I have a MAUI desktop app that I have built using MAUI and Telerik controls,
It runs on Windows Desktop and in Windows deployed via the Microsoft Store,
It runs via Visual Studio on a Mac (Apple M2 Max)
However the UI does not load when running on the same Mac, deployed via TestFlight
I have systematically removed code from the project until I removed the Telerik controls.
I have this in the MauiProgram
var builder = MauiApp.CreateBuilder();
builder
.UseMauiApp<App>()
.UseTelerik()
.UseMauiCommunityToolkit()
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
});This at the ContentPage tag:
xmlns:telerik="http://schemas.telerik.com/2022/xaml/maui"
and this Telerik component code (within a grid and HorizontalStackLayout with other standard controls):
<telerik:RadComboBox x:Name="WorkflowsComboBox"
TextColor="White"
HorizontalOptions="Start"
DisplayMemberPath="Name"
Placeholder="(select workflow)"
PlaceholderColor="Black"
BackgroundColor="Transparent"
WidthRequest="600"
Padding="0,3,0,0"
Margin="10,3,10,3"
BorderColor="#644E88">
</telerik:RadComboBox>The app runs without the above code and UI hangs with the above code?
Latest Visual Studio Mac version with the automatic workflows installed.
packages:
<ItemGroup>
<PackageReference Include="CommunityToolkit.Maui" Version="5.2.0" />
<PackageReference Include="CommunityToolkit.Mvvm" Version="8.2.1" />
<PackageReference Include="Microsoft.AspNetCore.SignalR.Client" Version="7.0.5" />
<PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="7.0.0" />
<PackageReference Include="Polly.Extensions.Http" Version="3.0.0" />
<PackageReference Include="Telerik.UI.for.Maui" Version="5.2.0" />
<PackageReference Include="NLog.Targets.MauiLog" Version="5.*" />
<PackageReference Include="NLog.Extensions.Logging" Version="5.*" />
</ItemGroup>Any ideas?
Note: The app will need to be run via TestFlight.
I am not getting any crash reports or error messages and trying to catch exceptions everywhere.
The UI simply doesnt show up, the ViewModel initializes, and runs code, including tasks on a timer (before removing most of that code to get the app working)
Please advise.

Hi Mark,
The solution is to explicitly choose .NET MAUI 7.0.86 for the project instead of implicitly using v.7.0.92.
There must be a bug in .NET MAUI 7.0.92 that is causing this, so I have opened a Bug Report for the team to investigate further. It's likely Microsoft changed something in the latest SDK that we have to address if/when we build on top of 7.0.92+

Hi Mark, I saw your comment on a forum post about the RadListView and them moved it here. We'll continue the conversation here.
To make sure I understand correctly, this only happens when in TestFlight and Release build work locally? (Debug builds have optimizations turned off, so this isn't a good representation of a release deployment). I don't see anything wrong with the code itself.
Can you please check your build settings and make sure the linker is not stripping out external assemblies? The LinkerBehavior can sometimes remove code when build in Release mode, try setting it to SdkOnly
Thanks for your reply.
I have seen that setting (and may have tried it in the 90+ uploads to TesfFlight) when trying many other things, but will try it and report back.
You do mean changing:
<MtouchLink>Full</MtouchLink>
to
<MtouchLink>SdkOnly</
I suspect it is a build thing and also suspect that I have added many settings that might have broken things in trying to get things working...
I am publishing the app via Visual Studio using the following publishing profile and have included the project file, in case you spto anything else obvious.
Thanks.
and this is the project file (showing <MtouchLink>Full</MtouchLink>) I will change that...

