I got this error today when trying to open a Visual Studio 2008 project in Visual Studio 2005:

The imported project \"C:\\Microsoft.C

Answer 1

ok so what if it say this: between the gt/lt signs

Import Project="$(MSBuildExtensionsPath)\Microsoft\Silverlight\v3.0\Microsoft.Silverlight.CSharp.targets" /

how do i fix the targets error?

I also found that import string in a demo project (specifically "Build your own MVVM Framework" by Rob Eisenburg).

If you replace that import with the one suggested by lomaxx VS2010 RTM reports that you need to install this.

This error can also occur when opening a Silverlight project that was built in SL 4, while you have SL 5 installed.

Here is an example error message: The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found.

Note the v4.0.

To resolve, edit the project and find:

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>

And change it to v5.0.

Then reload project and it will open (unless you do not have SL 5 installed).

Answer 3

If you are to encounter the error that says Microsoft.CSharp.Core.targets not found, these are the steps I took to correct mine:

1. Open any previous working projects folder and navigate to the link showed in the error, that is Projects/(working project name)/packages/Microsoft.Net.Compilers.1.3.2/tools/ and search for Microsoft.CSharp.Core.targets file.

2. Copy this file and put it in the non-working project tools folder (that is, navigating to the tools folder in the non-working project as shown above)

3. Now close your project (if it was open) and reopen it.

It should be working now.

Also, to make sure everything is working properly in your now open Visual Studio Project, Go to Tools > NuGetPackage Manager > Manage NuGet Packages For Solution. Here, you might find an error that says, CodeAnalysis.dll is being used by another application.

Again, go to the tools folder, find the specified file and delete it. Come back to Manage NuGet Packages For Solution. You will find a link that will ask you to Reload, click it and everything gets re-installed.

Your project should be working properly now.

Answer 4

Open your csproj file in notepad (or notepad++) Find the line:

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

and change it to

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