command line arguments during build are too long #56

Consider using a response file instead of generating a large command.

Referencing an asp.net core app already breaks the by causing an

C:\Users\martin.ullrich\.nuget\packages\codegeneration.roslyn.buildtime\0.4.11\build\CodeGeneration.Roslyn.BuildTime.targets(20,5): error MSB6003: The specified task executable "dotnet" could not be run. The filename or extension is too long 

The command-line for the "GenerateCodeFromAttributes" task is too long. Command-lines longer than 32000 characters are likely to fail. Try reducing the length of the command-line by breaking down the call to "GenerateCodeFromAttributes" into multiple calls with fewer parameters per call.

@AArnott I've created a replacement msbuild target to work around this (it creates a response file and reads the output file). do you think it is better to keep the msbuild task dll around or maybe migrate to pure msbuild?

Thanks for the report and diagnoses. I'm inclined to keep the MSBuild task around. Mostly in the hopes of one day MSBuild actually supporting doing all this in-proc so I don't have to spawn dotnet.exe.
