InvalidCastException when trying to add device context

[IasonasNikolaou]

Please mark the type framework used:

• [x ] Other: Maui

Please mark the type of the runtime used:

• [x ] .NET Framework

• Version: 6.0.5

Please mark the NuGet packages used:

• [ x] Sentry

Steps to reproduce the issue or link to a repository with a small reproducible code.
Add sentry to a maui or probably even a .net project. I don't think thats a maui related issue tbh.

I've got this piece of code in my Main which worked fine until i decided i also needed to add device info

SentrySdk.ConfigureScope(scope =>
            {
                scope.User = new User
                {
                    Id = "1",
                    Username = "Testuser",
                };
                scope.Contexts["os"] = new
                {
                    name = AndroidInfo.platform,
                    version = AndroidInfo.version,
                };
                scope.Contexts["device"] = new
                {
                    name = AndroidInfo.deviceName,
                    family = AndroidInfo.manufacturer,
                    model = AndroidInfo.device,
                    manufacturer = AndroidInfo.manufacturer,
                }; 
            });

"os" and "user" are working just fine on their own, however "device" returns this exception

[DOTNET] System.InvalidCastException: Specified cast is not valid.

[DOTNET]    at Sentry.SentryClient.DoSendEvent(SentryEvent event, Scope scope) in /_/src/Sentry/SentryClient.cs:line 201

I should note that all of these are strings and do have values.
If i try to add the device context as something else (ex:scope.Contexts["deviceinfo"]) it works just fine.
Is there any way to get around this error?

[IasonasNikolaou]

Upon further experimentation, if i cast the object when i add it to the contexts, it works.

using Sentry.Protocol;
.
.
.
 scope.Contexts["device"] = new Device
                {
                    Name = AndroidInfo.deviceName,
                    Family = AndroidInfo.manufacturer,
                    Model = AndroidInfo.device,
                    Manufacturer = AndroidInfo.manufacturer,
                };

      scope.Contexts["device"] = new
                {
                    name = AndroidInfo.deviceName,
                    family = AndroidInfo.manufacturer,
                    model = AndroidInfo.device,
                    manufacturer = AndroidInfo.manufacturer,
                }; 

this is an anonymous type so i am not surprised it fails.

i think we need some type checking in GetOrCreate. i will take a look

[SimonCropp]

as an alternative is you can do this via

       SentrySdk.ConfigureScope(scope =>
        {
            var device = scope.Contexts.Device;
            device.Name = AndroidInfo.deviceName;
            device.family = AndroidInfo.manufacturer;
            device.model = AndroidInfo.device;
            device.manufacturer = AndroidInfo.manufacturer;
        });

@jaisonass - Thanks for reporting this issue with the InvalidCastException.

FYI - We are working on adding first-class support for both MAUI (#1651) and for Android (net6.0-android) in general. Both are coming very soon.

This will include device information like you are doing here, so some of your work will be redundant. You might just want to wait.

[SimonCropp]

@jaisonass closing this one. the better exception message will ship in the next release.

[IasonasNikolaou]

@SimonCropp Yep, thank you both for your time!
