I have solution with 2 projects both targeting .Net Framework 4. The solution builds successfully in Visual Studio 2015 and 2017 as well as the msbuild command line.
However, when it builds in Azure DevOps Pipeline with Agent Specification vs2015-win2012r2 the first project fails with the following errors. The NuGet restore step shows it successfully installed the NuGet EntityFramework 5.0 package.
The type or namespace name 'Infrastructure' does not exist in the namespace 'System.Data.Entity' (are you missing an assembly reference?)
The type or namespace name 'DbContext' could not be found (are you missing a using directive or an assembly reference?)
The type or namespace name 'DbModelBuilder' could not be found (are you missing a using directive or an assembly reference?)
When I change the Agent Specification to vs2017-win2016 the first project builds without error but the second project fails with the following errors:
The type or namespace name 'Description' does not exist in the namespace 'System.Web.Http' (are you missing an assembly reference?)
The type or namespace name 'Http' does not exist in the namespace 'System.Net' (are you missing an assembly reference?)
Error CS0234: The type or namespace name 'Http' does not exist in the namespace 'System.Net' (are you missing an assembly reference?)
I do have the NuGet package Microsoft.Asp.Net.WebApi.Core.4.0.20710.0 referenced in the csproj file which contains the System.Web.Http.dll.
I have turned the debug option on. Here are links to the NuGet Restore Log https://drive.google.com/open?id=1lJWflXTjYTN_MQyLOnwMUr-8LKoR5JRo
and the Build Log

According to your log, there is a warning message.
warning MSB3267: The primary reference "System.Net.Http", which is a framework assembly, could not be resolved in the currently targeted framework. ".NETFramework,Version=v4.0". To resolve this problem, either remove the reference "System.Net.Http" or retarget your application to a framework version which contains "System.Net.Http".
Some differences are in effect when executing a command on a local machine and when a build or release is running on an agent. If the agent is configured to run as a service on Linux, macOS, or Windows, then it is not running within an interactive logged-on session. Without an interactive logged-on session, UI interaction and other limitations exist. And there are some troubleshooting steps which was provided by Microsoft.
There is a simple method that you can try to resolve the error. Delete the reference under the project's references, and then juse add it back in again.The reference was to a namespace in a local project to the solution. For some reason it was being found locally but not found when checked into and built on VSTS.

Am using VS 2017 Enterprise edition and doing Xamarin Mac.
We are a licensed user of ServiceStack and I am using the latest version. I've created an LLBLGen project and added the latest ServiceStack LLBLGen templates. I am able to generate the LLBLGen projects, but the XXXXProject.Services class library fails to compile:
Error 1 The type or namespace name 'ServiceHost' does not exist in the namespace 'ServiceStack' (are you missing an assembly reference?) C:\PROJECTS\ServiceStack\XXXXService\XXXXService.ServiceModel\DAL\ServiceGeneric\Validators\VendorValidator.cs
Are the templates compatible with ServiceStack v4? If not, do you know when they will be compatible or what I need to change to make them work with the latest version of ServiceStack?
Thanks,
Mike
I build my application and run it in debug mode. Everything is ok. I can test the functionality and everything is working. Its a multi tier MVC application using Entity Framework 6.0.
Now, when I change the build from Debug to Release and build the projects. I get a few hundreds build errors. All the errors are in the Data Access layer where I use the Entity Framework 6.0. The errors are in the form of:
Error 388 The type or namespace name 'DbSet' could not be found (are you missing a using directive or an assembly reference?)
Or
Error 201 The type or namespace name 'Schema' does not exist in the namespace 'System.ComponentModel.DataAnnotations' (are you missing an assembly reference?)
I have tried cleaning the solution and rebuilding but always same. Not sure why this can happen? Any suggestion will be appreciated.
many thanks
