+# RSCG_Demeter
+Demeter Law : http://haacked.com/archive/2009/07/14/law-of-demeter-dot-counting.aspx/
+
+
+# Usage
+
+Add the package RSCG_Demeter to the csproj
+
+```xml
+	<ItemGroup>
+    <PackageReference Include="RSCG_Demeter" Version="2026.328.706" OutputItemType="Analyzer" ReferenceOutputAssembly="false"  />
+  </ItemGroup>
+```
+
+Then build the project - the analyzer will run and show the errors in the error list.
+
+## Export 
+
+Add this to the csproj
+
+```xml
+	<ItemGroup>
+		<CompilerVisibleProperty Include="RSCG_Demeter_GenerateFile" />
+	</ItemGroup>
+	<PropertyGroup>
+		<RSCG_Demeter_GenerateFile>../YourProjectName.csproj.txt</RSCG_Demeter_GenerateFile>
+	</PropertyGroup>
+
+```
+
+And the file YourProjectName.csproj.txt will be generated with the errors.
