vb.net - I can't assign to a variable named 'CallTypeList' -

-

an unusual issue turned in vb.net project. getting "object or value not set exception" on line of form:

dim calltypelist list(of object) = myorm.recordsettodynamic(sql)

the right hand side of unimportant, in general reads database records via 3rd party api, , copies fields dynamic expandoobjects, individually boxed list(of object) - works, don't worry it.

i've spend 2 hours looking @ of functional structures, when duplicated line, moved earlier in function , called xcalltypelist, renamed 1 worked.

i thought else (active x probably) making execution state uncertain, , continued debugging.

it when exchanged xcalltypelist , calltypelist variable names discovered can't assign variable called 'calltypelist'.

does know what's going on? web searches suggest there isn't peculiar variable name.

i should note i'm using vs2013 community, have installed vs2015 professional, i've yet start using (not sure if makes difference).

thanks.
