[Enhancement]: Upgrade CodeDOM provider by default

[bdukes]

Is there an existing issue for this?

• I have searched the existing issues

Description of problem

The ASP.NET runtime compiler defaults to an older version of the C# and VB.NET compilers. DNN includes a package which updates the compilers, but it isn't installed by default.

Description of solution

Install the CodeDOM provider package by default on installs and upgrades.

Description of alternatives considered

Continue to provide it as an optional package.

Anything else?

With the provider installed, this Razor script renders correctly, <h1>@(Dnn?.ActiveModule?.ModuleID)</h1>, whereas it gives an error without the provider being installed (because the ?. operator was introduced in C# 6, and the ASP.NET compiler only supports C# 5 by default).

This package is currently optional because previous versions of DNN found examples of installations failing on GoDaddy hosting, since the package installs csc.exe and vbc.exe into the bin folder. Our expectation is that testing for DNN 10 will reveal any incompatibilities with currently used hosting providers.

This is fantastic! I am strongly in favor of this and looking forward to no longer having to do this additional setup step after every DNN install. Cheers!!

Merged into v10 branch.

Yes, the few in odd hosting environments that can't allow this, users can just delete that zip or rename to .resoruces as a workaround...

The needs of the many outweigh the needs of the few....
