Controls not rendering in UWP Release Mode

Hi, 

I'm using MVVMCross in my Xamarin Forms UWP project and everything works in Debug mode, but when set to Release mode, syncfusion controls are not rendered.

I already included the assemblies like this:

protected override void OnLaunched(LaunchActivatedEventArgs activationArgs)
        {
            base.OnLaunched(activationArgs);

            List<Assembly> assembliesToInclude = new List<Assembly>();

            assembliesToInclude.Add(typeof(Syncfusion.SfDataGrid.XForms.UWP.SfDataGridRenderer).GetTypeInfo().Assembly);
            assembliesToInclude.Add(typeof(Syncfusion.SfChart.XForms.UWP.SfChartRenderer).GetTypeInfo().Assembly);
            assembliesToInclude.Add(typeof(Syncfusion.XForms.UWP.ProgressBar.SfLinearProgressRenderer).GetTypeInfo().Assembly);
            assembliesToInclude.Add(typeof(Syncfusion.XForms.UWP.ProgressBar.SfCircularProgressBarRenderer).GetTypeInfo().Assembly);

            Xamarin.Forms.Forms.Init(activationArgs, assembliesToInclude);

        }

Am i missing something?

I have a similar project that uses Prism and that one works fine, but i can't figure out why it's not working with MVVM Cross.

Thanks in advance for your help.

Best regards,
Diego Roses.

Hi Diego Roses, 
 
Greetings from Syncfusion. 
 
We have analyzed your query, and can you please ensure us once whether you have used the same code for including the assemblies, as in below link, 
 
Please refer the below link for running app in release mode for more details, 
 
 
If the above does not resolve the reported issue, can you please provide us the following details which will be helpful for us to analyze and to provide the better solution at earlier? 
·       Please ensure us whether the Compile with Native Tool chain is enabled or not when build application in release mode. 
·       Can you please share the Xamarin.Forms version and SfChart version details? 
·       Can you please ensure whether the other Syncfusion control like DataGrid, ProgressBar were too not rendered other than the Chart in release mode? 
·       Please let us know whether you are facing any crash while run in release mode using MVVMCross. 
 
Regards, 
Devakumar D

Hi, 

As you can see in the code I posted in the first message, I use the same code to include the assemblies, except  if (rootFrame == null) as it looks like is not needed in MVVMCross. Anyway, i tried adding the rootFrame stuff with the same result.

Regarding Native Tool chain, it is enabled:

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|x86'">
    <OutputPath>bin\x86\Release\</OutputPath>
    <DefineConstants>TRACE;NETFX_CORE;WINDOWS_UWP</DefineConstants>
    <Optimize>true</Optimize>
    <NoWarn>;2008</NoWarn>
    <DebugType>pdbonly</DebugType>
    <PlatformTarget>x86</PlatformTarget>
    <UseVSHostingProcess>false</UseVSHostingProcess>
    <ErrorReport>prompt</ErrorReport>
    <Prefer32Bit>true</Prefer32Bit>
    <UseDotNetNativeToolchain>true</UseDotNetNativeToolchain>
  </PropertyGroup>

Xamarin Forms version: 4.5.0.657
SfChart version: 18.1.0.45 (also for SfDataGrid and SfProgressBar)

None of the Syncfusion controls are rendering in release mode. All of them shows a blank space instead.

I have all exceptions turned on and everything seems to be running smooth with MVVMCross.

Thank you for your support!

Best regards,
Diego

Hi,

I've prepared a sample project using MVVMCross, where you can see an empty chart that is rendered in debug and not rendered in release.

As this is a public forum, I removed my SyncFusion license text. 

I hope this help to solve the issue. Please let me know if you need something else from my side.

Regards,
Diego

Hi Diego Roses, 
 
We are really appreciating your patience.  
 
In order to render the syncfusion controls with MVVMCross 6.1.2 and above version, please refer the Syncfusion control renderer as per in below code snippet 
 
[C#] 
 
namespace Syncfusion_Sample.UWP 
{ 
    public abstract class UWPApplication : MvxWindowsApplication<Setup, Core.App, FormsUI.App, MainPage> 
    { 
 
    } 
 
    public class Setup : MvxFormsWindowsSetup<Core.App, FormsUI.App> 
    { 
        public override IEnumerable<Assembly> GetViewAssemblies() 
        { 
            var customAssemblies = new List<Assembly>() 
        { 
            typeof(Syncfusion.SfChart.XForms.UWP.SfChartRenderer).GetTypeInfo().Assembly 
        }; 
            customAssemblies.AddRange(base.GetViewAssemblies()); 
            return customAssemblies; 
        } 
    } 
} 
 
Instead of applying that in  
 
  protected override void OnLaunched(LaunchActivatedEventArgs activationArgs) 
        { 
            base.OnLaunched(activationArgs); 
 
 
            List<Assembly> assembliesToInclude = new List<Assembly>(); 
 
            //assembliesToInclude.Add(typeof(Syncfusion.SfDataGrid.XForms.UWP.SfDataGridRenderer).GetTypeInfo().Assembly); 
            assembliesToInclude.Add(typeof(Syncfusion.SfChart.XForms.UWP.SfChartRenderer).GetTypeInfo().Assembly); 
            //assembliesToInclude.Add(typeof(Syncfusion.XForms.UWP.ProgressBar.SfLinearProgressRenderer).GetTypeInfo().Assembly); 
            //assembliesToInclude.Add(typeof(Syncfusion.XForms.UWP.ProgressBar.SfCircularProgressBarRenderer).GetTypeInfo().Assembly); 
 
            Xamarin.Forms.Forms.Init(activationArgs, assembliesToInclude); 
 
        } 
 
 
 
Release mode update: 
 
 
 
Regards, 
Hemalatha M.
