CRM Visual studio project Unsupported error: Project types may not be installed

Case study:

When we download the CRM projects from the GIT or TFS repository with old version like VS 2013/2015 version and try to open in latest version like 2017/2019

Issue replication: Open the downloaded project from GIT repo in VS 2017/2019, then we hit with this error.

Though the migration scripts run behind, to upgrade most of the code to work in latest version, but still we facing below error from migration script

The application which this project type is based on was not found. Please try this link for further information: http://go.microsoft.com/fwlink/?LinkID=299083&projecttype=089D5B2A-9C2F-4B6D-9F7B-CFD25BB0B7F4

Resolution:

Make a copy of the existing project that is corrupted, Just open the .csproj file for the project that is corrupted in any editor like notepad/notepad++ and find the tag <ProjectTypeGuids>. Replace the <ProjectTypeGuids> entire line with below and save.

<ProjectTypeGuids>{349c5851-65df-11da-9384-00065b846f21};{fae04ec0-301f-11d3-bf4b-00c04f79efbc}</ProjectTypeGuids>

Now try to open the project in Visual studio latest version, that should have resolved the issue. Thanks Xrmpedia for sharing
