asp.net - Exception: Argument must be either a FieldInfo or PropertyInfo On server -

-

the environment:

  • development pc: windows 7 x64 clean install, visual studio 2012 , iis 7.5
  • deployment server: windows 2008 w/ sp2, iis 7, .net 4.0 (not sure if it's 32 or 64 bit)
  • language: vb
  • codebase: classic asp, new code additions done in asp.net using

the backstory:

i rewriting section of our intranet admin site. have bunch of code (20+ files) under directories in app_code 2 namespaces defined. have aspx page in subfolder of site uses code in app_code. running linq query pulls down data sqlserver display on page.

the issue:

when code deployed server, linq-to-sql query errors out 

stack trace:     [argumentexception: argument must either fieldinfo or propertyinfo]     system.linq.expressions.expression.validatesettablefieldorpropertymember(memberinfo member, type& membertype) +2751766     system.linq.expressions.expression.bind(memberinfo member, expression expression) +48     {my aspx file class}.{defined function} in {my aspx.vb file}     {my aspx file class}.pageload() in {my aspx.vb file}     {my aspx file class}._lambda$__1(object a0, eventargs a1) in c:\windows\microsoft.net\framework\v4.0.30319\temporary asp.net files\root\06df741c\5a279add\app_web_{my aspx file name}.aspx.2589a445.y_7knnxz.0.vb:0     system.web.ui.control.onload(eventargs e) +91     system.web.ui.control.loadrecursive() +74     system.web.ui.page.processrequestmain(boolean includestagesbeforeasyncpoint, boolean includestagesafterasyncpoint) +2207

the linq query runs fine on local machine's iis server, , in visual studio 2012's dev server; not on public web server.

other linq queries on other .net aspx pages work, , have used many functions way. have tried removing namespaces, adding line continuation characters, etc... trying shotgun hairbrained ideas @ it. have searched as find answer, , can find code files throw error.

i in proccess of trying clone environment in vm (run eval copy of server 2008) , host site in it.

any offered appreciated.

it appears there issue way environment on server handling public variables vs public properties linq queries when doing my

select new myclass { .var1 = result.variable }

i added property modifier variable:

class myclass     public property var1 end class

instead of 

class myclass     public var1 end class
