I have a solution in Visual Studio 2013 which contains a SQL Server Database Project and I have recently added a Unit Test Project which has 136 tests in it. In Test Explorer, when I click on Run All to execute all of the tests, I receive the following error:
04018: 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. at Microsoft.Data.Tools.Schema.Sql.Build.SqlTaskHost.OnCreateCustomSchemaData(String filePath, Dictionary`2 referenceMetadata) at Microsoft.Data.Tools.Schema.Sql.Build.SqlTaskHost.CreateCustomSchemaData(String filePath, Dictionary`2 referenceMetadata) at Microsoft.Data.Tools.Schema.Tasks.Sql.TaskHostLoader.ProcessReferences(TaskLoggingHelper providedLogger, SqlTaskHost host, ErrorManager errors) at Microsoft.Data.Tools.Schema.Tasks.Sql.TaskHostLoader.LoadImpl(ITaskHost providedHost, TaskLoggingHelper providedLogger) at Microsoft.Data.Tools.Schema.Tasks.Sql.TaskHostLoader.Load(ITaskHost providedHost, TaskLoggingHelper providedLogger) at Microsoft.Data.Tools.Schema.Tasks.Sql.SqlBuildTask.ExecuteLoadTaskHostStep() at Microsoft.Data.Tools.Schema.Tasks.Sql.SqlBuildTask.ExecuteStep(Func`1 step) at Microsoft.Data.Tools.Schema.Tasks.Sql.SqlBuildTask.Execute() at Microsoft.Build.BackEnd.TaskExecutionHost.Microsoft.Build.BackEnd.ITaskExecutionHost.Execute() at Microsoft.Build.BackEnd.TaskBuilder.d__20.MoveNext()
