When trying to run my tests in Visual Studio, I receive a Missing [assembly:GeneratorPlugin] attribute error. How can I solve this?

Sample output:

Missing [assembly:GeneratorPlugin] attribute in SpecFlow.Plus.Excel.SpecFlowPlugin.dll
#error TechTalk.SpecFlow.Generator
#error Server stack trace:
#error at TechTalk.SpecFlow.Generator.Plugins.GeneratorPluginLoader.LoadPlugin(PluginDescriptor pluginDescriptor)
...

If you are receiving this error, try setting the Generation Mode in SpecFlow to "OutOfProcess". To do so:

1. Select Tools | Options from the menu in Visual Studio.
2. Select SpecFlow from the list on the left.
3. Locate the Generation Mode setting and set it to "OutOfProcess".
