+
+  We need to keep this basically up to date, as well as track the set of modifications we've made. Try to keep the formatting
+  similar to the original to reduce noise. In general try to only deviate from the CoreCompile target when we need to for
+  correctness.
+
+  We also want to avoid doubling up on things that don't make a ton of sense in the Razor views assembly, like
+  embedded files and resources, these are already present in the application's assembly.
+
+  Changes:
+    Name="RazorCoreCompile" and DependsOnTarget="RazorCoreGenerate"
+    
+    Replace @(Compile) with @(RazorCompile)
+    Replace @(_DebugSymbolsIntermediatePath) with @(_RazorDebugSymbolsIntermediatePath)
+    Replace @(IntermediateAssembly) with @(RazorIntermediateAssembly)
+    Replace @(ReferencePathWithRefAssemblies) with @(RazorReferencePath)
+
+    Set TargetType="$(OutputType)" to TargetType="Library" - Razor is always a .dll
+
+    Remove Returns="@(CscCommandLineArgs)"
+    Remove @(_CoreCompileResourceInputs)
+    Remove $(ApplicationIcon) $(Win32Resource) $(Win32Manifest)
+    Remove @(EmbeddedDocumentation) and @(EmbeddedFiles)
+    Remove @(CustomAdditionalCompileInputs) and @(CustomAdditionalCompileOutputs)
+    Remove @(DocFileItem)
+    Remove PdbFile="$(PdbFile)"
+    Remove OutputRefAssembly="@(IntermediateRefAssembly)"
+
+    Remove EmbedAllSources="$(EmbedAllSources)" - not supported by our supported version of MSBuild
+
+    Remove additional steps after calling CSC
+
+    Add our FileWrites after the call to CSC
