I have created a blank .NET Core 2.2 project and immediately published it. This is my published content:
If I now add the following into my .csproj:
<MvcRazorCompileOnPublish>true</MvcRazorCompileOnPublish>
Then publish again, I get the following published content:
I cannot find an explanation anywhere for what the difference is between WebApplication3.Views.dll and WebApplication3.PrecompiledViews.dll. They both look like a library of precompiled views to me. If that's the case, what's the point of the config setting?

Is there a way I can compile all my razor views (to verify) any time I need? I found this doc which shows how it compiles on publish https://learn.microsoft.com/en-us/aspnet/core/mvc/views/view-compilation?view=aspnetcore-2.1&tabs=aspnetcore2x.
I am looking for an option within visual studio or even better via CLI that compiles and validates all views. I did find this official razor CLI tool in preview, but no documentation: https://www.nuget.org/packages/Microsoft.AspNetCore.Razor.Tools/1.1.0-preview4-final
Well, you can publish any time you need. The name ‘publish’ does not mean ‘push my site to the coliseum of public opinion’ :-)
All that it does stays local, and dotnet publish will by default create a directory under your project bin folder with, as you say, compiled views and other artefacts.
Per this comment, with .NET core 2.1 you can compile razor views at build time without needing to publish, by adding these two lines to the <PropertyGroup> section of your project file:
<RazorCompileOnBuild>true</RazorCompileOnBuild>
<ResolvedRazorCompileToolset>RazorSdk</ResolvedRazorCompileToolset>
This will cause them to compile to a [project].Views.dll, and you'll no longer need to distribute the cshtml files.
In .NET Core 2 Web API app, Publish to folder feature in MS VS 2017 produce:
<ProjectAssembly>.PrecompiledViews.dll
<ProjectAssembly>.PrecompiledViews.pdb
Offical docs says that PrecompiledViews related to precompiling Razor Views, but my API doesn't contain any views or static files, just REST endpoints that return json.
Using .Net reflector I found the PrecompiledViews.dll empty.
So I deleted PrecompiledViews.dll and tested my API and it seems to work fine without any warnings or exceptions.
Is it safe to delete PrecompiledViews.dll and pdp if the API not using any razor views? If yes, Is there option in VS 2017 to stop publishing unused PrecompiledViews?
You are right, the precompile step always emits an assembly and doesn't check if there are actually views. You can disable the precompilation step by putting this into your csproj file:
<PropertyGroup>
<MvcRazorCompileOnPublish>false</MvcRazorCompileOnPublish>
</PropertyGroup>
This will then activate the normal copilation context preservation (refs subfolder). To deactivate this as well, add
<PreserveCompilationContext>false</PreserveCompilationContext>
to the property group.
The question is how to resolve conflicts between versions of assemblies in my project that was upgraded to MVC4 and EF5?
The problem is manifest in the fact that my controllers and models can include System.Data.Objects, but now my views.
I am using MVC 4, my project was upgraded from MVC 3.
Entity Framework is version 5.
I have a controller that is able to use objectcontext from System.Data.Objects.
My Usings:
using System.Data.Objects;
using System.Data.Entity;
When I try to include the using in the view form System.Data.Objects, I get :
CS0234: The type or namespace name 'Objects' does not exist in the namespace 'System.Data' (are you missing an assembly reference?)
I am targeting .net 4.5
My Build Displays this message:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(1561,5): warning MSB3247: Found conflicts between different versions of the same dependent assembly.
You can build your solution in diagnostic mode to get more detailed information about the error.
Open the VS Options dialog (Tools > Options), navigate to the "Projects and Solutions" node and select "Build and Run". Change the MS Build project build output verbosity to Diagnostic.
Have a look here.
If you look at the build message, it states the 4.0 version of the .net framework is referenced... Is there a setting in your project file or web/app.config specifying a conflicting version of the .net framework?
