Visual Studio 2019 [Community Edition]: Entity Data Model Wizard crashing when choosing a Data Connection for Oracle Data Source
This is a tricky error when the Entity Data Model crashes right next to the connection properties at below step in Visual Studio 2019 Community Edition.
This is due to unsupported Oracle Data Access Components Nuget package on the version of Visual Studio that you are using.
Below is the information available on Oracle site.
Oracle Developer Tools for Visual Studio is required to enable Visual Studio data features such as Server Explorer integration, TableAdapter Configuration Wizard and Entity Designer. It also adds useful Oracle specific features. Visual Studio 2017 Community Edition is currently not supported with Oracle Developer Tools. We will support it in our next release!
Although it mentions the 2017 Community Edition, but you get the same error on Visual Studio 2019 as well.
