The breakpoint will not currently be hit. Error

Question

Hello All I am working with windows application C#  i have a solution with 3 projects  projects 1 and 2 are referenced in the 3rd. i had to make a small change(consider bool a = true to false) in 1st project. after this i placed a break point in 1st solution where i made the changes. but at break point i get a strange message like  The breakpoint will not currently be hit. The source code is different then the original version. and after that when i build every thing builds properly newer dlls are created and when i run the project 3 the below things happen 1. does not go to the break point. 2. The changes made in the code does not get reflect in new build Any ideas.. Thanks Vishwas

Hi All I found the solution by hanging around for few hours around it The issue was in Release folder i had old dll and in Debug folder i had new dll. Each time  i was deleting the dlls in Debug as i was building the project all time in debug mode.Once i deleted the old dll in Release folder it worked like a charm.. Still not sure why it was refering to Release dll when i build my project in Debug mode even paths were right.. Thanks Vish

i think in such situation you should clean you solution then rebuild . It should work
