The target "MSDeployPublish" does not exist in the project

Adding the lines below to my .csproj file seems to solve the same error for me:

<PropertyGroup>
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
<VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
</PropertyGroup>

As part of trying to resolve the issue, I've also installed the MSBuild.Microsoft.VisualStudio.Web.targets Nuget Package. But I'm still not sure it was necessary in order to resolve the issue.

If you get this MSB4057 error from a WebJob project using "Publish as Azure WebJob" using Visual Studio 2013/update 4 - you may need to update the NuGet package Microsoft.Web.WebJobs.Publish

Check MyWebJob\packages.config and if the version is 1.0 you need version 1.02 or higher. From the package manager console run

 Install-Package Microsoft.Web.WebJobs.Publish -Version 1.0.2

With VS 2013 Update 4. There seems to be issues with the template of a Webjob project so that the reference to webjobs.targets is wrong, even though you've installed the Microsoft.Web.WebJobs.Publish package.

Make sure There Import statement at the bottom of of the project is correct in terms of the path, I tested twice and found it was malformed.

<Import Project="..\..\packages\Microsoft.Web.WebJobs.Publish.1.0.2\tools\webjobs.targets" Condition="Exists('..\..\packages\Microsoft.Web.WebJobs.Publish.1.0.2\tools\webjobs.targets')" /> 

Also, better avoid using the below, since it binds you to a specific VS version.

<PropertyGroup>
<VisualStudioVersion Condition="'$(VisualStudioVersion)' == ''">10.0</VisualStudioVersion>
<VSToolsPath Condition="'$(VSToolsPath)' == ''">$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)</VSToolsPath>
</PropertyGroup>
