How to add SQL Server Project to Azure Devops Services

Hi all ,

I need help in adding SQL Server Project(consists T-SQL scripts only) to Azure repos(I am very new to Version control system). So far I could manage to add SSIS/SSRS/SSAS projects to my master solution on Azure Repos. But not much luck with SQL Server Project.

I am not sure if we have any extensions? with out using redgate version control or Database project.

Currently we are using 

SQL Server  Management Studio  v17.81

Visual Studio 2017(SSDT)

Github for Azure repos

Thanks in advance
