Anybody home? VM-ing .NET4.6.2 to process .NET4.5.2 assembly

[jspraul]

I am trying to process a .NET 4.5.2 assembly using the latest source code and not making progress. I will report back as I try older versions to see how things worked back when #3 was hip.

I have downloaded Microsoft Visual Studio Express 2015 for Windows Desktop (most recent I could find free for commercial use). This was a bit tough to find since trying to get it from the official source pushes the Community Edition (possibly even the web installers?).

I then downloaded and installed .NET 4.6.2 and the .NET 4.6.2 targeting/dev pack. I made a bunch of changes to the App/packages.config files (no longer NuGet-ing most System stuff to avoid redirect causing errors), and pointed Refl.Asembly_Csc to v2. I can put this in a pull request if desired, as the actual LINQ rewriting appears to work, with the following logged:

  Rewriting LINQ to procedural code...
  Rewritten 156 LINQ queries in 135 methods as procedural code.

However, when it comes time to write the new output, I get the following error related to the v2 change (need to create a "dummyCompiler" where there are a bunch of commented out examples):

  System.InvalidCastException: Unable to cast object of type 'Microsoft.CodeAnalysis.CSharp.CommandLine.Csc' to type 'Microsoft.CodeAnalysis.CommonCompiler'.

C:\Program Files (x86)\MSBuild\14.0\bin\Microsoft.CSharp.Core.targets(67,5): error MSB6006: "csc.exe" exited with code 1.

PS. When using msbuild per #3 to get the stack traces, searching for Task "csc" jumps to the useful info. Simplifying this process would make troubleshooting a lot easier.
