dotnet process.
|
|
Its use is optional. When the special option '--' is not used,
|
|
dotnet-watch will use the first unrecognized argument as the beginning
|
|
of all arguments passed into the child dotnet process.
|
|
|
|
For example: dotnet watch -- --verbose run
|
|
|
|
Even though '--verbose' is an option dotnet-watch supports, the use of '--'
|
|
indicates that '--verbose' should be treated instead as an argument for
|
|
dotnet-run.
|
|
|
|
Examples:
|
|
dotnet watch run
|
|
dotnet watch test
