Including The Task In Your Project's Project File Afterwards you will get following build error:
The "FSharpLintTask" task failed unexpectedly.
System.IO.FileNotFoundException: Could not load file or assembly 'FSharpLint.Application, Version=0.1.11.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
File name: 'FSharpLint.Application, Version=0.1.11.0, Culture=neutral, PublicKeyToken=null'
When executing any kind of build, NCrunch will always inject a special property that can be used to identify it during the build. The property is $(NCrunch) with a value of 1. Therefor you need to turn off FSharpLint while building with nChrunch. Anyway it has no sence :)
Use Condition="'$(NCrunch)' != '1'"
with MSBuild XML nodes to disable execution for nCrunch and see MyProject.fsproj
for more samples
