issue with PostSharp cannot find assembly for system.web.mvc, version=3.0.0.0 when no projects reference it

Question

I\'m using PostSharp, and this was working fine. Recently, we upgraded some projects to the MVC version 5.2. Today, I loaded up an old project which was using version 4.0

Add the code below inside your [project].csproj file. To achieve this follow the steps:

• Right-click in your Project;
• Unload Project;
• Then right-click in unloaded project and click Edit [project].csproj;
• Look for a tag of PostSharp;
• Then add the following code right below the tag;
• Then Reload the project;

Code:

    web.config

Your xml code should look something like:

    web.config
