Force Nuget to download all packages again

Hello,
If Nuget isn't restoring the packages correct, we have a problem because we have a depedency to Nuget.
If you have a project where some references from nuget are missing and the option "restore nuget packages" is not available, here is a maybe dirty but working solution.
First make sure that "Allow NuGet to download missing packages" and "Atuomatically check for missing packages during build in Visual Studio" are checked.

After this, make sure that the "package.config" file contains the all the references you need for your project.
To force Nuget to download all the libaries agaiin, delete the "packages" folder in the root path of your solution.
Now rebuild your solution.

Now Nuget should download all the packages again.
