MSBuild referencing assemblies with wrong target Framework version? (warning MSB3275 / warning MSB3268)

Question

Hello everyone,

I'm not exactly sure if my problem is related to MSBuild, but I'm hoping to find find someone that can enlighten me on this.
(I've already asked this question in the SQL Server Reporting Services Forum, but it seems like my issue is not directly related to SSRS)

I installed the ReportViewer 14 NuGet package in a Windows Forms Application targeting .NET Framwork 4.0.

When building, I'm receiving several warnings similar to the following:

warning MSB3275: The primary reference "Microsoft.ReportViewer.Design, Version=14.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91, processorArchitecture=MSIL" could not be resolved because it has an indirect dependency on the assembly "Microsoft.VisualStudio.Shell.14.0, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0".

The application builds successfully and everything seems to work, but I'm a still little concerned about the warnings.

However, my coworkers are not seeing these warnings, and the only obvious difference I could tell is that they are using Windows 10 and I'm on Windows 7. Maybe it also has something to do with prior Visual Studio Versions I have/had installed?

Here is the complete output for your reference:

Answer 1

Hi powerzone3000,

Thanks for posting here.

>>>MSBuild referencing assemblies with wrong target Framework version? (warning MSB3275 / warning MSB3268)

I`m afraid the workaround current is to upgrade the target framework to .NET 4.5 and above.

I installed that package on Windows 7 & 10 with .NET framework 4.0, then built the project, both got the same warnings as you. According to the error log, "because it has an indirect dependency on the assembly "Microsoft.VisualStudio.Shell.14.0“ which was built against the ".NETFramework,Version=v4.5" framework.", So I changed the target framework to 4.5, those warnings are disappear.

But you said: "Your coworkers are not seeing these warnings on windows 10", you should double check the target framework of your coworker's projects.

Answer 2

Hi Leo-Liu,

thanks for your reply, I'm glad that you can confirm this behaviour.

I also noticed that the Microsoft.ReportViewer.Design.dll is missing in the output directory after the build process.

I just double-checked at one of my coworkers PC's, and they are in fact building against Target framework 4.0.
It even happens with the exact same project: Builds fine on my coworkers machine, but produces warnings on my machine.

So I suspect it has something to do with something that is, respectively is not installed on the particular machine.

Answer 3

>>>So I suspect it has something to do with something that is, respectively is not installed on the particular machine.

Thanks for your reply. Did your coworkers PC's have to install .net4.5? According to error "Microsoft.VisualStudio.Shell.14.0 which was built against the ".NETFramework,Version=v4.5" framework. This is a higher version than the currently targeted framework ".NETFramework,Version=v4.0"， that means those  eference dll were updated by .NET framework update. 

Apparently if you have only .NET Frameworks 4.0 installed, you can add as a reference a .NET assembly that targets 4.5 to a project that targets .NET 4.0. This will compile and run with no errors.

As soon as you install .NET Frameworks 4.5, compile will fail. The solution is to target your project for .NET Framework 4.5 or get a version of the referenced assembly that targets .NET 4.0.

.NET 4.5 is a drop in replacement for 4.0. 4.0 doesn't know anything about 4.5, and I assume it is just looking at the first digit of the version number which for 4.0 or 4.5 is the same, so it is allowed to compile. As soon as you install 4.5, your 4.0 projects are compiled using the 4.5 Frameworks and it now knows about 4.5 and complains.

So resolve this warning, you need update your target framework to 4.5 or scroll down the framework to 4.0 (not easy to do this.)

Answer 4

Hi,

I was finally able to resolve it:

Short answer: The core problem seemed to be the installation of Visual Studio 2015 respectively SQL Server Management Studio 17: after I uninstalled all components of them, the warnings were gone!

Long answer:
The first thing I noticed was, that the assemblies MSBuild complained about (e.g. Microsoft.VisualStudio.Shell.14.0) were installed in my Global Assembly Cache (GAC) whereas they weren't on my colleagues PC's. I verified that by running the following in the Developer Command Prompt:

gacutil /l Microsoft.VisualStudio.Shell.14.0

So something must have had installed these assemblies in the GAC.

The version number "14" pointed in the direction of Visual Studio 2015 (because its internal version number is Visual Studio v14). So I uninstalled everything that had "Visual Studio 2015" in its name - including Visual Studio 2015 Shell (isolated) and SQL Server Management Studio 17.2 (because I knew that SSMS is basically a Visual Studio extension and is installing the "Shell"-Version of VS alongside)

This resolved all of the warnings.

As a "proof of concept", I reinstalled SQL Server Management Studio 17.2 and: The warnings returned.
(after uninstalling it one more time, they were gone again)

This is not a completely satisfying solution though, because I can't install SSMS anymore. Do you think I should report this behaviour to Microsoft? If so, where would be the best place to do so?
