Template engine in .NET 4 console app

[MotoWilliams]

In reference to this topic 'Template engine'
http://groups.google.com/group/spark-dev/browse_thread/thread/9411da77994c801c
and 'Using Spark as a general purpose template engine'
http://whereslou.com/2008/12/16/using-spark-as-a-general-purpose-template-engine

Works fine when targeting .NET 3.5. When trying to run the code in
VS2010 targeting .NET 4 it runs into problems with mscorlib.

Any ideas?

Now that .NET 4 has RTM'ed - could someone from the dev team comment,
verify and or suggest a solution?

I'll need to look into that. Will reply as anything is learned.

If you're setting the version CompilerOptions within BatchCompiler.cs
at line 60 from 3.5 to 4.0 to look like this:

var providerOptions = new Dictionary<string, string>
{ { "CompilerVersion", "v4.0" } };

it will works like a charm.

The root of the problem is that the running .Net version is 4.0 and
mscorlib is added by default as a referenced assembly. When specifying
3.5 it causes a conflict.

Maybe this problem can be mitigated by checking the hosting
environment's version and use that as a setting for CompilerVersion
property in batch compiler.

Would this do the trick?

var version = string.Format("v{0}.{1}",
System.Environment.Version.Major, System.Environment.Version.Minor);

var providerOptions = new Dictionary<string, string> { {

"CompilerVersion", version } };

There is a problem with that.

When you targeting .Net 3.5 from an application this version number
will be 2.0 and not 3.5!!!

Framework version is NOT runtime version, so this does not help us
here.
