I can not Install AnkhSVN -Subversion Support for Visual Studio 2019,
I have tried to Install It, It says Version is Invalid for VS2019
I use VS2019 Professional
The latest AnkhSVN version is not compatible with Visual Studio 2019 (and the project, unfortunately, seems dead).
A possible solution is to edit manually the files stored in the vsix file (it's a zip file with a different extension).
The file to edit are:
extension.vsixmanifest
Change the occurance of [15.0,16.0) to [15.0,17.0)
Change the prerequisite in this way:
catalog.json
search Microsoft.VisualStudio.Component.CoreEditor and change the version to "[15.0,)"
manifest.json
search Microsoft.VisualStudio.Component.CoreEditor and change the version to "[15.0,)" as the catalog.json
After these changes it's possible to install the extension in VS2019 but still open a warning shown by VS related an incompatibility of the load process (AnkhSVN use a synchronous load, VS2019 want an async load).
