#2608: Await the call to FeatureBackgroundAsync

[laingsimon]

Ensure that calls to FeatureBackgroundAsync are awaited when called, i.e.

Instead of this

// ... snip ...
#line 4
    this.FeatureBackgroundAsync();
#line hidden
// ... snip ...

Generate this

// ... snip ...
#line 4
    await this.FeatureBackgroundAsync();
#line hidden
// ... snip ...

Types of changes

• Bug fix (non-breaking change which fixes an issue).
• New feature (non-breaking change which adds functionality).
• Breaking change (fix or feature that would cause existing functionality to not work as expected).
• Performance improvement
• Refactoring (so no functional change)
• Other (docs, build config, etc)

Checklist:

• I've added tests for my code. (most of the time mandatory)
• I have added an entry to the changelog. (mandatory)
• My change requires a change to the documentation.
• I have updated the documentation accordingly.

---

Note: I've not added tests or an entry to the change log for the following reasons:

• There are no existing tests for the UnitTestMethodGenerator; if you require them then i can have a look to create some
• I've not added an entry to the changelog as this fixes a change within the 4.0.16-beta version, as such it fixes an issue during the beta. Once again if this is required, please let me know and i'll add something in.

3. Rebuild client project
4. Observe a change to the built xxx.feature.cs file in client project
