With turning third page of google, I didn't find any answer.
But I found the answer by my own.
The issue was comming from the Android.csproj and the Keystore Path.
It was set to my Mac Path even if I had already changed it on
VSWindows AndroidProject => Properties => Signin
So I removed this lines on Android.csproj (edited with third text editor):
<AndroidKeyStore>True</AndroidKeyStore>
<AndroidSigningKeyStore>YourMacPath/Alias.keystore</AndroidSigningKeyStore>
<AndroidSigningStorePass>Password</AndroidSigningStorePass>
<AndroidSigningKeyAlias>Alias</AndroidSigningKeyAlias>
<AndroidSigningKeyPass>AliasPassword</AndroidSigningKeyPass>
On debug & release Part.
Then you can edit them on VS Windows.
Hope I helped someone.
See ya
