Core CLR に切り替える

dotnet

Core CLR は Side by side を dotnet framework ごとやるやつなので
dotnet framework アセンブリごとをWebに含めてdeployするようになる。
Webアプリごとにdotnet frameworkのバージョンを別にもてるようになる。



c:\oss\aspnet\Home>kvm upgrade -svrc50

c:\oss\aspnet\Home>kvm alias

Alias   Name

 -----   ----

default KRE-svrc50-x86.0.1-alpha-build-0481

切り替わったようだ。



c:\oss\aspnet\Home>cd samples\HelloMvc

c:\oss\aspnet\Home\samples\HelloMvc>set KRE_TRACE=1

c:\oss\aspnet\Home\samples\HelloMvc>k web

Loaded Module: klr.core45.dll

Found DLL Export: CallApplicationMain

 ...

klr.net45.dll から klr.core45.dll に変わってもきちんと動いた。



>dir /S /B %USERPROFILE%\.kre\packages\KRE-svr50-x86.0.1-alpha-build-0481 | findstr .dll | wc -w

      14

>dir /S /B %USERPROFILE%\.kre\packages\KRE-svrc50-x86.0.1-alpha-build-0481 | findstr .dll | wc -w

      232

dllがものすごく増えるのでAzureへのdeployさらに遅くなりそうだな。。。
それともdeploy時にAzure側でdllをとってくるようになるのかな。。。

相変わらずファイルはBOMつきだな。。。。
Startup で DependencyInjection がいる。AddMvc でAsp.NET MVC で必要なクラスや Controller もコンテナに登録にいってる。
ActionResultからIActionResultに変更。
ViewBagは健在。Razor の構文はかわりなしな感じ。

Global.asax、Web.Conig がいない。
実際には https://github.com/aspnet/MusicStore/tree/dev/src/MusicStore をみると Web.Conig はいる。IISでうごかすためにもこれは残るのだろう。Razor も async/await している。。。

asp.net vnext とは？

dotnet

Entity Framework が軽量になるやつを開発しているというので見に行ったら
asp.net vnext としてIIS依存をなくす？プロジェクトが動いていた。
なぜか codeplex じゃなくて github だ。

https://github.com/aspnet
DependencyInjection と Logging がちゃんとついて
ASP.NET MVC 6 + SingnalR 3 + EntityFramework 7
がmono上でもIISなしでうごくっていうのはものすごくいい感じ。
DataCommon.SQLite がはいっているのもよい。

さわりとしては以下を参照でいいのだろう。

ASP.NET vNext(MVC / Web API / Web Pages 6, Entity Framework 7, SignalR 3)が TechEd NA で発表された話

Eclipseを起動するJava8で起動しDeployするとGAEで実行時エラー

gae

Google App Engine はまだJava8に対応していないので、EclipseをJava8で起動して、プロジェクトの設定をJava7にしてビルド。
ローカルでdebugしてうまくいったので Google Plugin for Eclipse で Google App Engine にdeployすると上記のエラーがでる。
Upload時にjspのコンパイルをしているためだと思われる。
Java7でEclipseを起動しなおしてdeployした実行時エラーはでなくなった。
