I'm trying to build a Portable Class Library using ANTLR4. I've added the necessary packages and in a normal project VS allows me to add any of the ANTLR items in the normal add new item way. I do not get the same list when I try to add a new item to a portable class library?
Not sure why it should not allow this?

I create a solution with 4 projects. One of them VSIX project, the other is Project Template and 2 of them are Item template. I want to create VSIX because all team use it. Exporting directly item template from visual studio working fine, but it is not good solution for team-works.
I use C# 10 version at my project. I want to create this template to targeting C# 10 language version. However in list there is only .NET Framework 4.8. So in this case, I cannot use record type or other new things.
How can I create a Visual Studio extension for .NET 6? How I target that or is there another way?
I use Visual Studio 2022.
Visual Studio 2022 targets .NET Framework, so you cannot write a VSIX targeting .NET 6 and have it install into VS2022.
That said, if you want to use newer C# features in .NET Framework projects, you can create an SDK-style project and manually change the .csproj file to have TargetFramework net472 and set LangVersion to 10 or whatever you prefer. While this works, it's not a scenario that Microsoft supports.
Note that for VSIX projects this is currently a bit tricky to get working. An example can be found here, however that's quite a complex build so it will require a good level of familiarity with MSBuild to use it as a reference.
Once you have increase the language version, you will also need something like https://www.nuget.org/packages/IsExternalInit to make record types compile correctly for .NET Framework.
I am struggling with creating NuGet packages. I am using Visual Studio 2017 Community edition.
I have seen a couple of videos that show a "Pack" option on the menu when right-clicking the project in Solution Explorer. However, I do not have that option. Is this one of the features in the other (non-Community) versions of Visual Studio? I believe I have also seen a "create NuGet package on build" option mentioned somewhere. I cannot find that either.
I have tried various ways of using nuget, dotnet, and msbuild from the command line(s), but haven't had much success. Very frustrating.
Any help is appreciated.
If you really want to use Visual Studio, I would recommend installing an extension that helps you with that problem. For example, this one. The options people have in videos depend on the extensions they have installed. For you, it is the same.
Alternatively, just use the command-line tooling for this as explained here or for .NET Core here or here.
dotnet/msbuild pack is only available for SDK-style projects, but I believe works for all versions of Visual Studio, as well as on the command line. .NET Core introduced these SDK-style projects, which can be identified by <Project Sdk="Microsoft.NET.Sdk">. If your project (.csproj if it's a C# project) doesn't have the Sdk property or import Microsoft.NET.Sdk in either of the two other ways, then it's not an SDK style project and doesn't support packing in this way. Another obvious difference between the two styles of projects is that SDK projects are only a few lines long from the new project template and don't list files in the project, whereas old style projects are typically a full screen long, even from a new project template with only a single class file, and it does list individual files in the project. If you want to continue with this project type, you'll need to use nuget.exe pack and you'll probably want to create a .nuspec file to define some of the package metadata.
However, using SDK style projects is the future, it just takes time for all of Microsoft's existing project types to migrate. It's much simpler to use, so personally I would avoid old style projects unless you're using a project type (like ASP.NET, not ASP.NET Core) that doesn't support it.
All of this is confusing for anyone new to the .NET ecosystem. My recommendation is 1. when you install Visual Studio, when making your workload selections, make sure in the component list that .NET Core is selected, whatever the newest version of .NET Core that is available at the time of installation. When creating a new project in Visual Studio, always select the .NET Core version, or .NET Standard version of any new project template, even if you want to target the (Windows) .NET Framework, in which case you edit the .csproj and change <TargetFramework>netstandard2.0</TargetFramework> to <TargetFramework>net45</TargetFramework>, although I would recommend multi-targeting possible by adding a s to the element name and using a semi-colon separated list: <TargetFrameworks>net45;netstandard2.0</TargetFrameworks>. So, avoid the "Class Library (.NET Framework)" template, instead use "Class Library (.NET Standard)" and then change the target if you have to.
#zivkan led me down the right path. Changing my project types to .Net Core from .Net Framework made all the options I mentioned in my original post available. No extensions were needed.
My .Net Core class library project now has the Pack and Publish options available on the project's context menu. In addition, there is a another tab (Package) on the project properties page. On that page there is a "Generate NuGet package on build" option along with version, name, tags and other properties.
I have done much .Net framework development, but have been ignoring .Net Core and the newer options. I guess I need to dig in and learn about them.
As the title says, is this currently an option? As can be seen in the screenshot, I don't see an option for creating a crossplatform project in Visual Studio. Is there a way around this i.e. is the cross-platform option just there for conveniently setting up the project structure? If so, how should I do this?
The references others have posted are good, except that not all those projects are .Net Standard 2.0, so if you use them, you will need to upgrade later. But even without a current template, creating a Xamarin Forms F# solution is not hard:
Create a new .Net Standard C# Xamarin.Forms project. Delete the .Net Standard C# library, leaving the platform-specific parts.
Add a .Net Standard 2.0 F# library, install the Xamarin.Forms package, and connect the platform projects to it.
Define an App class in this library:
type SomeNamespace.App() =
inherit Xamarin.Forms.Application()
do base.MainPage <- ...
Refer to this in the (C#) platform projects: LoadApplication(new SomeNamespace.App());
I see that MS has documentation on how to implement nesting projects when implementing new project types. While this looks do-able, I'd rather not write and maintain my own VS extension if I can avoid doing so. Is there any "generic" project type already implemented by some extension that will allow project nesting? The idea would be that the parent project does nothing but include its children and allow building, adding references, etc.
Managed Package Framework for Projects is for Visual Studio 2013 and includes "a project system that supports nesting" (see the NestedProject sample). I have not tried it myself, though I did look through it a while back (the VS 2010 version) and it has thorough documentation.
It may or may not be as extensive as what you are looking for. From the overview in the documentation:
Creating a new project type in Visual Studio is complex task. Using MPF_Proj is a good starting point for creating custom project types in Visual Studio written in managed code but there are limitations that would have to be considered before using the framework.
MPF_Proj is not a .NET library. It is rather a framework of source files (classes, utilities etc.) that can be included in a VSPackage project.
I use many custom build tools in visual studio 2010 for generating protocol buffer code. I'm curious if there's a way to create a template for this custom build tool so that I can just apply it to any .proto files I create? I'm using native c++ and I know there's a plugin for the .net version to do something similar but it's not appropriate for my uses.
