Error installing CardView NuGet
I'm on Visual Studio 2013 Pro with Xamarin 184.108.40.206, Xamarin.Android 220.127.116.11, and NuGet Package Manager 2.8.5096 on Windows 7 Pro x64.
I did the following to recreate this issue:
1. Created a new Blank Android app.
2. Set the Minimum and Target Android version to API Level 21 (Android v5.0 support).
3. Set to compile using latest platform (API Level 21).
4. Ran the Android SDK manager and ensured that all updates are installed.
5. Right-click References > Manage NuGet Packages > Search for CardView > Install.
6. After I click the CardView Install, I get the "Could not install package" error (see attached screen shot for details).
After some digging and experimentation, I found that adding this to the .csproj file
cleared up the problem and allowed the install to work:
It looks like this element is added to the .csproj when you create the project in Xamarin Studio, but it's NOT added when the project is first created in Visual Studio. If I take an Android 5.0 project that is created in Xamarin Studio, open it in Visual Studio, then try to add the CardView NuGet, then the install works.
We have tried to reproduce this issue and able to reproduce. After we click the CardView Install, CardView NuGet fails to install.
