The type or namespace name 'DataMember' could not be found (are you missing a using directive or an assembly reference?) 


using System.Runtime.Serialization;

        [DataMember]
        public string FileName { get; set; }

Solution:

Add this reference to your project:

System.Runtime.Serialization (System.Runtime.Serialization.dll)

System.Runtime.Serialization

The imported project WebApplication.targets was not found. Confirm that the path in the declaration is correct and that the file exists on disk.

The imported project WebApplication.targets was not found. Confirm that the path in the <Import> declaration is correct and that the file exists on disk.

Quick Solution (not considering MSBuild versions):

Copy the folder with the latest version number from C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio and paste it in C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio and renamed it to the version that is missing. Example:
Copy and paste:
  C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0 
as:
  C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v10.0

Note: In the above solution, "C:\Program Files (x86)\" may be "C:\Program Files\" on your machine.

Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets"

Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets"


The imported project "C:\Program Files *** MSBuild Microsoft VisualStudio *** WebApplicationsMicrosoft.WebApplication.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk. 

Solution:

Switch:

<Import Project="$(MSBuildBinPath)\Microsoft.CSharp.targets" />

to:

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />


or change:

<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />

to:

<Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

If the issue persists then remove the following block from your csproj file:

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

The type or namespace name 'Mvc' does not exist in the namespace 'System.Web'

The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

Solution: 

Clean your solution and then set the property of those references to Copy Local = True. If Copy Local is read-only, remove the reference and add it to the project again.

 

Copy Local = True
