Support Xamarin Android

[avinabmalla]

I was unable to add the NuGet package to a Xamarin Android project. It was strange, as I could add the numerics package but not this one. Mybe this project was created as a regular class library instead of a portable one.

Thanks!

I have created a portable class library for mathnet-filtering that passed the current unit tests and works in my application. Would the mathnet team be interested in a pull request for this?

I'd certainly accept a PR to add support for a PCL build. To keep it maintainable it should follow the same style as the other Math.NET projects do (mostly Numerics) though, e.g. such that the release process is fully automated.

Would you prefer a separate PCL project to be added to the current solution, or that the PCL replaces the current project?

[cdrnet]

I think i the medium term we'd want to target both .Net Framework (pure; v4 or higher) and .Net Standard v2.0. Until the tooling around .Net Standard is ready, having two projects, one for .Net 4 and one for a PCL would make sense, and is also in line with the other Math.NET Projects (e.g. Numerics: PCL project files, .All solution including them, , build package, build variants, etc)

[cdrnet]

I'd propose to support only 1 PCL profile here, of course, not 5 different ones like Numerics. Profile 259 could be a good choice as it transfers nicely to .Net Standard.

Ok. So if I forked the master, added the PCL project to the solution and did a PR, would anything else need to change?

[cdrnet]

That would be fine - I can take care of the rest (mostly extending build.fsx). Thanks!

[ghost]

Ok. I'll get on it.

@cdrnet How the PR going? Anything I can do to help?

[cdrnet]

Math.NET Filtering - finally - supports the portable profile 259 (and .Net 3.5), since v0.3.0.

@tura08 thanks a lot for putting work into this and providing a pull request. Unfortunately I was not clear enough what I meant with adding a project (this is a learning for me - I meant just the project file, pointing to the same sources) and I could therefore not merge the pull request as it would have deviated from the Math.NET approach, which would make this project unmaintainable for me.

@cdrnet not a problem, glad to help. Out of curiosity, what did you adjust in the project file to get it to build as PCL? I can't see anything in the latest commit.

[cdrnet]

@tura08 ah, forgot to push. It is there now.
