I am working on Visual Studio 19 Pro and have been unable to open any of my Tabular model projects. I have checked that extensions are installed have rolled back the versions and uninstalled/reinstalled and I continue to get the following:
Error Cannot build obj\Development\Model.asdatabase. Reason: Method not found: 'Microsoft.AnalysisServices.Database Microsoft.AnalysisServices.JsonSerializer.DeserializeDatabase(System.String, Microsoft.AnalysisServices.Tabular.DeserializeOptions, Microsoft.AnalysisServices.CompatibilityMode)'.
Method not found: 'Microsoft.AnalysisServices.Tabular.Model
I am on VS19 Version 16.8.4
Microsoft Analysis Services Project V 2.9.14
I am able to open SSIS projects and SSRS project with no issue.
