This is a quick tip to help quickly solve a problem I run into sometimes, and now that I am writing a blog about it, will be able to solve it in no time (a big benefit of blogging is to never have to try to remember a solution to a problem you have had before…just search your blog!):
In Visual Studio, I have a solution that encompasses three projects: a SSIS project, a SSAS project, and a SSRS project. Say I’m working on the SSAS project in this solution and it’s in an incomplete state. Then I get an email that there is a problem with a SSIS package, and that package is in the same solution under the SSIS project. So I go to that package and hit debug, and the SSIS package does not run because it tried to deploy the SSAS project and there were errors. Why does it try to deploy the SSAS project when I’m just trying to run a SSIS package?
The problem is your solution is set up to build and/or deploy ALL the projects when you just want to debug one project. The solution is simple - right click the solution, select “Configuration Manager…”, and uncheck the “Build” and “Deploy” boxes:
Now, when you debug the SSIS package, the SSAS project and any other packages will be ignored.
