[Blazor/WASM] Unable to enumerate over IEnumerable in the Watch Window

[RobertBouillon]

Describe the bug

You cannot view the results of an IEnumerable in the watch window.

To Reproduce

1. Create a new Blazor / WASM project in VS 2019
2. Add a new class called Bar using the code below
3. Update FetchData.razor using the code below.
4. Add a breakpoint after the foo variable is initialized
5. Add foo to the watch window
6. Expand the foo variable in the watch window
7. Expand the Sequence property (It's IEnumerable<int>)

Expected Results

An option will appear in the watch window called "Results View" that will execute the enumerable and display the results

Actual Results

No option exists to view the contents of the IEnumerable property.

WASM Output

.NET Core Output

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.
