Fixes Code Analysis issues for C# templates

[curia-damiano]

In my project I have enabled code analysis and found a couple of issues. I would like to contribute updating the templates to benefit everyone.

I guess these problems apply to F# templates too,may you add these fixes for them also?

[curia-damiano]

I'm sorry but I really don't know F#...

I don't think waring suppressions should be in code, that just adds noise and most don't use analyzers that report these. What could maybe make sense is to set the "mark members as static" as ignored in the csproj. As this almost always reports wrongly on ViewModels

[Mrxx99]

There are also some indentation changes that look wrong

[Takoooooo]

Generally i am ok with everything besides identation changes,can they be reverted? I will add these changes to F# templates after that

[curia-damiano]

sorry I use tabs on my machine. I will work on this later

About the Gretting variable, another option is to make it static, but probably this would change the meaning of the view model.

Or it can returns some non-static string
