Visual Studio LightSwitch will not Build - c#

I'm working with an old C# LightSwitch HTML project that connects to SharePoint and I need to make a few changes. Unfortunately not enough to justify migrating to another technology/platform, but anyways...
I fire up my Visual Studio 2015 and the project won't build. I've of course googled for and tried everything I can think of and long story short even if I create a new C# LightSwitch HTML project and try to build it, it fails. Here's the error I get:
An exception occurred when building the database for the application.
An error occurred during deployment plan generation. Deployment cannot continue.
Error SQL0: Required contributor with id 'Microsoft.LightSwitch.DataRetentionDeploymentPlanModifier.v5.0' could not be loaded.
Error SQL0: Required contributor with id 'Microsoft.LightSwitch.LocalDbLocationModifier.v5.0' could not be loaded. GraphicsApp C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\LightSwitch\v5.0\Microsoft.LightSwitch.targets 160
If I go to line 160 (double-clicking on the error) I see this (Starting at line 160):
<BuildSchema Inputs="#(ServerMetadataFiles)"
ServerGeneratedMetadataFiles="#(ServerGeneratedMetadataFiles)"
Collation="$(DatabaseCollation)"
DatabaseProject="#(_DatabaseProject)"
ProjectPath="$(MSBuildProjectFullPath)"
OutputDirectory="Bin\Data"
SqlExpressInstanceName="$(SqlExpressInstanceName)"
ExternalDataSources="#(ServerExternalDataSources)"
Condition="'$(SkipBuildSchema)' == ''"/>
I've tried searching everything I can think of but I'm not finding anything that even sounds remotely the same except this link. But it's talking about V4 and only says that the solution was to:
"right clicking on the project in solution explorer... [and] upgrade
the project"
But that doesn't help me at all because I don't see any option to upgrade anything and again I have the same exact problem on the brand new project I create.

Do you know what version of SQL Server Data Tools (SSDT) you have installed?
The latest update 14.0.61707.300 breaks LightSwitch with that error.
You could try uninstalling SSDT and installing the previous version.

Had same issue...

SSDT version 17.4 (14.0.61712.050) https://go.microsoft.com/fwlink/?linkid=863440
breaks our SSRS,
as does SSDT version 17.3 (14.0.61709.290)

Breaks our LightSwich.

By Trail and Error, found SSDT for VS2015 17.2 Works For both LightSwitch and SSRS
https://go.microsoft.com/fwlink/?linkid=852922

For a Windows 10 machine, with previously installed Visual Studio 2017, the installation of Visual Studio 2015 and running the Lightswitch project, nothing worked, but this:
copy all the content from this location "C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\130\Extensions"
to
"C:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\IDE\Extensions\Microsoft\SQLDB\DAC\140\Extensions"
Found that solution on MSDN.

I just faced a similar situation here, but I could not find a version 13.x of SSDT and upgrading to the oldest version available in the Microsoft website didn't help.
The error was fixed when I decided to do some VS pending updates, on of them being the Office Developer Tools for VS, which was updated to

The imported project C:\...\v4.5\Microsoft.Expression.Blend.WPF.targets" was not found

I was developing my WPF projects using Visual Studio 2013 in my old window 7. But when I installed new Windows 10 and also Visual Studio 2017 and tried to open my project; my project fail to load and got this error message:
the imported project "C:\Program Files (x86)\Microsoft Visual
Studio\2017\Enterprise\MSBuild\Microsoft\Expression\Blend.NETFramework\v4.5\Microsoft.Expression.Blend.WPF.targets"
was not found. Also, tried to fiend

I Searched for some solutions I found I have to install BlendWPFSDKv4_en.msi Version 4, but still doesn't help also there is no BlendWPFSDKv4_en.msi version 4.5. What Should I do, Shall I install VS 2013 in order to fix this issue?
The imported project C:\…\v4.5\Microsoft.Expression.Blend.WPF.targets" was not found
Found it. You should launch the Visual Studio Installer from the start menu, switch to the "Individual components" page, under the "SDKs, libraries, and frameworks" heading, find the "Blend for Visual Studio SDK for .NET" and install it:
After the installation is complete, you will find it under the path:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\MSBuild\Microsoft\Expression\Blend.NETFramework\v4.5
Certified:Visual Studio 2017 - What happened to Expression interactions?
Hope this helps.
You can remove the reference to blend;
With VS 2019 - Right click on the (unloaded/load failed) project.
Select - edit your *****.csproj file.
At the bottom of the file, remove the following line
<Import Project="$(MSBuildExtensionsPath)\Microsoft\Expression\Blend\.NETFramework\v4.5\Microsoft.Expression.Blend.WPF.targets" />
Save, Reload the project & happiness.
I had solved the problem by installing
Install Microsoft Expression Blend Software Development Kit (SDK) for .NET 4,
without install an older version of VS
I had solved the problem by installing VS2015 in the same machine that has VS2017 and now the project works fine in VS2017.

