VS 2015 Isolated Shell: Supporting Menu Command Localizing

Hi,

I am exploring the example code for WPFToolWindow. I want test menu localizing for "Persisted Window" string text.

What I was hoping to do is something like this...

<Buttons><!-- An element inside this section is defined by its ID and must specify a parent group, a display
           priority, an image, a type, some visibility flags (optional) and a default text. --><Button guid="guidClientCmdSet" id="cmdidPersistedWindow" priority="0x100" type="Button"><Parent guid="guidSHLMainMenu" id="IDG_VS_WNDO_OTRWNDWS1" /><Icon guid="guidImagesBmp" id="bmpPicX" /><Strings language="en-us"><ButtonText>&amp;Persisted Window</ButtonText><Strings language="en-us"><ButtonText>&amp;Persisted Window</ButtonText></Strings>

<Strings language="en-ES"><ButtonText>&amp;Persisted Window(ESP)</ButtonText></Strings>

</Button>

My modification of VSCT file doesn't work. After browsing the forum I found link to a post suggested to check https://msdn.microsoft.com/en-us/library/ee943168.aspx. I already looked at the https://msdn.microsoft.com/en-us/library/ee943168.aspx the link but it did not work for me on the example code. Also is there a future plan for isolated Shell so this Menu localizing will be lot simpler then what it is now?

What I am particularly looking for to load these menus from the xml or simple text (INI) file.

Thanks 

AG
