Does using assembly compiled in older version of .NET framework affects whole performance?
问题 Lets imagine that we have two assemblies: Foo.Logic (compiled on .NET 2.0 framework) Foo.Application (compiled on .NET 4.0 framework) that have reference and uses compiled Foo.Logic. Does it have impact on Foo.Application performance (or have any other drawbacks)? 回答1: In the situation you described in the question, everything will Just Work™ without any problems. A .NET 4.0 application will load a .NET 2.0 library directly into the .NET 4.0 runtime environment. It will not use side-by-side
