Hi, thanks for posting!
Sorry, this is a known problem at the moment. You can work around this creating a config file with the 'IgnoreThisComponentCompletely' property set. For example, under NCrunch V3 you would create a file adjacent to your project file with the name PROJECT.v3.ncrunchproject and the contents:
<ProjectConfiguration>
<Settings>
<IgnoreThisComponentCompletely>True</IgnoreThisComponentCompletely>
</Settings>
</ProjectConfiguration>
Under V2, you would create a file called PROJECT.v2.ncrunchproject and the contents:
<ProjectConfiguration>
<IgnoreThisComponentCompletely>true</IgnoreThisComponentCompletely>
</ProjectConfiguration>
