Raygun4Net.NetCore provider sends empty telemetry when .Net trimming is enabled

[gplwhite]

Describe the bug
When a .Net Core application is published with trimming enabled, the telemetry messages sent to the Raygun api only contain the OccurredOn timestamp. No other data is sent.
The Raw Data tab in the Raygun dashboard shows the following was received:

{
  "OccurredOn": "2025-08-07T23:12:23.8553019Z"
}

To Reproduce
Steps to reproduce the behavior:

1. Create a new .Net console application dotnet new console
2. Add the Raygun Nuget package dotnet package add Mindscape.Raygun4Net.NetCore
3. Add the following lines to the Program.cs

using Mindscape.Raygun4Net;
await new RaygunClient("API KEY HERE").SendAsync(new Exception("Log Message"));

5. Add the following entries to the project file to enable trimming

<PropertyGroup>	
	<PublishTrimmed>true</PublishTrimmed>
	<TrimMode>full</TrimMode>
</PropertyGroup>

4. Compile and publish the application dotnet publish
5. Run the resulting executable
   Expected behavior
   A full set of metadata (including MachineName, VersionNumber, Exception information, Environment data) should be captured by the Raygun client and sent to the Raygun api

Additional context
Changing the TrimMode to partial <TrimMode>partial</TrimMode> results in the correct telemetry being sent.

I think this is probably because the Json serialiser is using reflection to serialise the message payload before sending it to the API. I'm guessing that some of the reflection APIs are being trimmed away (or otherwise disabled) and the Json serialiser is no longer able to traverse the properties of the message payload.