Visual Studio stopped supporting my projects

I have Visual Studio 2013 Ultimate. Today when I opened it, it didn't load any of my solution's projects. Error message:
Unsupported
This version of Visual Studio is unable to open the following projects. The project types may not be installed or this version of Visual Studio may not support them.
For more information on enabling these project types or otherwise migrating your assets, please see the details in the "Migration Report" displayed after clicking OK.
- ETL_<Project name>, "<Project path></Project>.csproj"
Non-functional changes required
Visual Studio will automatically make non-functional changes to the following projects in order to enable them to open in Visual Studio 2013, Visual Studio 2012, and Visual Studio 2010 SP1. Project behavior will not be impacted.
- <Project name></Project>, "<Project path></Project>.sln"
These projects are of types Class Library and Console Application. If I try to create a new project, these types are listed, but when I create it I get message <Project path> cannot be opened because its project type (.csproj is not supported by this version of the application. To open it, please use a version that supports this type of project..
So, Visual Studio is telling me it doesn't support a project it just created?! GJ M$!!
Unfortunately I was unable to solve this. I ended up uninstalling VS Ultimate. Now I use VS Express for Desktop, and it works with my old projects.
My assumption is that something on Windows broke some part of VS. I should have tried to uninstall and reinstall it but didn't have the opportunity.
I have the same thing in a Hyper-V VM. After repair did not work, I deinstalled and reinstalled VS 2017. Same thing.
In the host I can still open the same project with VS, so it is not the project, but the VS install that has a problem.
It puts this in the migration log:
src\DTOWEB\project.json: Failed to migrate XProj project DTOWEB. Could not find project.json at C:\DTOWeb\DTOWEB7\src\DTOWEB\project.json.
I have a second VM that is x86 iso x64, and it can open the project without problems. So again, my conclusion is there is nothing wrong with the project.