I updated the project release settings to:

Hi Mark, correct "Full" will strip everything possible it can from the final assembly. This is intentional because it removes unused code form the final package. However there is a downside that can happen when using 3rd party libraries... if the compiler cannot detect that reference, then the linker will remove that code from the final app causing runtime errors.
It is really weird that you're getting an exception after easing the linker's restrictions. It's usually the opposite. What happens if you set it to "None"?
The stack hints that the problem is with SkiaSharp. I will work on setting up my TestFlight account again to attempt to reproduce this, but it might take a couple days. I'll also ask the devs for any insight,
Priority Note: I've noticed you've never opened a support ticket, so I'm not sure if you knew it was available. In the future, for time sensitive and/or non-community focused issues, I recommend opening a Support Ticket instead of a forum post. This is at 3x faster for response time. Of course, if you want to have the conversation in public to share the information with the rest of the community, this is the place to do it, it just may take more time to reply because tickets have a higher priority for the engineers.
I do have this Warning in Visual Studio
I believe this something included with Telerik?
I will submit a ticket in future..
Okay, so that explains why SkiaSharp crashes. I'll continue investigating full linking with the RadDatePicker. Are you able to share the XAML for the page that contains it? You can strip out the rest of the UI, I just need to see the relationship between the picker and it's parents. For example, this is the lrelevant part for me: DatePicker > in a Grid (with RowDefintion Height=Auto) > ContentPage
Technically speaking, I don't see why the linker would interfere with the RadDatePicker. Normally it's only a problem for native controls that are loaded with a MAUI handler (RadListView, Chart, etc). The RadDatePicker is a pure .NET MAUI component and shouldn't be affected, but I'll know more once I talk to the team and try to replicate in my TestFlight.
Mark, can you please run the following command in the CLI (PowerShell, Terminal, any) to let me know what version of .NET MAUI is being used: dotnet workload list

--------------------------------------------------------------------
maui-maccatalyst 7.0.92/7.0.100 SDK 7.0.300
maui-ios 7.0.92/7.0.100 SDK 7.0.300
maui-android 7.0.92/7.0.100 SDK 7.0.300
That's higher than the one we used to build UI for Maui 2023.2 with, and I'm starting to suspect this might be related. We built with 7.0.56 so that it doesn't force customers to upgrade.
We do have a service pack release coming out on Wednesday. I will test with both the current one you're using now and get it to replicate. Once that's broken, I will try again with the upcoming to release to see if that resolves it.
It will take me a day or two to get TestFlight and publishing done with the results. I have to regenerate all my certs, and setup TestFlight again. I cannot use the official Telerik product certitificates for this, so I appreciate your patience and understanding while I work on this.
In the meantime, you can explicitly set the MauiVersion in your csproj and do a Clean and Rebuild. This will build your app with that specific version.
Put this in the opening PropertyGroup in the csproj:
<MauiVersion>7.0.86</MauiVersion> (or <MauiVersion>7.0.56</MauiVersion> if you want to try with an earlier version)
Thanks for doing that, appreciated!
Mark
Can you please also let me know what the results were for the following tests, this will help guide my investigation
I do appreciate and understand that each time you test, you have to build a release, publish to Testflight and re-install it. So I don't ask these things lightly.
Hi,
ok, tried changing to :
<MauiVersion>7.0.56</MauiVersion>But got this error: (not sure those workloads are still installed and would need to look how to do that)
Changed to:
<MauiVersion>7.0.86</MauiVersion>
cleaned, removed bin / obj folders, restored Nugets and rebuilt / published, and updated to TestFlight..
Yes, this version worked! (95th time lucky.. this is the real number)
ok, so I had tried with a couple of previous versions of the Telerik controls, but had always updated VS and the workloads whener coming back to this project to reduce any issue..
I guess we need to watch these versions... Not sure if it's a pure versioning issue or something else?
This is a good step forward and I can at least reconstruct the project for continued tests on both Windows and Mac..
not sure you if you still need to do anything now, but I will lookout for the newer versions and consider the MauiVersion...
Thanks for your help.
Hi Mark, as you've noticed, I've posted the solution as an Answer to this thread. This will allow anyone else who is having the same problem find this conversation more easily. I'm really happy to see that you're past the issue and can move forward.
As promised, I opened a bug report on your behalf => DatePicker: Not Visible on MacCatalyst when using Maui 7.0.92 (telerik.com). You will automatically get a notification when we update its status or post a message, so you don't have to manually check for updates.
Have a great weekend!
