Visual Studio 2013: Database Project MSBuild error

Question

I've got a database project as part of my solution in Visual Studio 2013. Been working perfectly for the last 3 weeks and now suddenly today it won't build and so I cannot publish any changes. I'm getting an MSBuild error:

"C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\SSDT\Microsoft.Data.Tools.Schema.SqlTasks.targets(513,5): Error: MSB4018: The "SqlBuildTask" task failed unexpectedly. System.MethodAccessException: Attempt by method 'Microsoft.Data.Tools.Schema.Sql.Build.SqlTaskHost.OnCreateCustomSchemaData(System.String, System.Collections.Generic.Dictionary`2)' to access method 'Microsoft.Data.Tools.Components.Diagnostics.SqlTracer.ShouldTrace(System.Diagnostics.TraceEventType)' failed."

Anyone got any ideas? All I did this morning was pull down the latest changes from source control. I can't see how that would mess up the actual MSBuild process, and the guy who checked in last doesn't have any issues at all.

Answer 1

You need to install the last version of SQL Server Data Tools:

Make sure to restart VS and then build the solution again. This solves the problem!

Answer 2

In Visual Studio 2013 -> Tools -> Extensions and Updates... -> Updates -> Product Updates -> Microsoft SQL Server Update for database to 12.0.50318.0

I was upgrading from 12.0.41012.0 and this resolved my issue. This relates to the answer to install the latest SQL Server Data Tools.

Answer 3

I am using Visual Studio Community 2013.

I had same error:

You can fix it by updating the SQL Server Tools:

Tools --> Extensions and Updates

Then under Product Updates you will see an option to update SQL Server Update.

Click on Update, after it has installed restart Visual Studio.
