I'm removing dependency to some component from solution. Some C# projects in their directory contain file licenses.licx and have reference to this file in their text csproj representation. Most of licenses.licx reference only component I'm removing from solution. How to clean this referenses:
The easiest thing to do is show all files in the project within visual studio. When you do this, the .licx file will be shown.
Double-clicking on it will open it in a text editor, so you can make any changes that you need to.
You can also just delete it from the visual studio solution explorer if you need to (clearing all of the entries in the previous step would have the same effect).
