from looking @ innermost inner exception, looks app having difficulty connecting oracle. here connection strings, have manually verified work using sqlplus.

  <add name="myapp"    connectionstring="data source=(description=(address=(protocol=tcp)(host=localhost)(port=1521))(connect_data=(server=dedicated)(sid=orcl)));user id=myid;password=mypassword;"    providername="oracleodp-11-2.0" />  <add name="blenderconnection"     connectionstring="data source=(description=(address=(protocol=tcp)(host=localhost)(port=1521))(connect_data=(server=dedicated)(sid=orcl)));user id=ppdid;password=ppdpassword;"     providername="oracle.manageddataaccess.client"/>  <add name="oracle"      connectionstring="data source=(description=(address=(protocol=tcp)(host=localhost)(port=1521))(connect_data=(server=dedicated)(sid=orcl)));user id=myid;password=mypassword;"      providername="oracle.manageddataaccess.client"/> 

does have suggestions? tia.

the way stopped getting above exception uninstall teamcity , remove application's website iis manager.

to clear, don't think problem teamcity--the problem ran build deploy application, added website iis , caused sort of conflict produce error in question when tried debug website.

also, part of problem was receiving exception:

exception details: system.badimageformatexception: not load file or assembly 'oracle.dataaccess' or 1 of dependencies. attempt made load program incorrect format.  badimageformatexception: not load file or assembly 'oracle.dataaccess' or 1 of dependencies. attempt made load program incorrect format.]  [badimageformatexception: not load file or assembly 'oracle.dataaccess, version=2.112.3.0, culture=neutral, publickeytoken=89b483f429c47342' or 1 of dependencies. attempt made load program incorrect format.]    system.reflection.runtimeassembly._nload(assemblyname filename, string codebase, evidence assemblysecurity, runtimeassembly locationhint, stackcrawlmark& stackmark, intptr pprivhostbinder, boolean throwonfilenotfound, boolean forintrospection, boolean suppresssecuritychecks) +0 

to resolve above problem, installed 32-bit client, mistakenly installed 1 oracle 12, in fact needed oracle 11g 32-bit client:

odac121021xcopy_32bit.zip 

to fix problem, uninstalled above, , made sure explicitly uninstall oracle.dataaccess.dll 2.121 items c:\windows\assembly. installed proper oracle 11g 32-bit client:

 odtwithodac1120320_32bit.zip 

next, updated file , ran it:

c:\app\oracle\product\11.2.0\dbhome_1\bin\selecthome.bat 

then opened file:

c:\oracle\configure.bat 

to make sure had values of 2.121.2.0 changed 2.112.3, , ran file this:

c:\oracle>configure.bat oracle_home true 

once file has executed, of machine.config files found in places c:\windows\microsoft.net\framework\v2.0.50727\config\machine.config should have version number oracle.dataaccess set properly.

but rather messing around above, instead highly recommend working managed .net client has been released if can:

http://www.oracle.com/technetwork/topics/dotnet/index-085163.html

unfortunately, right have work unmanaged client.
