Run framework 4.0 application without installing on client machine

is there a way to run a windows application in the client machine without installing the .NET framework 4.0? I try to set the "Copy local" to true on all dll's but 开发者_Go百科it doesn't work.

Thanks!

.NET 4.0 is actually a new version of the CLR, so there isn't binary compatibility between assemblies compiles with 4.0 vs. 3.5 and 2.0.

In the case of 3.5, you could just copy local because it was the same CLR as 2.0...but alas, not with 4.0.
