/optioninfer
Enables the use of local type inference in variable declarations.
/optioninfer[+ | -]
Arguments
- + | -
Optional. Specify /optioninfer+ to enable local type inference, or /optioninfer- to block it. The /optioninfer option, with no value specified, is the same as /optioninfer+. The default value when the /optioninfer switch is not present is also /optioninfer+. The default value is set in the Vbc.rsp response file.
Note
You can use the /noconfig option to retain the compiler's internal defaults instead of those specified in vbc.rsp. The compiler default for this option is /optioninfer-.
