Developing admin plugin

Hi!

We have developed an admin plugin, which I have packaged as a nuget package. I am trying to make it work in another project, but it can't find the aspx-file. Where should I put the file? I have tried to put it in the root, in the modules/protected folder etc. But I get 404.

Could someone please post an example of how the nuspec should be configured and how the Url should be set in the GuiPlugin attribute, thanks.

nuspec:

<file src="Views\<folder>\Index.aspx" target="content\modules\_protected\<folder>\" />

Controller:

[GuiPlugIn(Url = ""
