Hi,

DLL hell is not the problem of dot net. Dot net provided solution for it.
DLL Hell: In windows applications some dlls are shared ones. Suppose app1 is an application running perfectly. It is sharing a shared dll named shared1.dll. You are installing another application app2. Suppose app2 application is also having a shared dll named shared1.dll. At the time of app2 installation, installer will overwrite the shared1.dll which is already there on our system and being shared by app1. The new shared1.dll may be different than the previous dll which is overwritten. Now the application app1 which is depending on overwritten shared1.dll will become defunct. app1 will fail.
that's all about dll hell.

Dot net shared assemblies are strongly named. Different assemblies with same name but with different version numbers may coexist in shared folders.
This is the solution provided by dot net.
