Compile Asp.Net Core MVC view when running 3.0

Under normal circumstances, the view at the time of generation will become xxx.Views.dll, during development, this is very easy, because a lot of the time, we just modify a style, adjust some JavaScript code, this time should project commissioning paused, looking at page after generating effect.

First by nuget console installation package:

Install-Package Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation -Version 3.0.0

Then Startup.cs file, adding ConfigureServices function:

.AddRazorRuntimeCompilation()

//如下
services.AddMvc()
.AddRazorRuntimeCompilation()
.AddNewtonsoftJson()
.SetCompatibilityVersion(Microsoft.AspNetCore.Mvc.CompatibilityVersion.Version_3_0);

Finally add (VS2019 double-click the project) in the project file:

Note: Do not perform the following operations can also be run compile, but when you publish Views directory will be compiled as *** Views.dll file.

<RazorCompileOnBuild>false</RazorCompileOnBuild>
<RazorCompileOnPublish>false</RazorCompileOnPublish>

After the clean-up solution can recompile.

Note: only modify XML project files increase, it will complain when debugging, prior to the need for a two-step operation.
