I have visual studio 22 installed, but whenever i open the solution, i get the following error as seem in the image bellow.

At the moment I have succeeded in installing the target park for 4.5.2 but it is not helping.

With help of @JonasH and @Narish, I took time to study the documentation to understand what is happening.

Following an article referenced by @Narish, I made a copy of the v4.5.1 folder in the .NETFramework dir, which is still compatible with v4.5 and renamed it to v4.5

As of this moment, the legacy code and & still opens.
