I just created a <a href="http://techninotes.blogspot.com/2016/08/fixing-cannot-find-wrapper-assembly-for.html">blog post</a> on this issue. The problem is that the Microsoft.mshtml.dll assembly in the Global Assembly Cache becomes unregistered from ActiveX during the upgrade process. To fix this issue, it is necessary to run "regasm" on the assembly:

<ol>
<li>Open an instance of "Developer Command Prompt for VS2013" (or whatever version of Visual Studio you happen to be using). Run it as Administrator by right-clicking the icon and selecting, "Run as Administrator."</li>
<li>Navigate to "C:\Windows\assembly\GAC\Microsoft.mshtml\7.0.3300.0__b03f5f7f11d50a3a." It is possible your path will vary. To verify, go to "C:\Windows\assembly\GAC\Microsoft.mshtml" and type "dir."</li>
<li>Once you are in the correct path, type <code>regasm Microsoft.mshtml.dll</code></li>
</ol>

blocks|key|3976772|text|我也遇到了同样的问题，我认为，至少在我的例子中，这个项目最初是一个Windows7上的VS2012项目，并且安装了一个主要的互操作程序集。当我删除和重新添加对MSHTML的引用并对文件进行区分时，唯一的区别是<WrapperTool>从primary更改为tlbimp，<EmbedInteropTypes>从false更改为true。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3976773|在某种程度上，Visual增加了将COM包装器直接嵌入到程序集中而不是引用PIA的功能，因此我猜想Windows10上的新VS2015安装不再安装PIA，因为它们是不必要的。所以，这就是为什么删除和重新添加引用解决了问题，项目也应该继续在旧操作系统上构建良好。|3976774|entityMap^0|2W|D|3A|7|3K|6|3R|J|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]|$9|Q|A|R|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|S|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|T|8|@]|D|@]|E|$]]]|I|$]]

I had the same issue and I think what's going on, at least in my case, is that the project was originally a VS2012 project on Windows 7 and there was a primary interop assembly installed that was referenced. When I removed and re-added the reference to MSHTML and did a diff on the files, the only difference was that the <code>&lt;WrapperTool&gt;</code> was changed from <code>primary</code> to <code>tlbimp</code> and <code>&lt;EmbedInteropTypes&gt;</code> was changed from false to true.

At some point, Visual Studio added the ability to embed the COM wrappers directly into the assembly instead of referencing PIAs, so my guess is that a new VS2015 installation on Windows 10 no longer installs PIAs because they're not necessary. So that's why removing and re-adding the reference fixes the problem and the project should continue to build fine on older OS as well.

In case if all of the above failed to work for you, here's my solution which is different to the above and it worked for me:

I registered the microsoft.mshtml.dll in the global assembly cache. 

Here is the solution:

Step 1:
Open the Developer Command Prompt by typing dev in your windows 10 search box and right click the Developer Command Prompt for VSxxxx and run as administrator

Step 2:
Navigate to your microsoft.mshtml.dll library.
In my case:

<pre><code>CD C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\PublicAssemblies&gt;
</code></pre>

Step 3
Run the following command to register in the global assembly cache:

<pre><code>gacutil -i Microsoft.mshtml.dll
</code></pre>

MSHTML is still an important component in Windows 10, even with Edge as the default browser. You can find it in "C:\Windows\System32". To quote from the official FAQ:

MSHTML:

<blockquote>
 In Windows 10 the WebBrowser control will use Internet Explorer’s
 legacy rendering engine, mshtml.dll. At this time EdgeHTML is not
 available through the WebBrowser control.
</blockquote>

EdgeHtml

<blockquote>
 In Universal Windows Apps built for Windows 10, the WebView control
 use Microsoft EdgeHTML. WebView controls in apps built for Windows 8 &amp;

For some reason in my case the <code>Microsoft.mshtml</code> file was located in a different directory. On Visual Studio, double click the assembly reference, and you'll find the path to it. Now open the "Developer Command Prompt for VS2017", type the following <code>cd C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\PublicAssemblies</code>. Then <code>regasm Microsoft.mshtml.dll</code>.

Using VS 2015 I had this issue after the last Windows 10 update. I removed the reference "Microsoft HTML Object Library" and added it again to the project. This resolved the issue in my case.

I have a C# solution that makes use of <a href="https://smithhtmleditor.codeplex.com/">Smith Html Editor</a> (I'm developing on the main project which uses this, so I don't know much about this library), which makes a reference to MSHTML. This worked fine until my upgrade to Windows 10 and it can't find MSHTML anymore. I can directly reference the DLL on the GAC folder, and it stops complaining and thus builds, but it's getting some runtime errors related to the editor not instantiating.

After a little research, it turns out that MSHTML is phased out of Windows 10 as it now uses EdgeHTML. Does anyone have any idea how I can go around this? 

The solution still works for Windows 7.

我有一个C#解决方案，它使用 (我正在开发使用的主项目，所以我对这个库不太了解)，它引用了MSHTML。这很好，直到我升级到Windows 10，它再也找不到MSHTML了。我可以直接引用GAC文件夹上的DLL，它停止抱怨并因此构建，但是它得到了一些与编辑器相关的运行时错误，而不是实例化。经过一些研究后，事实证明MSHTML已经逐步淘汰了Windows10，因为它现在使用的是EdgeHTML。有人
