    A simple enough problem on the face of it: Create a Library class C that creates and holds a static BufferBlock<T>instance . Two projects A and B have C as a dependency. All three are in the same Visual Studio solution. Project A and Project B are not aware of each other. When Project A and Project B start up, they request the instance of the BufferBlock from C with a getBufferBlockl() method. The unexpected behaviour is that the same instance is not being returned of the static object from the Library class. Each call from the separate project is being returned with a new instance. Since I want Project B to write into the BufferBlock and for Project A to read from the same BufferBlock this is a problem. Can you solve this problem for me. Update: The solution to this must be...

    We want to build a simple mixed reality tennis game for Oculus Quest 3. It can be built initially, really, as a Unity VR game for Quest 2, but at some point it will be played on a real tennis court using the new Oculus Quest 3 color passthrough feature. The user will simply map the corners of the court and the net and the Oculus will take care of everything else, so its more or less a VR build. The game should have fun deviations on tennis, such as prizes and awards that can be collected on the court and give the player advantages over their opponent We want to spice tennis up and make it more of a video game experience. Ball effects and speeds, player powers, different things. It does not need to be super advanced, just fun and simple. We'd like to get the project done in 6 mont...
