## Description{% #description %}

This rule prohibits using `ConfigureAwaitOptions.SuppressThrowing` directly on instances of `Task<T>`. The `SuppressThrowing` option is intended to be applied only on non-generic `Task` objects. Applying it on `Task<T>` can lead to unexpected behavior or runtime issues because `Task<T>` handles exceptions differently.

To comply with this rule, explicitly cast `Task<T>` instances to `Task` before calling `ConfigureAwait(ConfigureAwaitOptions.SuppressThrowing)`. For example: `((Task)t).ConfigureAwait(ConfigureAwaitOptions.SuppressThrowing);`. This approach ensures the suppress throwing option is applied correctly without affecting the generic task's exception handling.

## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```csharp
Task<int> t = new Task<int>(() => 1);
(Task)t.ConfigureAwait(ConfigureAwaitOptions.SuppressThrowing);
```

## Compliant Code Examples{% #compliant-code-examples %}

```csharp
Task<int> t = new Task<int>(() => 1);
((Task)t).ConfigureAwait(ConfigureAwaitOptions.SuppressThrowing);
```
