Home: nuget configuration is invalid - VS 2015 VSIX (v3.4.3)

[jhngrant]

No joy after trying most suggested fixes listed here: http://stackoverflow.com/questions/32344232/unable-to-install-any-package-in-visual-studio-2015

Only solution was to fallback to VS 2015 VSIX (v3.4.2)

Seems to occur when a website project is running in IIS rather that IIS Express ?

[rrelyea]

Thanks for the report.
Please tell us detailed steps on how we can reproduce the problems?

[jhngrant]

Are there any error log files I can send you?

[rrelyea]

My guess is that you have a nuget.config that is invalid XML, which used to be silently ignored.
In 3.4.0 we changed that to error: https://github.com/NuGet/Home/issues/1567

[yishaigalatzer]

Our fix went in 3.4 and this complaint is about 3.4.2 vs 3.4.3 so I'm guessing something else is going on. Can you share the nuget.config files and error logs?

[jhngrant]

I've reinstalled 3.4.3.855. I have a number of projects in a VS solution. When I pick 'Manage NuGet Packages...' on a C# class library NuGet opens as expected. When I try the same command on a Website project hosted in IIS I get the 'nuget configuration is invalid' error alert.

In Tools > NuGet Package Manager > Package Manager Console: All the projects with the error don't appear in the 'Default project' dropdown.

There is no entries relating to NuGet in the VS activity log: %APPDATA%\Microsoft\VisualStudio\Version\ActivityLog.xml

Googled the location of the NuGet error log but can't find it. Can anyone suggest its location?

I've attached: %APPDATA%\NuGet\NuGet.Config

NuGet.zip

@jhngrant what type of project are you using, a web site, web application, something else? Is there an msbuild project file for this project?

Does the project contain a project.json file or packages.config file?

[zhili1208]

@emgarten I think this is also https://github.com/NuGet/Home/issues/2601, for some reason, website nugetProject initialization fails.

[yishaigalatzer]

Can you compare to 2.8.x ?

@emgarten Web site project

@emgarten Attached is the packages.config of a Web site project with the 'nuget configuration is invalid' error:
packages.zip

There is no project.json

To create this type of project File > New > Web Site...

I made the issue replicate. I started my project in VS 2012 then later migrated to 2015. The .sln file looks as follows:

Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio 14
VisualStudioVersion = 14.0.25123.0
MinimumVisualStudioVersion = 10.0.40219.1
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "ClassLibrary3", "ClassLibrary3\ClassLibrary3.csproj", "{861BE5F0-9725-4BE1-82A1-6C3AAD478D4B}"
EndProject
Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "testSite", "http://localhost:63775", "{348EB0EA-8C3F-45CB-A248-BBC2616AAFE4}"
    ProjectSection(WebsiteProperties) = preProject
        UseIISExpress = "true"
        TargetFrameworkMoniker = ".NETFramework,Version%3Dv4.0"
        ProjectReferences = "{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}|ClassLibrary3.dll;"
        Debug.AspNetCompiler.VirtualPath = "/localhost_63775"
        Debug.AspNetCompiler.PhysicalPath = "testSite\"
        Debug.AspNetCompiler.TargetPath = "PrecompiledWeb\localhost_63775\"
        Debug.AspNetCompiler.Updateable = "true"
        Debug.AspNetCompiler.ForceOverwrite = "true"
        Debug.AspNetCompiler.FixedNames = "false"

        Release.AspNetCompiler.TargetPath = "PrecompiledWeb\localhost_63775\"
        Release.AspNetCompiler.Updateable = "true"
        Release.AspNetCompiler.ForceOverwrite = "true"
        Release.AspNetCompiler.FixedNames = "false"
        Release.AspNetCompiler.Debug = "False"
        SlnRelativePath = "testSite\"
        DefaultWebSiteLanguage = "Visual C#"
    EndProjectSection
EndProject
Global
    GlobalSection(SolutionConfigurationPlatforms) = preSolution
        Debug|Any CPU = Debug|Any CPU
        Release|Any CPU = Release|Any CPU
    EndGlobalSection
    GlobalSection(ProjectConfigurationPlatforms) = postSolution
        {861BE5F0-9725-4BE1-82A1-6C3AAD478D4B}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
        {861BE5F0-9725-4BE1-82A1-6C3AAD478D4B}.Debug|Any CPU.Build.0 = Debug|Any CPU
        {861BE5F0-9725-4BE1-82A1-6C3AAD478D4B}.Release|Any CPU.ActiveCfg = Release|Any CPU
        {861BE5F0-9725-4BE1-82A1-6C3AAD478D4B}.Release|Any CPU.Build.0 = Release|Any CPU
        {348EB0EA-8C3F-45CB-A248-BBC2616AAFE4}.Debug|Any CPU.ActiveCfg = Debug|Any CPU
        {348EB0EA-8C3F-45CB-A248-BBC2616AAFE4}.Debug|Any CPU.Build.0 = Debug|Any CPU

        {348EB0EA-8C3F-45CB-A248-BBC2616AAFE4}.Release|Any CPU.Build.0 = Debug|Any CPU
    EndGlobalSection
    GlobalSection(SolutionProperties) = preSolution
        HideSolutionNode = FALSE
    EndGlobalSection
EndGlobal

If I change the second Project line to read, Project("{E24C65DC-7377-472B-9ABA-BC803B73C61A}") = "testSite", "testSite\", "{348EB0EA-8C3F-45CB-A248-BBC2616AAFE4}", the problem goes away. Note that sln files generated by VS2015 look like this.

Downgrading to 3.4.2 also solves the issue for me.

[rrelyea]

Can you please try:
1) download not yet final version 3.4.4. of the vsix:
https://www.myget.org/F/nuget-vsix/vsix/NuGet.0d421874-a3b2-4f67-b53a-ecfce878063b-3.4.4.870.vsix

2) close VS 2015.
3) double click the new vsix to install.
4) launch VS.
5) try out your project.
6) tell us how it went

[jhngrant]

@rrelyea 3.4.4 has fixed the 'nuget configuration is invalid' issue on the web site projects. Also OK on other projects types I work on.

[ardentra]

@rrelyea we just ran into this same issue for our website projects. Installing this new vsix fixed the issue for usas well.
