Answer 1

I had this same problem so I followed Will Huang's answer but created my own snippet. I will leave the code snippet below.

<?xml version="1.0" encoding="utf-8" ?>
<CodeSnippets >
    <CodeSnippet Format="1.0.0">
        <Header>
            <Title>mvcaction</Title>
            <Shortcut>mvcaction</Shortcut>
            <Description>Code snippet for an MVC Action</Description>
            <Author>Jordan Gregory-Wallis</Author>
            <SnippetTypes>
                <SnippetType>Expansion</SnippetType>
                <SnippetType>SurroundsWith</SnippetType>
            </SnippetTypes>
        </Header>
        <Snippet>
            <Declarations>
                <Literal>
                    <ID>name</ID>
                    <ToolTip>Action Name</ToolTip>
                    <Default>Action</Default>
                </Literal>
            </Declarations>
            <Code Language="csharp"><![CDATA[public ActionResult $name$()
    {
        return View();
    }]]>
            </Code>
        </Snippet>
    </CodeSnippet>
</CodeSnippets>

MVC4 snippets are supported in VS2017. MVC 4 is an optional component that's part of the web workload. If you don't have it installed and try to open an MVC 4 project it should prompt you to add the missing component to Visual Studio.

Support for MVC 4 is limited. We don't allow you to create new MVC 4 projects, but you can - Open existing MVC 4 projects - Scaffold controllers/views - Use snippets

EDIT MVC4 snippets will only show up for an MVC 4 project. The snippets are tied to the .csproj/.vbproj ProjectTypeGuid properties.

I think the mvcaction4 and mvcpostaction4 snippets has been removed from Visual Studio 2017.

All you can do is to import these snippets from Visual Studio 2015. Here is the steps you can do:

1. Assume you have already installed both Visual Studio 2015 and Visual Studio 2017.
2. Open Visual Studio 2017, then click menu [Tools] -> [Code Snippets Manager]
3. Switch Language to CSharp in the Code Snippets Manager window
4. Hit the Import button
5. Enter C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 4\Visual Studio 2015\Snippets\VC#\1033\ASP.NET MVC 4 and select all items ( mvcaction.snippet and mvcpostaction.snippet )
6. Hit Finish button to complete import.
