MvvmLight 5.4.1.1 source code #90

Open jozefizso opened 4 years ago

We use the MvvmLight v5.4.1.1 package in our project.

We have this call path in the stacktrace and we are unable to match it to the source code:

This stacktrace reports the method Execute() called Invoke() on line 226 in the WeakActionGeneric.cs file. In the master code, line 226 contains if (Method != null only and I cannot find the correct source code in other branches

Which version of the code was the 5.4.1.1 library built with?

WeakActionGeneric.cs file was last updated on Oct 8, 2017 and the 5.4.1.1 library is from Sep 2018 - that's why I'm struggling with find the right source code for it.
