+# Reproduction for sentry-dotnet#4902
+
+**Issue:** https://github.com/getsentry/sentry-dotnet/issues/4902
+
+## Description
+
+When upgrading from Sentry.AspNetCore SDK v5.16.2 to v6.0.0, a `TypeLoadException` occurs during application startup:
+
+```
+System.TypeLoadException: Could not load type 'BindableSentryExperimentalOptions' from assembly 'Sentry, Version=6.0.0.0'
+```
+
+This error happens when the SDK tries to bind configuration from `appsettings.json` using source-generated configuration binding.
+
+## Steps to Reproduce
+
+1. Install dependencies:
+   ```bash
+   dotnet restore
+   ```
+
+2. Run the application:
+   ```bash
+   dotnet run
+   ```
+
+## Expected Behavior
+
+The ASP.NET Core application should start successfully with Sentry SDK v6.0.0 configured, just as it did with v5.16.2.
+
+## Actual Behavior
+
+The application crashes during startup with:
+
+```
+Unhandled exception. System.TypeLoadException: Could not load type 'BindableSentryExperimentalOptions' from assembly 'Sentry, Version=6.0.0.0, Culture=neutral, PublicKeyToken=[REDACTED]'.
+   at Microsoft.Extensions.Configuration.Binder.SourceGeneration.<BindingExtensions_g>F69BD955067CC1B62D0915FD5271F3D3428E092A00BA3FDBE06C4BF5D97765D7A__BindingExtensions.BindCore(IConfiguration configuration, BindableSentryAspNetCoreOptions& instance, Boolean defaultValueIfNotFound, BinderOptions binderOptions)
+   at Microsoft.Extensions.Configuration.Binder.SourceGeneration.<BindingExtensions_g>F69BD955067CC1B62D0915FD5271F3D3428E092A00BA3FDBE06C4BF5D97765D7A__BindingExtensions.Bind_BindableSentryAspNetCoreOptions(IConfiguration configuration, Object instance)
+   at Sentry.AspNetCore.SentryAspNetCoreOptionsSetup.Configure(SentryAspNetCoreOptions options)
+```
+
+## Workaround
+
+Reverting to v5.16.2 resolves the issue:
+```bash
+dotnet add package Sentry.AspNetCore -v 5.16.2
+```
+
+## Environment
+
+- .NET SDK: 9.0.101
+- Sentry.AspNetCore: 6.0.0
+- OS: macOS
+
+## Notes
+
+This reproduction attempts to recreate the conditions described in the issue. The error may be environment-specific or related to build cache/AOT compilation settings. If the error doesn't reproduce immediately, try:
+
+1. Clean and rebuild:
+   ```bash
+   dotnet clean
+   rm -rf bin/ obj/
+   dotnet build
+   ```
+
+2. Check if you have any global.json or Directory.Build.props files that might affect the build
+
+3. The issue mentions MAUI workloads were installed - try with/without MAUI workloads installed
+
+The issue reporter confirmed that downgrading to v5.16.2 fixes the problem, suggesting this is a regression in v6.0.0 related to the source-generated configuration binding for `BindableSentryExperimentalOptions`.
