Tezava pri instanciranju class-a

Spostovani!

Imam sledec problem: V Visual Studio 2010 Ultimate imam v solutuin-u dva projekta, prvi projekt je dll, drugi projekt je pa aplikacija, ki uporablja ta dll za komunikacijo z neko napravo (kot je razvidno iz prejsnih dveh postov). Sedaj, zbuildam oba projekta in vse lepo in prav. Ko pa pozenem drugi projekt (aplikacijo), mi v vrstici:

bool bConnectionOk = this.m_CoreFunctions.OpenConnection("COM3",
                38400,
                8,
                0,
                0);

javi runtime error (v zgornji vrstici probam uporabiti metode, ki sem jih dobil pri instaciranju classa iz dll knjiznice, ki sem jo spisal):

System.IO.FileLoadException was unhandled
Message=Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information.

Za to napako sem pogooglal po netu in nasel resitev, da moras v projektni App.config dodati nek text in to sem tudi storil, vendar nic ne pomaga. Mi lahko kdo pomaga s to napako?

Vnaprej se vam zahvljaujem in s spostovanjem,

Jao, tega sem se bal ... Sedaj gledam in sem prisel do sledecega sklepa: Namrec, moja dll knjiznica uporablja drugo dll knjiznico, ki smo jo kupili in izgleda, da mi ta vrze exception, ker je zbuildana na .NET 2.0. Bom kontaktiral proizvajalca, pa naj mi poslje update-an dll. Je to prava pot?

To ne drži aplikacija lahko mirne volje uporablje knjižnice ki so narajene z prejšno verzijo frameworka.

Drugače pa google veliko o ve o .net frameworku naprimer en copy/paste v google vrne http://goo.gl/45Gcl nevem pa če dejansko reši težavo, to se pa sam mal posveti.

To sem naredil, pa mi ni delalo, zato sem kontaktiral proizvajalca!
