vsixmanifest for all: VS 2010, 2012 and 2013

Question

I'm using VSIX Manifest Designer under VS2013. I've added Microsoft.VisualStudio.Pro product identifier and [10.0,13.0) version range to install targets. Despite that fact, I still don't see my VS2010 Professional as an available installation target:

The source.extension.vsixmanifest file content is shown below:

<?xml version="1.0" encoding="utf-8"?> <PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">   <Metadata>     <Identity Id="ae98c9e5-8e14-4c92-b45a-c4fd24a49123" Version="1.0" Language="en-US" Publisher="whosoever" />     <DisplayName>MyExtension</DisplayName>     <Description xml:space="preserve">whosoever</Description>     <MoreInfo>http://www.myextension.com</MoreInfo>     <License>LICENSE.txt</License>     <Icon>icon.png</Icon>     <PreviewImage>screenshot.png</PreviewImage>   </Metadata>   <Installation InstalledByMsi="false">     <InstallationTarget Version="[10.0,13.0)" Id="Microsoft.VisualStudio.Pro" />   </Installation>   <Dependencies>     <Dependency Id="Microsoft.Framework.NDP" DisplayName="Microsoft .NET Framework" d:Source="Manual" Version="4.5" />     <Dependency Id="Microsoft.VisualStudio.MPF.11.0" DisplayName="Visual Studio MPF 11.0" d:Source="Installed" Version="11.0" />   </Dependencies>   <Assets>     <Asset Type="Microsoft.VisualStudio.VsPackage" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%;PkgdefProjectOutputGroup|" />   </Assets> </PackageManifest> 

What should be changed to enable installation of this extension to VS2010, 2012 and 2013?

Answer 1

What you have is the version 2 VSIX manifest, which is not compatible with Visual Studio 2010. Later Visual Studio versions respect version 1 of the manifest, so in order to support all 3 Visual Studio versions with a single manifest, you'll have to convert it to v1.0 manually (and make sure NOT to edit it with VS2012+, otherwise it will be converted back to v2.0).

Something like this:

<?xml version="1.0" encoding="utf-8"?> <Vsix xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="1.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010">   <Identifier Id="ae98c9e5-8e14-4c92-b45a-c4fd24a49123">     <Name>MyExtension</Name>     <Author>whosoever</Author>     <Version>1.0</Version>     <Description xml:space="preserve">Your decription.</Description>     <Locale>1033</Locale>     <SupportedProducts>       <VisualStudio Version="10.0">         <Edition>Pro</Edition>       </VisualStudio>       <VisualStudio Version="11.0">         <Edition>Pro</Edition>       </VisualStudio>       <VisualStudio Version="12.0">         <Edition>Pro</Edition>       </VisualStudio>     </SupportedProducts>     <SupportedFrameworkRuntimeEdition MinVersion="4.0" />   </Identifier>   <Content>     <VsPackage>|%CurrentProject%;PkgdefProjectOutputGroup|</VsPackage>     <MefComponent>|%CurrentProject%|</MefComponent>   </Content> </Vsix> 

You don't have to specify all product editions (called SKUs), Pro is enough, if, say, Ultimate is installed, it will be displayed instead.
