I need help with dynamic content in my project.
I want to add objects into content while game is running, but i don't know how. Everything i've found need restart app, but i don't want :/
Know somebody how to solve this problem ?
There isn't an easy answer when it comes to XNA - as the content pipeline is more or less intended to be an "offline" process. Also, its much harder to distribute programs that use the content pipeline at runtime since the end-user needs the XNA game studio to be installed.
With that said, for PC XNA applications, there isn't anything stopping you from loading models at runtime. Its just a matter of processing the content yourself, without the content pipeline. E.g. loading a model and storing the geometric data into your own data structures (vertexbuffers/index buffers) that get rendered.
I believe in XNA 4.0 the only (major) roadblock will be for an effect, as there is no way to compile an effect at runtime without the content pipeline.