No templates in Visual Studio 2017

After a Visual Studio 2017 (RC) installation from scratch, I can't find a standard list of templates. I'm specifically interested in the Console Application (C#) template and the Windows Form (C#) template. I'm pretty sure I'm missing one of the Individual Components. I'm not sure which one is supposed to be installed and I don't want to install all of them.
Please see my list with components installed.
You need to install it by launching the installer.
Click the "Workload" tab* in the upper-left, then check top right ".NET-Desktop Development" and hit install. Note it may modify your installation size (bottom-right), and you can install other Workloads, but you must install ".NET-Desktop Development" at least.
*as seen in comments below, users were not able to achieve the equivalent using the "Individual Components" tab.
If you have installed .NET desktop development and still you can't see the templates, then VS is probably getting the templates from your custom templates folder and not installed.
To fix that, copy the installed templates folder to custom.
This is your "installed" folder
C:\Program Files (x86)\Microsoft Visual Studio
14.0\Common7\IDE\ProjectTemplates
This is your "custom" folder
C:\Users[your username]\Documents\Visual
Studio\2017\Templates\ProjectTemplates
Typically this happens when you are at the office and you are running VS as an administrator and visual studio is confused how to merge both of them and if you notice they don't have the same folder structure and folder names.. One is CSHARP and the other C#....
I didn't have the same problem when I installed VS 2017 community edition at home though. This happened when I installed visual studio 2017 "enterprise" edition.
I found the path and wrote it in the options
My personal experience was that I had installed the Team Foundation Server client for 2017 first (was using it as a Proof of Concept for our QA team, while I was still using VS2015), then followed it up with Installing Visual Studio 2017 later to begin development.
What I ended up with on my Start Menu was a Visual Studio 2017 and a Visual Studio 2017 (2). The Visual Studio 2017 (2) had all the templates I was missing. Following the steps found in the First answer to this question (which were clear and easy to follow) did not fix my issue. I had thought that launching the client would upgrade to the Development Client, but it did not. I renamed it to Visual Studio Professional, and now have everything I need. Not sure if this happens to anyone else, but it was what happened to me, so I hope this helps someone.
NOTE: this topic is about installation issues with MS project templates.
I came here via a search in Google, I was looking for a missing Template option in Visual Studio 2017 File menu: in VS-2015, it was Export to Template and I used it to add my own standard Project Items.
Meanwhile, I found an answer.. my issue was not related to default templates and it does not need install things. The option Export to Template has been moved to the VS-2017 Project menu !
I had to reinstall .NET desktop development (throught Workload tab), even button was showing: Modify
After that Visual C# selection appeared :)
(And now i can use Console APP Template)
In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.
When running the Team Explorer version, only the Blank Solution option was available.
The Team Explorer EXE was located in:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"
Once I launched the correct EXE, Visual Studio started working as expected.
The Professional EXE was located in:
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"
My C++ templates were there all along, it was my C# ones that were missing.
Similar to CSharpie, after trying many modify/re-installs, oddly the following finally worked for me :
- run the installer, but un-select 'Desktop development with C++'.
- allow installer to complete
- run the installer again, and select 'Desktop development with C++'.
- allow installer to complete
In my case, I had all of the required features, but I had installed the Team Explorer version (accidentally used the wrong installer) before installing Professional.
When running the Team Explorer version, only the Blank Solution option was available.
The Team Explorer EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\TeamExplorer\Common7\IDE\devenv.exe"
Once I launched the correct EXE, Visual Studio started working as expected.
The Professional EXE was located in: "C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE\devenv.exe"
This solved my issue, and the reason was I had enterprise edition previously installed and then uninstalled and installed the professional edition. Team Explorer was not modified later when I moved to professional from enterprise edition.

This project(Visual Studio 2012 express) is incompatible with the current version of Visual Studio 2013 express

Am doing a back end project in C# in Visual Studio. My team mate had done it using Visual Studio 2012 express and everything seems to work there. But when i used git to clone it to my system where am using Visual Studio 2013 express, one part of the project says its incompatible with the current version of VS. I could clean and build the project, but was unable to run the project. I searched and found that one solution is to go to Programs and features, select VS, right click,select repair. But even after doing this, the problem persists. Is there any work around?
When I was learning ASP.NET MVC by Informit tutorials I was in the very similar situation. I downloaded the sample sources that was created in VS2013 but had VS2015 installed. It was some kind of bug \ magic, but VS didn't recognized some libraries in VS2015 even they were installed. What is more strange is the fact that when I decided to totally rewrite the project line by line it worked!
Of course, I tried to clean, rebuild, reinstall NuGet packages.
So, if you have an access to sources *.cs, then just try to create new project and copy-paste code.

How to fix "You must upgrade the project to target Microsoft Azure Tools 2.8"?

I've got a project that's set to Azure 2.6. I have Visual Studio 2015 installed. I get prompted to upgrade the project (see image 1 below), which I do not want to do (it's production code and I don't know what the side effects may be, how many things might break).
I tried installing Azure 2.6 and related tools, but it doesn't help. Image 2 shows all the Azure related stuff I have installed
I have a coworker who has Visual Studio 2015 and can load the Azure project in the solution without a problem (see image 3). So it's clear that you don't have to upgrade the project.
I'm going to try installing VS 2013 Community Edition + Azure 2.7 tools to see if that satisfies it. I'm grasping at straws at this point.
Any ideas?
A coworker helped me to come up with the solution:
Go to the "Microsoft Azure SDK for .NET - 2.6" page here:
https://www.microsoft.com/en-us/download/details.aspx?id=46892
Download "MicrosoftAzureTools.VS140.exe" and install it
Run appwiz.cpl from the run prompt and filter on "azure" in upper right
You should see "Microsoft Azure Tools for Microsoft Visual Studio 2015 - v2.6"
Open Visual Studio 2015 again and your project should now load without prompting to upgrade. Do a Rebuild All just in case to make sure it builds.
It turns out I had dang near everything installed except that one 2015 tools + 2.6 Azure combination.