Are you familiar with fuslog? you can set it up to log all assembly bindings that .net is doing while running your application. You should then be able to see detailed information on what is getting bound when. If you still can't figure it out, you can always do a binding redirect on that .dll in the web.config.
http://msdn.microsoft.com/en-us/library/eftw1fys.aspx -- binding redirects
http://msdn.microsoft.com/en-us/library/e74a18c4(v=vs.71).aspx -- fusion log viewer
Set up fusion logger and take a look at what the output is. If you don't get an answer from that, try the binding redirect (which would give you at least a temporary solution).
In the directory I was publishing to, there was a folder named aspnet_client. I moved it (instead of deleting it), republished, and it worked. I'm not sure why that folder decided to give me trouble out of the blue.
So, i'm developing my razor macroscripts in Visual studio for my Umbraco project.
Everything is working fine, but there are two things really annoying.
If I want to make a new CSHTML file the best solution for this is to duplicate an existing file.
I dont have full razor IntelliSense like e.g. Html.Raw
Is there a way to configure my project to use this features? Didn't find a .cshtml template yet.
You need to have the MVC Framework installed, then when you open the project as a website, you should be able to create and edit cshtml files with syntax highlighting. See my answer to the following post for more details:
Setting up local development environment for Umbraco
If your project is a web site/application then the mvc templates aren't available (they only show up in MVC projects). You can just create a text file and name it with the .cshtml extension though (you could set up your own template for this in VS if you wanted to).
To get intellisense in your Razor files, see Doug Robar's blog post on the subject
As an alternative if you go into the Umbraco admin, go to the 'Developer' section and right click on 'Scripting Files' you can create razor scripts directly (and this will save the new .cshtml directly into your 'macroScripts' folder - although in VS2010 you will need to right click on the new script and choose 'include in project').
Also this will allow you to base your new razor macroscript on one of the pre-built snippets so you may get a bit of core functionality for free.
From Umbraco 6 on it's very convenient to install Umbraco on your local file system with Visual Studio and NuGet. Given that you have the MVC Framework installed and you use Visual Studio 2012 or above, you get full Razor support in Visual studio.
Umbraco Our has a great blogpost about this where they described the steps below in detail (with screenshots!).
Create an Empty Web Application.
Install Umbraco using Manage Nuget Packages ('Umbraco CMS') or the Package manager console (Install-Package UmbracoCms)
NuGet will then download dependencies and will install all of Umbraco's files in your new solution. During this process it will ask if it is allowed to overwrite your web.config file. (Make a back up of your existing web.config if you install Umbraco in an existing project)
Finally, don't forget to run your project hitting F5. You'll see that whenever you try to add or edit a file in your views folder you have razor support and intellisense
D:\Web\CityV2\App_Code\ActiveRecord.tt(0,0) : error CS0006: Compiling transformation: Metadata file 'MySql.Data' could not be found
Let me start by saying I'm using VWD 2008 Express.
These are the steps I've taken so far:
Created an entirely new project
Added references for Subsonic.Core.dll and MySql.Data.dll
Copied Active Record templates to project
Changed all <## include file="SQLServer.ttinclude" #> to <## include file="MySQL.ttinclude" #>
Copied the MySQL.ttinclude and Settings.ttinclude from the TemplateProviders folder
Updated Settings.ttinclude with my connectionstring and database information
Updated the Settings.ttinclude and created the external tool mapping as per ranomore's instructions
Attempted to build the code from the templates and received the error
I then realized that I didn't have MySql Connector "installed" on my dev box (even though I added a reference to the bin). So I proceeded to MySQL.com and downloaded the latest 6.0.4 connector msi and installed it (GAC). The error no longer appears, but neither does anything else: no new classes, no new errors, nothing [and yes, I refreshed the project after running the command ;-)].
Two things:
Am I missing a step somewhere?
Is there a way build the templates without needing MySQL installed to the GAC?
Unfortunately SubSonic 3 doesn't support VWD 2008 Express (or more specifically VWD doesn't support t4). There is a sort of workaround that ranomore came up with but it will require some work by you. See the following question for more details:
SubSonic ASP.NET MVC sample in Visual Web Developer Express
EDIT: I should have read your question properly you obviously already have the link above. Maybe worth your while downloading the trial of VS professional and seeing if you have more luck with that to see if it's worth outlaying the cash to buy it.
