Hi All,

I recently updated my VS 2022 to v17.7.0. It seems that breaks the X# integration. The message I got is attached. I tried restarting and that did not help. It looks like it stops you loading any X# project.Here are the relevant entries I can find in that ActivityLog they mentioned.   <entry>    <record>222</record>    <time>2023/08/10 00:30:03.374</time>    <type>Error</type>    <source>Microsoft.VisualStudio.ComponentModelHost.VsShellComponentModelHost</source>    <description>Still unable to load MEF component DLL: Could not load file or assembly 'Microsoft.Windows.Design.Host, Version=4.3.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

I may need to back out that update to VS.

Hi All,

I rolled back VS to v17.6.5 and that seemed to go OK.
When I opened my solution again it seemed to have a problem authenticating my VS Professional subscription. After waiting a while I tried restarting my machine.
It then did not have problem with my subscription but all the X# projects were marked as incompatible.
I uninstalled and reinstalled XSharp v2.16.0.5.
Opening my solution again and all the X# projects were marked as unloaded, so I individually reloaded them, including a few I had deliberately unloaded!
After tidying that up, my solution now builds cleanly, including X# projects.

In case this helps anyone,
John

Hello John,
I updated my VS 2022 to version 17.7 yesterday morning. Also I am using X# 2.17.0.3. So far I have not found any problems in this bundle. Everything works fine.

John,
There was a breaking change in VS 17.7.
X# 2.17.0.3 should work OK with VS 17.7.
Older versions will not work.
If you have to work with this combination, then you can work around this by copying the file Microsoft.Windows.Design.Host.dll from an older installation of VS (in PrivateAssemblies folder) into VS 17.7 which does not have that file anymore.
