Breakpoints not working

I have the same problem. I watched the video but it didn't address the problem. Fro some reason something changes in the the VS-Unity connection and instead of a red dot for the breakpoint I get a hollow red/yellow dot. When I highlight it I get the following message:

The breakpoint will not be currently hit. Unable to find corresponding location.

I tried selecting Attach Unity Debugger in the debug dropdown in VS but this didn't work. I have reinstalled Unity and that didn't clear up the problem either. I am using VS 2107.

I've seen other posts describing this problem but no solutions!

It happens to me probably after a non-Monobehavior or an abstract class and/or its file name is renamed within VS, or after some files are renamed from Unity. Usually generic abstract classes cause the problem. I suppose somehow the code sync with Unity breaks.

• Close VS.

• Delete Assembly-CSharp.csproj and Assembly-CSharp-Editor.csprojin your project folder.

• Open VS.

Edit:

I believe there are more than one issue that causes the same problem.

In some cases where base class is generic, sometimes I can activate break points if I rename generic base classe and file name to ClassName_1 and ClassName_1.cs, where the number is the number of generic types by convention (ex: public abstract class ClassName_1<T> : MonoBehavior)

I am also having the same issue. :( VS 7.5.1, Unity 2018.1.0f2. Re-importing all assets seemed to clear up the issue.

You can try this tutorial: For the MonoDevelop
Or: For the VisualStudio

I had a similar problem, but a different outcome. (In case others are stumbling across this problem today.)

Consider C# classes that use inheritance (with a base class and a child class). If I put a breakpoint in the base class, but the object in the game contains the child class, the execution won't stop at that breakpoint. It runs the code and prints any Debug.Log(...), but doesn't stop at the breakpoint.
