我通过 VS2015 创建了一个简单的 Visual Studio 扩展。 构建项目并开始调试。出现Visual Studio的实验实例。
在实验窗口中，我可以在工具菜单中看到扩展名。但我在解决方案资源管理器中或右键单击任何 .cs 文件时都看不到。
我已经在线安装了一个扩展“style cop”，我可以在工具中看到它，也可以通过右键单击任何 .cs 文件来查看它。我实际上想通过右键单击 .cs 文件来运行该扩展
我错过了什么吗？

我错过了什么吗？
如果您想在解决方案资源管理器的工具菜单和上下文菜单上添加命令菜单，您需要为解决方案资源管理器添加新的命令菜单，请右键单击项目 -> 添加 -> 新项目 -> 可扩展性 -> 自定义命令-> 添加。
然后像这样修改你的 vsct 文件：
<?xml version="1.0" encoding="utf-8"?>
<CommandTable xmlns="http://schemas.microsoft.com/VisualStudio/2005-10-18/CommandTable" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<!-- This is the file that defines the actual layout and type of the commands.
It is divided in different sections (e.g. command definition, command
placement, ...), with each defining a specific set of properties.
See the comment before each section for more details about how to
use it. -->
<!-- The VSCT compiler (the tool that translates this file into the binary
format that VisualStudio will consume) has the ability to run a preprocessor
on the vsct file; this preprocessor is (usually) the C++ preprocessor, so
it is possible to define includes and macros with the same syntax used
in C++ files. Using this ability of the compiler here, we include some files
defining some of the constants that we will use inside the file. -->
<!--This is the file that defines the IDs for all the commands exposed by VisualStudio. -->
<Extern href="stdidcmd.h" />
<!--This header contains the command ids for the menus provided by the shell. -->
<Extern href="vsshlids.h" />
<!--The Commands section is where commands, menus, and menu groups are defined.
This section uses a Guid to identify the package that provides the command defined inside it. -->
<Commands package="guidFirstCommandPackage">
<!-- Inside this section we have different sub-sections: one for the menus, another
for the menu groups, one for the buttons (the actual commands), one for the combos
and the last one for the bitmaps used. Each element is identified by a command id that
is a unique pair of guid and numeric identifier; the guid part of the identifier is usually
called "command set" and is used to group different command inside a logically related
group; your package should define its own command set in order to avoid collisions
with command ids defined by other packages. -->
<!-- In this section you can define new menu groups. A menu group is a container for
other menus or buttons (commands); from a visual point of view you can see the
group as the part of a menu contained between two lines. The parent of a group
must be a menu. -->
<Groups>
<Group guid="guidFirstCommandPackageCmdSet" id="MyMenuGroup" priority="0x0600">
<Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS" />

<!--Buttons section. -->
<!--This section defines the elements the user can interact with, like a menu command or a button
or combo box in a toolbar. -->
<Buttons>
<!--To define a menu group you have to specify its ID, the parent menu and its display priority.
The command is visible and enabled by default. If you need to change the visibility, status, etc, you can use
the CommandFlag node.
You can add more than one CommandFlag node e.g.:
<CommandFlag>DefaultInvisible</CommandFlag>
<CommandFlag>DynamicVisibility</CommandFlag>
If you do not want an image next to your command, remove the Icon node /> -->

<!--The bitmaps section is used to define the bitmaps that are used for the commands.-->
<Bitmaps>
<!-- The bitmap id is defined in a way that is a little bit different from the others:
the declaration starts with a guid for the bitmap strip, then there is the resource id of the
bitmap strip containing the bitmaps and then there are the numeric ids of the elements used
inside a button definition. An important aspect of this declaration is that the element id
must be the actual index (1-based) of the bitmap inside the bitmap strip. -->

【讨论】：
您必须更改 .vsct 文件中的 id。
<Group guid="guidChangesetViewerCommandPackageCmdSet" id="MyMenuGroup" priority="0x0600">
<Parent guid="guidSHLMainMenu" id="IDM_VS_TOOL_PROJWIN"/>
</Group>
Here是visual studio不同窗口的guid和id列表。
