Microsoft.VisualStudio.Component.CoreEditor not found

See original GitHub issue

Hey,

I have compiled latest master and I’m trying to install the ProjectSystem.vsix with a different packageid (+different id for CSharp projects, I removed VB…etc.)

But when trying to install the result vsix from debug folder, I’m getting the following exception from the logs:

 Extension cannot be installed to the following products due to missing prerequisites:
 	Visual Studio Enterprise 2019 Preview
 		-------------------------------------------------------
 		Identifier   : Microsoft.VisualStudio.Component.CoreEditor
 		Name         : Visual Studio core editor
 		Version      : [15.0,16.0)
 		Error        : The prerequisite version specified does not match the version installed

I can’t find anything about this Microsoft.VisualStudio.Component.CoreEditor How can I install it? Why is is not part of my existing VS2019 Preview?

So, this is essentially a VSIX bug. The project system VSIXes are “special” in that they have manifest information that identifies them as “System Components”. If you were to look at the extension.vsixmanifest file inside artifacts\Debug\VSSetup\ProjectSystem.vsix you would see an entry like this:

  <Installation SystemComponent="true" Experimental="true">
    <InstallationTarget Version="[15.0,]" Id="Microsoft.VisualStudio.Pro" />
    <InstallationTarget Version="[15.0,]" Id="Microsoft.VisualStudio.VSWinDesktopExpress" />
    <InstallationTarget Version="[15.0,]" Id="Microsoft.VisualStudio.VWDExpress" />
    <InstallationTarget Version="[15.0,]" Id="Microsoft.VisualStudio.VSWinExpress" />
  </Installation>

SystemComponent="true" means that this isn’t a real vsix but a core VS component that needs to be treated differently by the VS installer. This entry here makes double-click install not work because the default VSIX installer (not the VS installer) doesn’t know how to update core VS components.

Experimental="true" means that this VSIX is allowed to install and override existing VS components (the currently installed project system bits). This is orthogonal to your problem but I thought I would explain for completeness.

I will need to test it, but I believe removing this line will turn ProjectSystem.vsix into a normal vsix. https://github.com/dotnet/project-system/blob/1038ba9e8c0760a9fc7adf89fdc18e339f0c2abd/src/ProjectSystemSetup/ProjectSystemSetup.csproj#L15

@clarkcant look into the file called extension.vsixmanifest in the VSIX file. VSIX file is a simple ZIP file that you can extract the content of it.
