Details about Problem

NuGet product used: NuGet.exe

Product version: latest

Worked before? If so, with which NuGet version: none.

Repro steps and/or sample project

Proposal:
Add the project type nfproj to the list of supportedProjectExtensions in NuGet.Client/src/NuGet.Clients/NuGet.CommandLine/Common/ProjectHelper.cs
A PR can be raised if required.

Further explanation:
.NET nanoFramework (https://dotnetfoundation.org/projects/nanoframework) is an OSS platform that enables the writing of managed code applications for constrained embedded devices. It is supported by the .NET foundation.
.NET nanoFramework uses nuget packages extensively, however, due to a lack of support in VS for extensibility to have sub-projects in a given language (C#), we could not use the standard csproj type and have had to differentiate our projects by using a nfproj file extension.
When performing automated dependency updates, currently nuget CLI does not recognise this extension and we have to perform a workaround of scripting the rename of these projects to be the standard csproj in order to run tasks like nuget update, and then reverse the rename for compatibility with VS.
This is far from ideal, and by adding support for the extension in nuget, it would alleviate a number of complex workarounds.

due to a lack of support in VS for extensibility to have sub-projects in a given language (C#)

Many moons ago Visual Studio allowed to extend common project types like C# with sub-types. Please consider to take a look at ProjectTypeGuids MSBuild property. It allows you to instruct the project system to "flavor" a common project type with a custom extension UI/logic. This all applies to VS Extensibility area (VS Extensions etc).

Have tried that (on the scope of the project that @networkfusion mentions) without success.
Ended up having to use a different extension to accomplish this, which took us here.
To this date, and to the best of my knowledge, this is still not possible. See here

@networkfusion PRs welcome, then! Thank you :)

@zkat awesome! I'll be tackling this.

Now that we are at it, can we also discuss adding a TFM for .NET nanoFramework?
I've started a discussion about this in the .NET repo. Please see here.
