Xamarin Forms UWP - Unable To Debug Shared Code

Question

I've recently started having this issue for the latest version of Xamarin Forms with .NET standard 2.0 as the code sharing strategy.

I am able to place a breakpoint and stop in any code that lives in the UWP project but if I place a breakpoint in the shared DLL code, the breakpoint turns from solid red to a red outlined circle filled in with white. When I put my mouse over the breakpoint, it says the symbols have not been loaded for that location.

What am I doing wrong to be able to debug the shared code for Xamarin Forms UWP? Android and iOS work.

Remove bin folder and try again, maybe it’s not rebuilding with correct reference — Krishna, Jan 22 '18 at 03:27

What am I doing wrong to be able to debug the shared code for Xamarin Forms UWP? Android and iOS work.

It's known issue in Visual Studio. Currently, there is a workaround that you could refer.

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' ">
    <DebugType>Full</DebugType>
</PropertyGroup>

Place the above code in the .NET Standard Library csproj file.

I added this to the .NET Standard library and it worked. Thank you so much! – SolidSnake4444 Jan 24 '18 at 15:48
for me this does not work on Xamarin.Android projects (when trying to debug .net standard 2.0 library). Any other ideas? – The Chris Apr 03 '19 at 15:45
Also delete all the files at C:\Users\username.domain\AppData\Roaming\Microsoft\VisualStudio. They are just temp files with potentially major impacts when you really need to clean all files, especially when you are trying to change build parameters. – Marc George Jun 23 '20 at 00:29

Select the UWP project as startup project and then open Build menu and choose Configuration Manager. There make sure that the .NET Standard library is selected in the Build column.

If that does not help, delete the bin and obj folder from both shared library and UWP project and try again. Sometimes also uninstalling the UWP app from your PC manually helps.

Also just tried this and it did not work. Same behavior has before. Build was selected already for the .NET standard library. – SolidSnake4444 Jan 23 '18 at 21:26

Not sure if it helps, but under Debug,Options,Debugging (General) I would disable the Enable Just My Code option
