I've been trying to develop for Xamarin Forms ( using UWP and utilizing Sqlite-net-pcl in the process. I tried adding a UWP project to my existing XF app and noticed a ton of errors when calling Sqlite-net-pcl classes and methods from a PCL class, so I decided to see if I could reproduce this with an entirely new solution. To my delight, I was able to. I checked around and made sure that my projects had the same NuGet package versions and also made sure I had the SQLite Universal package and the VS 2015 C++ references added to my UWP package.

The error seems to be a false positive, but it does make debugging weird. 

This happens only when Xamarin Forms is involved. I tested with a simple PCL library sans XF that I call directly from my UWP's MainPage.xaml and I get no FileNotFoundExceptions. I even attempted to add the class that held my Sqlite-net calls in the rendererAssemblies list that gets called on Forms.Init, and that did nothing for me.

My issue should be easy to reproduce. Create a solution, add XF, and a PCL. Add Sqlite-net-pcl to all projects. Create a class within the PCL and simply try to add a SQLite db and insert random test data to it.

I can add more information if needed.

Hi this is not a Xamarin.Forms particular issue. Please take a look at other SQLite samples on UWP and Xamarin

Make sure you are using the correct SQLite versions.

I am definitely using the correct SQLite versions. As I said, it only happens when I am particularly using Xamarin Forms and calling from a PCL. In another project that I created that was purely UWP using the SAME packages, I don't get this issue. As soon as I call sqlite-net-pcl from a PCL from within Xamarin.Forms, I get errors. I cannot reproduce this issue when it's not being called from Xamarin Forms. Heck, if I move the code directly to the Device Project's Main.xaml.cs and run it, I don't even get the issue.

You need to check with sqlite-net-lcl github project since it's a a package related issue.
Comment 4 Jeremy Sinclair 2016-08-10 17:18:12 UTC
I don't know if it's purely a PCL issue though. I only get this when I'm calling it from the Xamarin Forms PCL project. If I call it from any other PCL, then I have no issue.
