So my friend sent me a folder with .exe and .dlls to update the .net framework.

I can decompile everything with jetbrains

I then tried to recompile it with new .net framework

But for some reason, it won't detect the dependents it to use.

Using visual studio 2015

i'm not sure i understand what you're trying to do. are you trying to update .NET? if so, why aren't you using the microsoft site? or are you trying to get the working source code for his project? if so, you should be able to just "add reference" and select the dll.

I did add reference and select the DLL.

Visual studio, then said can't find reference to a function in the DLL I added as a reference...

is it public? do you have documentation for it? or did he write the code?

self wrote

so create the project from source yourself and add a reference to the existing project instead of dll. see if that fixes it. make sure the method is public

You are probably missing a targeting pack for the new version of the .NET framework. When you add the DLL as a reference is there a yellow triangle next to it? If so, make sure the project is targeting the correct version of .NET, and if you still get compile errors look for a targeting pack patch for Visual Studio 2015 for the version of .NET you are updating.
