Vnext Argument 1: cannot convert from 'string' to 'System.IO.Stream'

Question

I am trying to create a generic serializer withing a Vnext project and when I call the constructor for StreamWriter it throws this compiler error

Answer 1

Here is the Answer from davidfowl

Thats because it's not available on CoreCLR. Use new StringWriter(File.OpenWrite(path)) instead

For future reference where can I check if a function is available or not?

File issues on the https://github.com/dotnet/corefx repository. They will be able to clarify why things are missing in the new framework. I believe the reason this particular overload was removed was because of layering issues between the new packages.

The assembly that contains StreamWriter shouldn't be directly referencing FileStream:

new StreamReader(path)

actually does

new StreamReader(new FileStream(path, options)).
