When I try to install my VSIX to VS 15 Preview 5 I get the warning
"This extension is not compatible with Visual Studio 15 and will not be supported in RC":
Microsoft blog does not provide any notes about this issue.
This should be related to a new VSIX manifest format, which is JSON instead of XML, but I can not find any info regarding upgrade process of the manifest.
How to upgrade my manifest to resolve this issue?
You can download upgrade documentation to VSIXv3 from this link.
Mostly you should use VS "15" and add <GenerateVsixV3>true</GenerateVsixV3>
to your project file. That will add manifest.json
to your new vsix.
