 If you encounter a bug when you use the new JIT, and if the bug manifests itself in a function in an NGEN native image (see [here](https://msdn.microsoft.com/en-us/library/6t9t5wcf(v=vs.110).aspx) for details), use any of the following methods to force certain named assemblies to be recompiled by the JIT and not use the existing native images. You will generally pair one of these methods with the same numbered method above to get an NGEN image to fall back to JIT compilation, and, in addition, do that JIT compilation with the legacy JIT.
 
-In the examples below, we wish to prevent using the NGEN images of three assemblies, named `assembly_one.dll`, `assembly_two.dll`, and `assembly_three.dll`. We specify the assemblies using simple assembly names (no public key token, no architecture, and so on). The assembly names are specified without using the `.dll` file name extension.
