This version of Visual Studio is unable to open the following projects.

Question

I am trying to open a SLN file from 2017 0r 2019 Visual Studio. For some reason the source sales.sln file will not open. Solution explorer states that the project is incompatible with the current edition of visual studio, but other team members with the 2017 version are able to open the file. Does anyone have any ideas on why this could be happening? Thanks for any assistance.

Solution

Answer 1

The project types may not be installed

As the message clearly says, the project type isn't installed.

Sales.rptproj

RPTproj = SSRS Reporting Servcies project, so install it from MS MarketPlace/ Visual Studio Extension Manager
